Subject: [PATCH 001/544] [SCEV][NFC] Introduce isBasicBlockEntryGuardedByCond

Currently, we have `isLoopEntryGuardedByCond` method in SCEV, which
checks that some fact is true if we enter the loop. In fact, this is just a
particular case of more general concept `isBasicBlockEntryGuardedByCond`
applied to given loop's header. In fact, the logic if this code is largely
independent on the given loop and only cares code above it.

This patch makes this generalization. Now we can query it for any block,
and `isBasicBlockEntryGuardedByCond` is just a particular case.

Subject: [PATCH 002/544] [LoopDeletion] Forget loop before setting values to
 undef

After D71539, we need to forget the loop before setting the incoming
values of phi nodes in exit blocks, because we are looking through those
phi nodes now and the SCEV expression could depend on the loop phi. If
we update the phi nodes before forgetting the loop, we miss those users
during invalidation.

Subject: [PATCH 007/544] [IndVarSimplify] Fix Modified status for removal of
 overflow intrinsics

When removing an overflow intrinsic the Changed status in SimplifyIndvar
was not set, leading to the IndVarSimplify pass returning an incorrect
status.

This was caught using the check introduced by D80916.

As pointed out in the code review, a similar bug may exist for
eliminateTrunc().

Subject: [PATCH 013/544] [SystemZ] Don't emit PC-relative memory accesses to
 unaligned symbols.

In the presence of packed structures (#pragma pack(1)) where elements are
referenced through pointers, there will be stores/loads with alignment values
matching the default alignments for the element types while the elements are
in fact unaligned. Strictly speaking this is incorrect source code, but is
unfortunately part of existing code and therefore now addressed.

This patch improves the pattern predicate for PC-relative loads and stores by
not only checking the alignment value of the instruction, but also making
sure that the symbol (and element) itself is aligned.

Fixes https://bugs.llvm.org/show_bug.cgi?id=44405

Subject: [PATCH 018/544] [AArch64] Add v8.5 Branch Target Identification
 support.

The .note.gnu.property must be in the assembly file to indicate the
support for BTI otherwise BTI will be disabled for the whole library.
__unw_getcontext and libunwind::Registers_arm64::jumpto() may be called
indirectly therefore they should start with a landing pad.

Subject: [PATCH 019/544] [mlir][Linalg] Refactor Linalg creation of loops to
 allow passing iterArgs - NFC

This revision changes the signatures of helper function that Linalg uses to create loops so that they can also take iterArgs.
iterArgs are asserted empty to ensure no functional change.
This is a mechanical change in preparation of tiling on linalg on tensors to avoid  polluting the implementation with an NFC change.

Subject: [PATCH 020/544] [GlobalISel] fix widenScalarUnmerge if widen type is
 not a multiple of destination type

Fix creation of illegal unmerge when widen was requested to a type which
is not a multiple of the destination type. E.g. when trying to widen
an s48 unmerge to s64 the existing code would create an illegal unmerge
from s64 to s48.

Instead, create further unmerges to a GCD type, then use this to remerge
these intermediate results to the actual destinations.

Subject: [PATCH 021/544] [mlir][Linalg] Refactor Linalg op initTensors support
 - NFC

Manually-defined named ops do not currently support `init_tensors` or return values and may never support them. Add extra interface to the StructuredOpInterface so that we can still write op-agnostic transformations based on StructuredOpInterface.

This is an NFC extension in preparation for tiling on tensors.

Subject: [PATCH 023/544] [InstCombine] visitTrunc - trunc (lshr (sext A), C)
 --> (ashr A, C) non-uniform support

This came from @lebedev.ri's suggestion to use m_SpecificInt_ICMP for D88429 - since I was going to change the m_APInt to m_Constant for that patch I thought I would do it for the only other user of the APInt first.

I've added a ConstantExpr::getUMin helper - its trivial to add UMAX/SMIN/SMAX but thought I'd wait until we have use cases.

Subject: [PATCH 025/544] [Sema] Address-space sensitive check for unbounded
 arrays (v2)

Check applied to unbounded (incomplete) arrays and pointers to spot
cases where the computed address is beyond the largest possible
addressable extent of the array, based on the address space in which the
array is delcared, or which the pointer refers to.

Check helps to avoid cases of nonsense pointer math and array indexing
which could lead to linker failures or runtime exceptions.  Of
particular interest when building for embedded systems with small
address spaces.

This is version 2 of this patch -- version 1 had some testing issues
due to a sign error in existing code.  That error is corrected and
lit test for this chagne is extended to verify the fix.

Subject: [PATCH 027/544] [mlir] Expose Dialect class and registration/loading
 to C API

- Add a minimalist C API for mlir::Dialect.
- Allow one to query the context about registered and loaded dialects.
- Add API for loading dialects.
- Provide functions to register the Standard dialect.

When used naively, this will require to separately register each dialect. When
we have more than one exposed, we can add variadic macros that expand to
individual calls.

Subject: [PATCH 033/544] [InstCombine] use redirect of input file in
 regression tests; NFC

This is a repeat of 1880092722 from 2009. We should have less risk
of hitting bugs at this point because we auto-generate positive CHECK
lines only, but this makes things consistent.

Copying the original commit msg:
"Change tests from "opt %s" to "opt < %s" so that opt doesn't see the
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename."

Subject: [PATCH 035/544] [scudo][standalone] Fix Primary's ReleaseToOS test

Said test was flaking on Fuchsia for non-obvious reasons, and only
for ASan variants (the release was returning 0).

It turned out that the templating was off, `true` being promoted to
a `s32` and used as the minimum interval argument. This meant that in
some circumstances, the normal release would occur, and the forced
release would have nothing to release, hence the 0 byte released.

The symbols are giving it away (note the 1):
```
scudo::SizeClassAllocator64<scudo::FixedSizeClassMap<scudo::DefaultSizeClassConfig>,24ul,1,2147483647,false>::releaseToOS(void)
```

This also probably means that there was no MTE version of that test!

Subject: [PATCH 040/544] [clangd] Disable msan instrumentation for generated
 Evaluate().

MSAN build times out for generated DecisionForest inference runtime.

A solution worth trying is splitting the function into 300 smaller
functions and then re-enable msan.

For now we are disabling instrumentation for the generated function.

Subject: [PATCH 041/544] NFC, add a missing stdlib include for the use of
 abort

The FatalErrorHandler.cpp file uses 'abort', but doesn't include
'stdlib.h'. This causes a build error when modules are used in clang.

Subject: [PATCH 044/544] [lldb] Also configure lldb_framework_dir in the
 lit.site.cfg.py

Configuring the variable in CMake isn't enought, because the build mode
can't be resolved until execution time, which requires the build mode to
be substituted by lit.

Subject: [PATCH 047/544] [libc++] Add a regression test for erasing from a
 vector

After rebasing my trivially-relocatable branch, this behavior was broken...
but no libc++ unit test caught it! Add a regression test specifically for
erasing out of a vector.

Subject: [PATCH 048/544] [flang][msvc] Avoid templated initializer list
 initialization of vector. NFC.

The Microsoft compiler emits an error when populating the vector with a single element of a templated argument using the brace syntax. The error is:
```
constant.h(102,1): error C2664: 'std::vector<Fortran::evaluate::value::Complex<...>, ...>::vector(std::initializer_list<_Ty>,const _Alloc &)': cannot convert argument 1 from 'initializer list' to 'std::initializer_list<_Ty>'
```
To work around this error, we replace the templated constructor with one for the expected type. Conversion to the element type has to be done by the caller.

This patch is part of the series to make flang compilable with MS Visual Studio <http://lists.llvm.org/pipermail/flang-dev/2020-July/000448.html>.

As @kadircet mentions in D84912#2184144, `findNearbyIdentifier()` traverses the whole file if there is no identifier for the word.
This patch ensures give up after 2^N lines in any case.

Subject: [PATCH 054/544] [BuildLibCalls] Add noundef to the returned pointers
 of allocators and argument of free

This patch adds noundef to the returned pointers of allocators (malloc, calloc, ...)
and the pointer argument of free.
The returned pointer of allocators cannot be poison or (partially) undef.
Since the pointer that is given to free should precisely have zero offset,
it cannot be poison or (partially) undef too.

For the size arguments of allocators, noundef wasn't attached simply because
I wasn't sure whether attaching it is okay or not.

Subject: [PATCH 058/544] [ELF] Fix multiple -mllvm after D70378

Fixes https://reviews.llvm.org/D70378#2299569 Multiple -mllvm is intended to be supported.

We don't have a proper test for `-plugin-opt=-`. This patch adds the test as well.

Subject: [PATCH 059/544] [InstCombine] visitTrunc - trunc (*shr (trunc A), C)
 --> trunc(*shr A, C)

Attempt to fold trunc (*shr (trunc A), C) --> trunc(*shr A, C) iff the shift amount if small enough that all zero/sign bits created by the shift are removed by the last trunc.

Helps fix the regressions encountered in D88316.

I've tweaked a couple of shift values as suggested by @lebedev.ri to ensure we have coverage of shift values close (above/below) to the max limit.

Subject: [PATCH 061/544] Add -fprofile-update={atomic,prefer-atomic,single}

GCC 7 introduced -fprofile-update={atomic,prefer-atomic} (prefer-atomic is for
best efforts (some targets do not support atomics)) to increment counters
atomically, which is exactly what we have done with -fprofile-instr-generate
(D50867) and -fprofile-arcs (b5ef137c11b1cc6ae839ee75b49233825772bdd0).
This patch adds the option to clang to surface the internal options at driver level.

GCC 7 also turned on -fprofile-update=prefer-atomic when -pthread is specified,
but it has performance regression
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89307). So we don't follow suit.

Subject: [PATCH 062/544] [NFC][regalloc] Unit test for AllocationOrder
 iteration.

Added unittests. In the process, separated core construction - which just
needs the hits, order, and 'HardHints' values - from construction from
current register allocation state, to simplify testing.

Subject: [PATCH 063/544] Adds MLIR C-API for marshaling Python capsules.

* Providing stable, C-accessible definitions for bridging MLIR Python<->C APIs, we eliminate inter-extension dependencies (i.e. they can all share a diamond dependency on the MLIR C-API).
* Just provides accessors for context and module right now.
* Needed in NPComp in ~a week or so for high level Torch APIs.

+    The `body` region attached to the `async.execute` operation semantically

+    The actual concurrency semantics depends on the dialect lowering to the

+    implicit dependency from "compute1" to "compute0" (e.g. via shared global
+    state). All dependencies must be made explicit with async execute arguments
+    (`async.token` or `async.value`).
+
+    Example:
+
+    ```mlir
+    %0 = async.execute {
+      "compute0"(...)
+      async.yield
+    } : !async.token

Subject: [PATCH 067/544] Revert "Revert "Add the ability to write target
 stop-hooks using the ScriptInterpreter.""

This reverts commit f775fe59640a2e837ad059a8f40e26989d4f9831.

I fixed a return type error in the original patch that was causing a test failure.
Also added a REQUIRES: python to the shell test so we'll skip this for
people who build lldb w/o Python.
Also added another test for the error printing.

+ Writing Target Stop-Hooks in Python:
+ ------------------------------------
+
+ Stop hooks fire whenever the process stops just before control is returned to the
+ user.  Stop hooks can either be a set of lldb command-line commands, or can
+ be implemented by a suitably defined Python class.  The Python based stop-hooks
+ can also be passed as set of -key -value pairs when they are added, and those
+ will get packaged up into a SBStructuredData Dictionary and passed to the
+ constructor of the Python object managing the stop hook.  This allows for
+ parametrization of the stop hooks.
+
+ To add a Python-based stop hook, first define a class with the following methods:
+

+-------------------------
+  Stop hooks can run a list of lldb commands by providing one or more
+  --one-line-command options.  The commands will get run in the order they are 
+  added.  Or you can provide no commands, in which case you will enter a
+  command editor where you can enter the commands to be run.
+  
+Python Based Stop Hooks:
+------------------------
+  Stop hooks can be implemented with a suitably defined Python class, whose name
+  is passed in the --python-class option.
+  
+  When the stop hook is added, the class is initialized by calling:
+  
+    def __init__(self, target, extra_args, dict):
+

+  Then when the stop-hook triggers, lldb will run the 'handle_stop' method. 
+  The method has the signature:

+    def handle_stop(self, exe_ctx, stream):

+    exe_ctx: An SBExecutionContext for the thread that has stopped.
+    stream: An SBStream, anything written to this stream will be printed in the
+            the stop message when the process stops.
+
+    Return Value: The method returns "should_stop".  If should_stop is false
+                  from all the stop hook executions on threads that stopped
+                  with a reason, then the process will continue.  Note that this

Subject: [PATCH 069/544] Use "default member initializer" instead of "in-class
 initializer" for diagnostics.

This changes some diagnostics to use terminology from the standard
rather than invented terminology, which improves consistency with other
diagnostics as well. There are no functional changes intended other
than wording and naming.

Subject: [PATCH 070/544] [ValueTracking] Early exit known non zero for phis

After D88276 we no longer expect computeKnownBits() to prove
non-zeroness for cases where isKnownNonZero() can't, so don't
fall through to it.

Subject: [PATCH 071/544] [mlir] Support return and call ops in bare-ptr
 calling convention

This patch adds support for the 'return' and 'call' ops to the bare-ptr
calling convention. These changes also align the bare-ptr calling
convention code with the latest changes in the default calling convention
and reduce the amount of customization code needed.

Subject: [PATCH 072/544] [InstCombine] ease alignment restriction for
 converting masked load to normal load

I think we initially made this fold conservative to be safer, but we do not
need the alignment attribute/metadata limitation because the masked load
intrinsic itself specifies the alignment. A normal vector load is better for
IR transforms and should be no worse in codegen than the masked alternative.
If it is worse for some target, the backend can reverse this transform.

Subject: [PATCH 075/544] [lldb/docs] Remove manual codesigning documentation

The `macos-setup-codesign.sh` script has been in place for over two years. If there are no known issues, it's a good time to drop the manual steps from the docs.

-* Double click on your new ``lldb_codesign`` certificate
-* Turn down the "Trust" disclosure triangle, scroll to the "Code Signing" trust

The destructor must be defined in the implementation class so that it
can be called, as Vedant Kumar pointed out in:

'''
What were your thoughts, re:

   Does this need to be `virtual ~Trace() = ...`?

      Otherwise, when a std::shared_ptr<Trace> is destroyed, the
      destructor for the derived TraceIntelPT instance won't run.

Subject: [PATCH 080/544] [lldb] Hoist --server argument out of
 LLDB_TEST_COMMON_ARGS (NFC)

Give the server argument its own variable (LLDB_TEST_SERVER) so that we
can configure it in lit.site.cfg.py if we so desire.

Subject: [PATCH 081/544] [libc++] Rename the -fno-rtti Lit feature to just
 no-rtti

This is consistent to the way we name other Lit features, and it removes
the possibility for confusing the Lit feature with the actual compiler
flag.

Subject: [PATCH 082/544] Better diagnostics for anonymous bit-fields with
 attributes or an initializer.

The current C++ grammar allows an anonymous bit-field with an attribute,
but this is ambiguous (the attribute in that case could appertain to the
type instead of the bit-field). The current thinking in the Core Working
Group is that it's better to disallow attributes in that position at the
grammar level so that the ambiguity resolves in favor of applying to the
type.

During discussions about the behavior of the attribute, the Core Working
Group also felt it was better to disallow anonymous bit-fields from
specifying a default member initializer.

This implements both sets of related grammar changes.

It's hard to come up with a test case, since mlir-opt always add location info after parsing it (?)

Subject: [PATCH 086/544] [ms] [llvm-ml] Add support for .radix directive, and
 accept all radix specifiers

Add support for .radix directive, and radix specifiers [yY] (binary), [oOqQ] (octal), and [tT] (decimal).

Also, when lexing MASM integers, require radix specifier; MASM requires that all literals without a radix specifier be treated as in the default radix. (e.g., 0100 = 100)

Relanding D87400, now with fewer ms-inline-asm tests broken!

Subject: [PATCH 091/544] [ms] [llvm-ml] Create the @feat.00 symbol, and
 populate it appropriately

@feat.00 is a bitfield read by Microsoft-style linkers, and is required to signal (e.g.) /safeseh support on 32-bit systems.

Subject: [PATCH 093/544] [flang][msvc] Define implicit conversion from
 UnsignedInt128 to int64_t.

The custom implementation of UnsignedInt128 has an implicit conversion operator to unit64_t, but not int64_t. Considering that the former is already truncating, and C++ implicitly converts uint64_t to int64_t, UnsignedInt128  should also support an implicit conversion to int64_t. An analogous conversion would be from uint32_t to int16_t.

Without the conversion operator overload, the msvc emits the following error:
```
descriptor-io.h(44): error C2440: 'static_cast': cannot convert from 'A' to 'int64_t'
        with
        [
            A=Fortran::common::uint128_t
        ]
```

This patch is part of the series to make flang compilable with MS Visual Studio <http://lists.llvm.org/pipermail/flang-dev/2020-July/000448.html>.

Subject: [PATCH 094/544] [flang][msvc] Define access flags under Windows. NFC.

The flags F_OK, R_OK and W_OK are defined in unistd.h, which does not exist under the Windows platform. Windows still defines the `access` function. Its access flags are documented at https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/access-waccess. For compatibility, define the flags F_OK, R_OK and W_OK using these constants.

Subject: [PATCH 095/544] [nfc][libomptarget] Drop parameter to named_sync

[nfc][libomptarget] Drop parameter to named_sync

named_sync has one call site (in sync.cu) where it always passed L1_BARRIER.
Folding this into the call site and dropping the macro is a simplification.

amdgpu doesn't have ptx' bar.sync instruction. A correct implementation of
__kmpc_impl_named_sync in terms of shared memory is much easier if it can
assume that the barrier argument is this constant. Said implementation is left
for a second patch.

Subject: [PATCH 096/544] Improve the representation of <compare>'s zero-only
 type.

* Use an empty struct instead of a member pointer to represent this
  type, so that we don't actually pass a zero member pointer at runtime.

* Mark the constructor as consteval to ensure that no code is emitted
  for it whenever possible.

* Add a honeypot constructor to reject all non-int arguments, so that
  the only argument that can arrive at the real constructor is the
  literal 0.

This results in better generated code, and rejecting invalid comparisons
against nullptr, 0L, and so on, while also rejecting invalid comparisons
against (1-1) and similar that would be allowed if we required an
integer constant expression with value 0.

Subject: [PATCH 102/544] Fix a variety of minor issues with ObjC method
 mangling:

- Fix a memory leak accidentally introduced yesterday by using CodeGen's
  existing mangling context instead of creating a new context afresh.

- Move GNU-runtime ObjC method mangling into the AST mangler; this will
  eventually be necessary to support direct methods there, but is also
  just the right architecture.

- Make the Apple-runtime method mangling work properly when given an
  interface declaration, fixing a bug (which had solidified into a test)
  where mangling a category method from the interface could cause it to
  be mangled as if the category name was a class name.  (Category names
  are namespaced within their class and have no global meaning.)

- Fix a code cross-reference in dsymutil.

Based on a patch by Ellis Hoag.

Subject: [PATCH 112/544] [AIX] asm output: use character literals in byte
 lists for strings

This patch improves the assembly output produced for string literals by
using character literals in byte lists. This provides the benefits of
having printable characters appear as such in the assembly output and of
having strings kept as logical units on the same line.

Subject: [PATCH 113/544] [X86] Increase the depth threshold required to form
 VPERMI2W/VPERMI2B in shuffle combining

These instructions are implemented with two port 5 uops and one port 015 uop so they are more complicated that most shuffles.

This patch increases the depth threshold for when we form them during shuffle combining to try to limit increasing the number of uops especially on port 5.

Subject: [PATCH 114/544] [GlobalISel] Fix multiply with overflow intrinsics
 legalization generating invalid MIR.

During lowering of G_UMULO and friends, the previous code moved the builder's
insertion point to be after the legalizing instruction. When that happened, if
there happened to be a "G_CONSTANT i32 0" immediately after, the CSEMIRBuilder
would try to find that constant during the buildConstant(zero) call, and since
it dominates itself would return the iterator unchanged, even though the def
of the constant was *after* the current insertion point. This resulted in the
compare being generated *before* the constant which it was using.

There's no need to modify the insertion point before building the mul-hi or
constant. Delaying moving the insert point ensures those are built/CSEd before
the G_ICMP is built.

Fixes PR47679

Subject: [PATCH 121/544] [RDA] Switch isSafeToMove iterators

So forwards is forwards and backwards is reverse. Also add a check
so that we know the instructions are in the expected order.

Subject: [PATCH 123/544] [clangd] Extract options struct for ClangdLSPServer.
 NFC

In preparation for making moving TweakFilter from ClangdServer::Options to
a ClangdLSPServer option, and letting it vary per-request.
(In order to implement CodeActionParams.only)

Also a general overdue cleanup.

+
+    The `atan2` operation takes two operands and returns one result, all of
+    which must be of the same type.  This type may be a floating point scalar
+    type, a vector whose element type is a floating point type, or a floating
+    point tensor.
+
+    The 2-argument arcus tangent `atan2(y, x)` returns the angle in the
+    Euclidian plane between the positive x-axis and the ray through the point
+    (x, y).  It is a generalization of the 1-argument arcus tangent which
+    returns the angle on the basis of the ratio y/x.
+
+    See also https://en.wikipedia.org/wiki/Atan2

Subject: [PATCH 127/544] [llvm-readobj][ARM] - Improve support of printing
 unwind (-u) information for non-relocatable objects.

This is the one more patch for https://bugs.llvm.org/show_bug.cgi?id=47581

It fixes how we print an information for the Generic model. With this patch
we are able to read values from `.ARM.extab` and dump proper personality routines names/addresses.

Subject: [PATCH 128/544] [llvm-readobj][test] - Stop using few precompiled
 binaries in mips-got.test

This removes 4 input files (one source file and 3 precompiled binaries) from
`mips-got.test` (now YAMLs are used instead) and also makes the testing of
the GNU output a bit stricter (`--strict-whitespace --match-full-lines`).

Subject: [PATCH 129/544] Revert "[gardening] Replace some uses of
 setDebugLoc(DebugLoc()) with dropLocation(), NFC"

Some of the buildbots have croaked with this patch, for examples failures
that begin in this build:

  http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/builds/29933

This reverts commit 674f57870f4c8a7fd7b629bffc85b149cbefd3e0.

Subject: [PATCH 132/544] [clangd][remote] Make sure relative paths are
 absolute with respect to posix style

Relative paths received from the server are always in posix style. So
we need to ensure they are relative using that style, and not the native one.

Subject: [PATCH 134/544] [SplitKit] Cope with no live subranges in
 defFromParent

Following on from D87757 "[SplitKit] Only copy live lanes", it is
possible to split a live range at a point when none of its subranges
are live. This patch handles that case by inserting an implicit def
of the superreg.

Patch by Quentin Colombet!

Subject: [PATCH 137/544] [X86] Support Intel Key Locker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Key Locker provides a mechanism to encrypt and decrypt data with an AES key without having access
to the raw key value by converting AES keys into “handles”. These handles can be used to perform the
same encryption and decryption operations as the original AES keys, but they only work on the current
system and only until they are revoked. If software revokes Key Locker handles (e.g., on a reboot),
then any previous handles can no longer be used.

Subject: [PATCH 140/544] [InstCombine] recognizeBSwapOrBitReverseIdiom -
 recognise zext(bswap(trunc(x))) patterns (PR39793)

PR39793 demonstrated an issue where we fail to recognize 'partial' bswap patterns of the lower bytes of an integer source.

In fact, most of this is already in place collectBitParts suitably tags zero bits, so we just need to correctly handle this case by finding the zero'd upper bits and reducing the bswap pattern just to the active demanded bits.

Subject: [PATCH 143/544] [mlir][Linalg] Tile sizes for Conv ops vectorization
 added as pass arguments

Current setup for conv op vectorization does not enable user to specify tile
sizes as well as dimensions for vectorization. In this commit we change that by
adding tile sizes as pass arguments. Every dimension with corresponding tile
size > 1 is automatically vectorized.

Differential Revision: https://reviews.llvm.org/D88533

Subject: [PATCH 144/544] [SCEV] Verify that all mapped SCEV AddRecs refer to
 valid loops.

This check helps to guard against cases where expressions referring to
invalidated/deleted loops are not properly invalidated.

The additional check is motivated by the reproducer shared for 8fdac7cb7abb
and I think in general make sense as a sanity check.

Subject: [PATCH 145/544] InstCombine] collectBitParts - cleanup variable
 names. NFCI.

Fix a number of WShadow warnings (I was used as the instruction and index......) and fix cases to match style.

Also, replaced the Bit APInt mask check in AND instructions with a direct APInt[] bit check.

We weren't looking at global uses of a value, so we could happily
overwrite the register incorrectly.

Subject: [PATCH 148/544] [InstCombine] recognizeBSwapOrBitReverseIdiom -
 cleanup bswap/bitreverse detection loop. NFCI.

Early out if both pattern matches have failed (or we don't want them). Fix case of bit index iterator (and avoid Wshadow issue).

Subject: [PATCH 151/544] [VPlan] Change recipes to inherit from VPUser instead
 of a member var.

Now that VPUser is not inheriting from VPValue, we can take the next
step and turn the recipes that already manage their operands via VPUser
into VPUsers directly. This is another small step towards traversing
def-use chains in VPlan.

This is NFC with respect to the generated code, but makes the interface
more powerful.

Subject: [PATCH 155/544] [InstCombine] recognizeBSwapOrBitReverseIdiom - merge
 the regular/trunc+zext paths. NFCI.

There doesn't seem to be any good reason for having a separate path for when we bswap/bitreverse at a smaller size than the destination size - so merge these to make the instruction generation a lot clearer.

Subject: [PATCH 157/544] [PowerPC] Remove support for VRSAVE
 save/restore/update.

After removal of Darwin as a PowerPC subtarget, the VRSAVE
save/restore/spill/update code is no longer needed by any supported
subtarget, so remove it while keeping support for vrsave and related instruction
aliases for inline asm. I've pre-commited tests to document the existing vrsave
handling in relation to @llvm.eh.unwind.init and inline asm usage, as
well as a test which shows a beahviour change on AIX related to
returning vector type as we were wrongly emiting VRSAVE_UPDATE on AIX.

Subject: [PATCH 158/544] [GlobalISel] Fix incorrect setting of ValNo when
 splitting

Before, for each original argument i, ValNo was set to i + PartIdx, but
ValNo is intended to reflect the index of the value before splitting.
Hence, ValNo should always be set to i and not consider the PartIdx.

Subject: [PATCH 160/544] [sanitizers] Fix internal__exit on Solaris
 `TestCases/log-path_test.cpp` currently `FAIL`s on Solaris:

  $ env ASAN_OPTIONS=log_path=`for((i=0;i<10000;i++)); do echo -n $i; done`  ./log-path_test.cpp.tmp
  ==5031==ERROR: Path is too long: 01234567...
  Segmentation Fault (core dumped)

The `SEGV` happens here:

  Thread 2 received signal SIGSEGV, Segmentation fault.
  [Switching to Thread 1 (LWP 1)]
  0x00000000 in ?? ()
  (gdb) where
  #0  0x00000000 in ?? ()
  #1  0x080a1e63 in __interceptor__exit (status=1)

  #2  0x08135ea8 in __sanitizer::internal__exit (exitcode=1)
      at /vol/gcc/src/llvm/llvm/local/projects/compiler-rt/lib/sanitizer_common/sanitizer_solaris.cc:139

when `__interceptor__exit` tries to call `__interception::real__exit` which
is `NULL` at this point because the interceptors haven't been initialized yet.

Ultimately, the problem lies elsewhere, however: `internal__exit` in
`sanitizer_solaris.cpp` calls `_exit` itself since there doesn't exit a
non-intercepted version in `libc`.  Using the `syscall` interface instead
isn't usually an option on Solaris because that interface isn't stable.
However, in the case of `SYS_exit` it can be used nonetheless: `SYS_exit`
has remained unchanged since at least Solaris 2.5.1 in 1996, and this is
what this patch does.

Tested on `amd64-pc-solaris2.11`.

Subject: [PATCH 161/544] [NFC][FE] Replace TypeSize with StorageUnitSize

On some targets like AIX, last bitfield size is not always equal to last
bitfield type size. Some bitfield like bool will have the same alignment
as [unsigned]. So we'd like to use a more general term `StorageUnit` to
replace type in this field.

Subject: [PATCH 163/544] RegAllocFast: Add extra DBG_VALUE for live out spills

This allows LiveDebugValues to insert the proper DBG_VALUEs in live
out blocks if a spill is inserted before the use of a
register. Previously, this would see the register use as the last
DBG_VALUE, even though the stack slot should be treated as the live
out value.

This avoids an lldb test regression when D52010 is re-applied.

Subject: [PATCH 167/544] [FE] Use preferred alignment instead of ABI alignment
 for complete object when applicable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On some targets, preferred alignment is larger than ABI alignment in some cases. For example,
on AIX we have special power alignment rules which would cause that. Previously, to support
those cases, we added a “PreferredAlignment” field in the `RecordLayout` to store the AIX
special alignment values in “PreferredAlignment” as the community suggested.

However, that patch alone is not enough. There are places in the Clang where `PreferredAlignment`
should have been used instead of ABI-specified alignment. This patch is aimed at fixing those
spots.

Subject: [PATCH 168/544] [mlir][Linalg] Generalize the logic to compute
 reassociation maps while folding tensor_reshape op.

While folding reshapes that introduce unit extent dims, the logic to
compute the reassociation maps can be generalized to handle some
corner cases, for example, when the folded shape still has unit-extent
dims but corresponds to folded unit extent dims of the expanded shape.

Subject: [PATCH 172/544] [PPC] Do not emit extswsli in 32BIT mode when using
 -mcpu=pwr9

It looks like in some circumstances when compiling with `-mcpu=pwr9` we create an EXTSWSLI node when which causes llc to fail. No such error occurs in pwr8 or lower.

This occurs in 32BIT AIX and BE Linux. the cause seems to be that the default return in combineSHL is to create an EXTSWSLI node.  Adding a check for whether we are in PPC64 before that fixes the issue.

Subject: [PATCH 173/544] [InstCombine] Add tests for 'partial' bswap patterns

As mentioned on PR47191, if we're bswap'ing some bytes and the zero'ing the remainder we can perform this as a bswap+mask which helps us match 'partial' bswaps as a first step towards folding into a more complex bswap pattern.

Subject: [PATCH 174/544] [NFC][regalloc] Make VirtRegAuxInfo part of allocator
 state

All the state of VRAI is allocator-wide, so we can avoid creating it
every time we need it. In addition, the normalization function is
allocator-specific. In a next change, we can simplify that design in
favor of just having it as a virtual member.

Subject: [PATCH 175/544] [DA][SDA] SyncDependenceAnalysis re-write

This patch achieves two things:
1. It breaks up the `join_blocks` interface between the SDA to the DA to
   return two separate sets for divergent loops exits and divergent,
disjoint path joins.
2. It updates the SDA algorithm to run in O(n) time and improves the
   precision on divergent loop exits.

This fixes `https://bugs.llvm.org/show_bug.cgi?id=46372` (by virtue of
the improved `join_blocks` interface) and revealed an imprecise expected
result in the `Analysis/DivergenceAnalysis/AMDGPU/hidden_loopdiverge.ll`
test.

Subject: [PATCH 178/544] [mlir][openacc] Remove -allow-unregistred-dialect
 from ops and invalid tests

Switch to a dummy op in the test dialect so we can remove the -allow-unregistred-dialect
on ops.mlir and invalid.mlir. Change after comment on D88272.

Subject: [PATCH 179/544] [llvm-exegesis] Add option to check the hardware
 support for a given feature before benchmarking.

This is mostly for the benefit of the LBR latency mode.
Right now, it performs no checking. If this is run on non-supported hardware, it will produce all zeroes for latency.

Subject: [PATCH 180/544] scudo: Make it thread-safe to set some runtime
 configuration flags.

Move some of the flags previously in Options, as well as the
UseMemoryTagging flag previously in the primary allocator, into an
atomic variable so that it can be updated while other threads are
running. Relaxed accesses are used because we only have the requirement
that the other threads see the new value eventually.

The code is set up so that the variable is generally loaded once per
allocation function call with the exception of some rarely used code
such as error handlers. The flag bits can generally stay in a register
during the execution of the allocation function which means that they
can be branched on with minimal overhead (e.g. TBZ on aarch64).

Subject: [PATCH 182/544] [asan][test] Several
 Posix/unpoison-alternate-stack.cpp fixes

`Posix/unpoison-alternate-stack.cpp` currently `FAIL`s on Solaris/i386.
Some of the problems are generic:

- `clang` warns compiling the testcase:

  compiler-rt/test/asan/TestCases/Posix/unpoison-alternate-stack.cpp:83:7: warning: nested designators are a C99 extension [-Wc99-designator]
        .sa_sigaction = signalHandler,
        ^~~~~~~~~~~~~
  compiler-rt/test/asan/TestCases/Posix/unpoison-alternate-stack.cpp:84:7: warning: ISO C++ requires field designators to be specified in declaration order; field '_funcptr' will be initialized after field 'sa_flags' [-Wreorder-init-list]
        .sa_flags = SA_SIGINFO | SA_NODEFER | SA_ONSTACK,
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  and some more instances.  This can all easily be avoided by initializing
  each field separately.

- The test `SEGV`s in `__asan_memcpy`.  The default Solaris/i386 stack size
  is only 4 kB, while `__asan_memcpy` tries to allocate either 5436
  (32-bit) or 10688 bytes (64-bit) on the stack.  This patch avoids this by
  requiring at least 16 kB stack size.

- Even without `-fsanitize=address` I get an assertion failure:

  Assertion failed: !isOnSignalStack(), file compiler-rt/test/asan/TestCases/Posix/unpoison-alternate-stack.cpp, line 117

  The fundamental problem with this testcase is that `longjmp` from a
  signal handler is highly unportable; XPG7 strongly warns against it and
  it is thus unspecified which stack is used when `longjmp`ing from a
  signal handler running on an alternative stack.

  So I'm `XFAIL`ing this testcase on Solaris.

Tested on `amd64-pc-solaris2.11` and `x86_64-pc-linux-gnu`.

Subject: [PATCH 183/544] [AArch64] Avoid pairing loads when the base reg is
 modified

When pairing loads, we should check if in between the two loads the
base register has been modified. If that is the case then avoid pairing
them because the second load actually loads from a different address.

Subject: [PATCH 184/544] [CodeGen] add test for NAN creation; NFC

This goes with the APFloat change proposed in
D88238.
This is copied from the MIPS-specific test in
builtin-nan-legacy.c to verify that the normal
behavior is correct on other targets without the
complication of an inverted quiet bit.

Subject: [PATCH 186/544] Fix interaction of `constinit` and `weak`.

We previously took a shortcut and said that weak variables never have
constant initializers (because those initializers are never correct to
use outside the variable). We now say that weak variables can have
constant initializers, but are never usable in constant expressions.

Subject: [PATCH 187/544] [OpenMP] Add Error Handling for Conflicting Pointer
 Sizes for Target Offload

Summary:
This patch adds an error to Clang that detects if OpenMP offloading is used
between two architectures with incompatible pointer sizes. This ensures that
the data mapping can be done correctly and solves an issue in code generation
generating the wrong size pointer.

Subject: [PATCH 188/544] [OpenMP] Replace OpenMP RTL Functions With
 OMPIRBuilder and OMPKinds.def

Summary:
Replace the OpenMP Runtime Library functions used in CGOpenMPRuntimeGPU
for OpenMP device code generation with ones in OMPKinds.def and use
OMPIRBuilder for generating runtime calls. This allows us to consolidate
more OpenMP code generation into the OMPIRBuilder. This patch also
invalidates specifying target architectures with conflicting pointer
sizes.

Subject: [PATCH 190/544] Exception support for basic block sections
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is part of the Propeller framework to do post link code layout optimizations. Please see the RFC here: https://groups.google.com/forum/#!msg/llvm-dev/ef3mKzAdJ7U/1shV64BYBAAJ and the detailed RFC doc here: https://github.com/google/llvm-propeller/blob/plo-dev/Propeller_RFC.pdf

This patch provides exception support for basic block sections by splitting the call-site table into call-site ranges corresponding to different basic block sections. Still all landing pads must reside in the same basic block section (which is guaranteed by the the core basic block section patch D73674 (ExceptionSection) ). Each call-site table will refer to the landing pad fragment by explicitly specifying @LPstart (which is omitted in the normal non-basic-block section case). All these call-site tables will share their action and type tables.

The C++ ABI somehow assumes that no landing pads point directly to LPStart (which works in the normal case since the function begin is never a landing pad), and uses LP.offset = 0 to specify no landing pad. In the case of basic block section where one section contains all the landing pads, the landing pad offset relative to LPStart could actually be zero. Thus, we avoid zero-offset landing pads by inserting a **nop** operation as the first non-CFI instruction in the exception section.

**Background on Exception Handling in C++ ABI**
https://github.com/itanium-cxx-abi/cxx-abi/blob/master/exceptions.pdf

Compiler emits an exception table for every function. When an exception is thrown, the stack unwinding library queries the unwind table (which includes the start and end of each function) to locate the exception table for that function.

The exception table includes a call site table for the function, which is used to guide the exception handling runtime to take the appropriate action upon an exception. Each call site record in this table is structured as follows:

| CallSite                       |  -->  Position of the call site (relative to the function entry)
| CallSite length           |  -->  Length of the call site.
| Landing Pad               |  -->  Position of the landing pad (relative to the landing pad fragment’s begin label)
| Action record offset  |  -->  Position of the first action record

The call site records partition a function into different pieces and describe what action must be taken for each callsite. The callsite fields are relative to the start of the function (as captured in the unwind table).

The landing pad entry is a reference into the function and corresponds roughly to the catch block of a try/catch statement. When execution resumes at a landing pad, it receives an exception structure and a selector value corresponding to the type of the exception thrown, and executes similar to a switch-case statement. The landing pad field is relative to the beginning of the procedure fragment which includes all the landing pads (@LPStart). The C++ ABI requires all landing pads to be in the same fragment. Nonetheless, without basic block sections, @LPStart is the same as the function @Start (found in the unwind table) and can be omitted.

The action record offset is an index into the action table which includes information about which exception types are caught.

**C++ Exceptions with Basic Block Sections**
Basic block sections break the contiguity of a function fragment. Therefore, call sites must be specified relative to the beginning of the basic block section. Furthermore, the unwinding library should be able to find the corresponding callsites for each section. To do so, the .cfi_lsda directive for a section must point to the range of call-sites for that section.
This patch introduces a new **CallSiteRange** structure which specifies the range of call-sites which correspond to every section:

  `struct CallSiteRange {
    // Symbol marking the beginning of the precedure fragment.
    MCSymbol *FragmentBeginLabel = nullptr;
    // Symbol marking the end of the procedure fragment.
    MCSymbol *FragmentEndLabel = nullptr;
    // LSDA symbol for this call-site range.
    MCSymbol *ExceptionLabel = nullptr;
    // Index of the first call-site entry in the call-site table which
    // belongs to this range.
    size_t CallSiteBeginIdx = 0;
    // Index just after the last call-site entry in the call-site table which
    // belongs to this range.
    size_t CallSiteEndIdx = 0;
    // Whether this is the call-site range containing all the landing pads.
    bool IsLPRange = false;
  };`

With N basic-block-sections, the call-site table is partitioned into N call-site ranges.

Conceptually, we emit the call-site ranges for sections sequentially in the exception table as if each section has its own exception table. In the example below, two sections result in the two call site ranges (denoted by LSDA1 and LSDA2) placed next to each other. However, their call-sites will refer to records in the shared Action Table. We also emit the header fields (@LPStart and CallSite Table Length) for each call site range in order to place the call site ranges in separate LSDAs. We note that with -basic-block-sections, The CallSiteTableLength will not actually represent the length of the call site table, but rather the reference to the action table. Since the only purpose of this field is to locate the action table, correctness is guaranteed.

Finally, every call site range has one @LPStart pointer so the landing pads of each section must all reside in one section (not necessarily the same section). To make this easier, we decide to place all landing pads of the function in one section (hence the `IsLPRange` field in CallSiteRange).

|  @LPStart                   |  --->  Landing pad fragment     ( LSDA1 points here)
| CallSite Table Length | ---> Used to find the action table.
| CallSites                     |
| …                                 |
| …                                 |
| @LPStart                    |  --->  Landing pad fragment ( LSDA2 points here)
| CallSite Table Length |
| CallSites                     |
| …                                 |
| …                                 |
…

|      Action Table          |

Subject: [PATCH 191/544] [lldb/ipv6] Support running lldb tests in an
 ipv6-only environment.

When running in an ipv6-only environment where `AF_INET` sockets are not available, many lldb tests (mostly gdb remote tests) fail because things like `127.0.0.1` don't work there.

Use `localhost` instead of `127.0.0.1` whenever possible, or include a fallback of creating `AF_INET6` sockets when `AF_INET` fails.

Subject: [PATCH 193/544] [lldb-vscode] Allow an empty 'breakpoints' field to
 clear breakpoints.

Per the DAP spec for SetBreakpoints [1], the way to clear breakpoints is: `To clear all breakpoint for a source, specify an empty array.`

However, leaving the breakpoints field unset is also a well formed request (note the `breakpoints?:` in the `SetBreakpointsArguments` definition). If it's unset, we have a couple choices:

1. Crash (current behavior)
2. Clear breakpoints
3. Return an error response that the breakpoints field is missing.

I propose we do (2) instead of (1), and treat an unset breakpoints field the same as an empty breakpoints field.

 there's no StructuredDataPlugin.

Also, use the StructuredData::Dump method to print the StructuredData if there

Subject: [PATCH 196/544] [libc++] Make sure we don't attempt to run
 check-cxx-abilist when libc++ doesn't define new/delete

That would make the test fail spuriously because we don't generate
an ABI list for that configuration.

Subject: [PATCH 201/544] [mlir][vector] First step of vector distribution
 transformation

This is the first of several steps to support distributing large vectors. This
adds instructions extract_map and insert_map that allow us to do incremental
lowering. Right now the transformation only apply to simple pointwise operation
with a vector size matching the multiplicity of the IDs used to distribute the
vector.
This can be used to distribute large vectors to loops or SPMD.

Subject: [PATCH 202/544] [NPM] Add target specific hook to add passes for New
 Pass Manager

The patch adds a new TargetMachine member "registerPassBuilderCallbacks" for targets to add passes to the pass pipeline using the New Pass Manager (similar to adjustPassManager for the Legacy Pass Manager).

Subject: [PATCH 203/544] [X86] Canonicalize (x > 1) ? x : 1 -> (x >= 1) ? x :
 1 for sign and unsigned to enable the use of test instructions for the
 compare.

This will be further canonicalized to a compare involving 0
which will enable the use of test instructions. Either using
cmovg for signed for cmovne for unsigned.

Fixes more case for PR47049

Subject: [PATCH 204/544] [asan][test] XFAIL Posix/no_asan_gen_globals.c on
 Solaris

`Posix/no_asan_gen_globals.c` currently `FAIL`s on Solaris:

  $ nm no_asan_gen_globals.c.tmp.exe | grep ___asan_gen_
  0809696a r .L___asan_gen_.1
  0809a4cd r .L___asan_gen_.2
  080908e2 r .L___asan_gen_.4
  0809a4cd r .L___asan_gen_.5
  0809a529 r .L___asan_gen_.7
  0809a4cd r .L___asan_gen_.8

As detailed in Bug 47607, there are two factors here:

- `clang` plays games by emitting some local labels into the symbol
  table.  When instead one uses `-fno-integrated-as` to have `gas` create
  the object files, they don't land in the objects in the first place.
- Unlike GNU `ld`, the Solaris `ld` doesn't support support
  `-X`/`--discard-locals` but instead relies on the assembler to follow its
  specification and not emit local labels.

Therefore this patch `XFAIL`s the test on Solaris.

Tested on `amd64-pc-solaris2.11` and `x86_64-pc-linux-gnu`.

Subject: [PATCH 208/544] [PDB] Merge types in parallel when using ghashing

This makes type merging much faster (-24% on chrome.dll) when multiple
threads are available, but it slightly increases the time to link (+10%)
when /threads:1 is passed. With only one more thread, the new type
merging is faster (-11%). The output PDB should be identical to what it
was before this change.

To give an idea, here is the /time output placed side by side:

    Commit to Disk:            1322 ms  | 1036 ms  -300ms
----------------------------------------- --------
Total Link Time:               8416 ms    5882 ms  -30% overall

The main source of the additional overhead in the single-threaded case
is the need to iterate all .debug$T sections up front to check which
type records should go in the IPI stream. See fillIsItemIndexFromDebugT.
With changes to the .debug$H section, we could pre-calculate this info
and eliminate the need to do this walk up front. That should restore
single-threaded performance back to what it was before this change.

This change will cause LLD to be much more parallel than it used to, and
for users who do multiple links in parallel, it could regress
performance. However, when the user is only doing one link, it's a huge
improvement. In the future, we can use NT worker threads to avoid
oversaturating the machine with work, but for now, this is such an
improvement for the single-link use case that I think we should land
this as is.

Algorithm
----------

Before this change, we essentially used a
DenseMap<GloballyHashedType, TypeIndex> to check if a type has already
been seen, and if it hasn't been seen, insert it now and use the next
available type index for it in the destination type stream. DenseMap
does not support concurrent insertion, and even if it did, the linker
must be deterministic: it cannot produce different PDBs by using
different numbers of threads. The output type stream must be in the same
order regardless of the order of hash table insertions.

In order to create a hash table that supports concurrent insertion, the
table cells must be small enough that they can be updated atomically.
The algorithm I used for updating the table using linear probing is
described in this paper, "Concurrent Hash Tables: Fast and General(?)!":
https://dl.acm.org/doi/10.1145/3309206

The GHashCell in this change is essentially a pair of 32-bit integer
indices: <sourceIndex, typeIndex>. The sourceIndex is the index of the
TpiSource object, and it represents an input type stream. The typeIndex
is the index of the type in the stream. Together, we have something like
a ragged 2D array of ghashes, which can be looked up as:
  tpiSources[tpiSrcIndex]->ghashes[typeIndex]

By using these side tables, we can omit the key data from the hash
table, and keep the table cell small. There is a cost to this: resolving
hash table collisions requires many more loads than simply looking at
the key in the same cache line as the insertion position. However, most
supported platforms should have a 64-bit CAS operation to update the
cell atomically.

To make the result of concurrent insertion deterministic, the cell
payloads must have a priority function. Defining one is pretty
straightforward: compare the two 32-bit numbers as a combined 64-bit
number. This means that types coming from inputs earlier on the command
line have a higher priority and are more likely to appear earlier in the
final PDB type stream than types from an input appearing later on the
link line.

After table insertion, the non-empty cells in the table can be copied
out of the main table and sorted by priority to determine the ordering
of the final type index stream. At this point, item and type records
must be separated, either by sorting or by splitting into two arrays,
and I chose sorting. This is why the GHashCell must contain the isItem
bit.

Once the final PDB TPI stream ordering is known, we need to compute a
mapping from source type index to PDB type index. To avoid starting over
from scratch and looking up every type again by its ghash, we save the
insertion position of every hash table insertion during the first
insertion phase. Because the table does not support rehashing, the
insertion position is stable. Using the array of insertion positions
indexed by source type index, we can replace the source type indices in
the ghash table cells with the PDB type indices.

Once the table cells have been updated to contain PDB type indices, the
mapping for each type source can be computed in parallel. Simply iterate
the list of cell positions and replace them with the PDB type index,
since the insertion positions are no longer needed.

Once we have a source to destination type index mapping for every type
source, there are no more data dependencies. We know which type records
are "unique" (not duplicates), and what their final type indices will
be. We can do the remapping in parallel, and accumulate type sizes and
type hashes in parallel by type source.

Lastly, TPI stream layout must be done serially. Accumulate all the type
records, sizes, and hashes, and add them to the PDB.

+/// Concurrent Hash Tables: Fast and General(?)!

+///
+/// This hash table is meant to be used in two phases:
+/// 1. concurrent insertions
+/// 2. concurrent reads
+/// It does not support lookup, deletion, or rehashing. It uses linear probing.
+///
+/// The paper describes storing a key-value pair in two machine words.
+/// Generally, the values stored in this map are type indices, and we can use
+/// those values to recover the ghash key from a side table. This allows us to
+/// shrink the table entries further at the cost of some loads, and sidesteps
+/// the need for a 128 bit atomic compare-and-swap operation.
+///
+/// During insertion, a priority function is used to decide which insertion
+/// should be preferred. This ensures that the output is deterministic. For
+/// ghashing, lower tpiSrcIdx values (earlier inputs) are preferred.

-/// A concurrent hash table for global type hashing. It is based on this paper:
-/// Concurrent Hash Tables: Fast and General(?)!
-/// https://dl.acm.org/doi/10.1145/3309206
-///
-/// This hash table is meant to be used in two phases:
-/// 1. concurrent insertions
-/// 2. concurrent reads
-/// It does not support lookup, deletion, or rehashing. It uses linear probing.
-///
-/// The paper describes storing a key-value pair in two machine words.
-/// Generally, the values stored in this map are type indices, and we can use
-/// those values to recover the ghash key from a side table. This allows us to
-/// shrink the table entries further at the cost of some loads, and sidesteps
-/// the need for a 128 bit atomic compare-and-swap operation.
-///
-/// During insertion, a priority function is used to decide which insertion
-/// should be preferred. This ensures that the output is deterministic. For
-/// ghashing, lower tpiSrcIdx values (earlier inputs) are preferred.

Subject: [PATCH 210/544] [mlir][Linalg] Add pattern to tile and fuse Linalg
 operations on buffers.

The pattern is structured similar to other patterns like
LinalgTilingPattern. The fusion patterns takes options that allows you
to fuse with producers of multiple operands at once.
- The pattern fuses only at the level that is known to be legal, i.e
  if a reduction loop in the consumer is tiled, then fusion should
  happen "before" this loop. Some refactoring of the fusion code is
  needed to fuse only where it is legal.
- Since the fusion on buffers uses the LinalgDependenceGraph that is
  not mutable in place the fusion pattern keeps the original
  operations in the IR, but are tagged with a marker that can be later
  used to find the original operations.

This change also fixes an issue with tiling and
distribution/interchange where if the tile size of a loop were 0 it
wasnt account for in these.

Subject: [PATCH 213/544] Re-land "[PDB] Merge types in parallel when using
 ghashing"

Stored Error objects have to be checked, even if they are success
values.

This reverts commit 8d250ac3cd48d0f17f9314685a85e77895c05351.
Relands commit 49b3459930655d879b2dc190ff8fe11c38a8be5f..

Original commit message:
-----------------------------------------

This makes type merging much faster (-24% on chrome.dll) when multiple
threads are available, but it slightly increases the time to link (+10%)
when /threads:1 is passed. With only one more thread, the new type
merging is faster (-11%). The output PDB should be identical to what it
was before this change.

To give an idea, here is the /time output placed side by side:

----------------------------------------- --------
Total Link Time:               8416 ms    5882 ms  -30% overall

The main source of the additional overhead in the single-threaded case
is the need to iterate all .debug$T sections up front to check which
type records should go in the IPI stream. See fillIsItemIndexFromDebugT.
With changes to the .debug$H section, we could pre-calculate this info
and eliminate the need to do this walk up front. That should restore
single-threaded performance back to what it was before this change.

This change will cause LLD to be much more parallel than it used to, and
for users who do multiple links in parallel, it could regress
performance. However, when the user is only doing one link, it's a huge
improvement. In the future, we can use NT worker threads to avoid
oversaturating the machine with work, but for now, this is such an
improvement for the single-link use case that I think we should land
this as is.

Algorithm
----------

Before this change, we essentially used a
DenseMap<GloballyHashedType, TypeIndex> to check if a type has already
been seen, and if it hasn't been seen, insert it now and use the next
available type index for it in the destination type stream. DenseMap
does not support concurrent insertion, and even if it did, the linker
must be deterministic: it cannot produce different PDBs by using
different numbers of threads. The output type stream must be in the same
order regardless of the order of hash table insertions.

In order to create a hash table that supports concurrent insertion, the
table cells must be small enough that they can be updated atomically.
The algorithm I used for updating the table using linear probing is
described in this paper, "Concurrent Hash Tables: Fast and General(?)!":
https://dl.acm.org/doi/10.1145/3309206

The GHashCell in this change is essentially a pair of 32-bit integer
indices: <sourceIndex, typeIndex>. The sourceIndex is the index of the
TpiSource object, and it represents an input type stream. The typeIndex
is the index of the type in the stream. Together, we have something like
a ragged 2D array of ghashes, which can be looked up as:
  tpiSources[tpiSrcIndex]->ghashes[typeIndex]

By using these side tables, we can omit the key data from the hash
table, and keep the table cell small. There is a cost to this: resolving
hash table collisions requires many more loads than simply looking at
the key in the same cache line as the insertion position. However, most
supported platforms should have a 64-bit CAS operation to update the
cell atomically.

To make the result of concurrent insertion deterministic, the cell
payloads must have a priority function. Defining one is pretty
straightforward: compare the two 32-bit numbers as a combined 64-bit
number. This means that types coming from inputs earlier on the command
line have a higher priority and are more likely to appear earlier in the
final PDB type stream than types from an input appearing later on the
link line.

After table insertion, the non-empty cells in the table can be copied
out of the main table and sorted by priority to determine the ordering
of the final type index stream. At this point, item and type records
must be separated, either by sorting or by splitting into two arrays,
and I chose sorting. This is why the GHashCell must contain the isItem
bit.

Once the final PDB TPI stream ordering is known, we need to compute a
mapping from source type index to PDB type index. To avoid starting over
from scratch and looking up every type again by its ghash, we save the
insertion position of every hash table insertion during the first
insertion phase. Because the table does not support rehashing, the
insertion position is stable. Using the array of insertion positions
indexed by source type index, we can replace the source type indices in
the ghash table cells with the PDB type indices.

Once the table cells have been updated to contain PDB type indices, the
mapping for each type source can be computed in parallel. Simply iterate
the list of cell positions and replace them with the PDB type index,
since the insertion positions are no longer needed.

Once we have a source to destination type index mapping for every type
source, there are no more data dependencies. We know which type records
are "unique" (not duplicates), and what their final type indices will
be. We can do the remapping in parallel, and accumulate type sizes and
type hashes in parallel by type source.

Lastly, TPI stream layout must be done serially. Accumulate all the type
records, sizes, and hashes, and add them to the PDB.

+/// Concurrent Hash Tables: Fast and General(?)!

+///
+/// This hash table is meant to be used in two phases:
+/// 1. concurrent insertions
+/// 2. concurrent reads
+/// It does not support lookup, deletion, or rehashing. It uses linear probing.
+///
+/// The paper describes storing a key-value pair in two machine words.
+/// Generally, the values stored in this map are type indices, and we can use
+/// those values to recover the ghash key from a side table. This allows us to
+/// shrink the table entries further at the cost of some loads, and sidesteps
+/// the need for a 128 bit atomic compare-and-swap operation.
+///
+/// During insertion, a priority function is used to decide which insertion
+/// should be preferred. This ensures that the output is deterministic. For
+/// ghashing, lower tpiSrcIdx values (earlier inputs) are preferred.

Subject: [PATCH 214/544] [flang] Semantic analysis for FINAL subroutines

Represent FINAL subroutines in the symbol table entries of
derived types.  Enforce constraints.  Update tests that have
inadvertent violations or modified messages.  Added a test.

The specific procedure distinguishability checking code for generics
was used to enforce distinguishability of FINAL procedures.
(Also cleaned up some confusion and redundancy noticed in the
type compatibility infrastructure while digging into that area.)

From 55cff5b288650f0ce814c3c85041852bbed554b8 Mon Sep 17 00:00:00 2001

Subject: [PATCH 215/544] [OpenMP][libomptarget] make omp_get_initial_device
 5.1 compliant

OpenMP 5.1 defines omp_get_initial_device to return the same value as omp_get_num_devices.
Since this change is also 5.0 compliant, no versioning is needed.

Differential Revision: https://reviews.llvm.org/D88149

Subject: [PATCH 216/544] [OpenMP][OMPT] Update OMPT tests for newly added GOMP
 interface patches

This patch updates the expected results for the GOMP interface patches: D87267, D87269, and D87271.
The taskwait-depend test is changed to really use taskwait-depend and copied to an task_if0-depend test.

To pass the tests, the handling of the return address was fixed.

Subject: [PATCH 219/544] Patch IEEEFloat::isSignificandAllZeros and
 IEEEFloat::isSignificandAllOnes (bug 34579)

Patch IEEEFloat::isSignificandAllZeros and IEEEFloat::isSignificandAllOnes to behave correctly in the case that the size of the significand is a multiple of the width of the integerParts making up the significand.

The patch to IEEEFloat::isSignificandAllOnes fixes bug 34579, and the patch to IEEE:Float:isSignificandAllZeros fixes the unit test "APFloatTest.x87Next" I added here. I have included both in this diff since the changes are very similar.

Subject: [PATCH 220/544] [OpenMP][libarcher] Allow all possible argument
 separators in TSAN_OPTIONS

Currently, the parser used to tokenize the TSAN_OPTIONS in libomp uses
only spaces as separators, even though TSAN in compiler-rt supports
other separators like ':' or ','.
CTest uses ':' to separate sanitizer options by default.
The documentation for other sanitizers mentions ':' as separator,
but TSAN only lists spaces, which is probably where this mismatch originated.

Subject: [PATCH 221/544] [ARM] Add missing target for Arm neon test case.

This is a follow-up from https://reviews.llvm.org/D61717. Where Richard
described the issue with compiling arm_neon.h under
-flax-vector-conversions=none. It looks like the example reproducer does
actually work but what was missing was a test entry for that target.

Subject: [PATCH 222/544] [AArch64][GlobalISel] NFC: Refactor G_FCMP selection
 code

Refactor this so it's similar to the existing integer comparison code.

Also add some missing 64-bit testcases to select-fcmp.mir.

Refactoring to prep for improving selection for G_FCMP-related conditional
branches etc.

Subject: [PATCH 223/544] [lldb] Make TestGuiBasicDebug more lenient

Matt's change to the register allocator in 89baeaef2fa9 changed where we
end up after the `finish`. Before we'd end up on line 4.

* thread #1, queue = 'com.apple.main-thread', stop reason = step out
Return value: (int) $0 = 1
    frame #0: 0x0000000100003f7d a.out`main(argc=1, argv=0x00007ffeefbff630) at main.c:4:3
   1    extern int func();
   2
   3    int main(int argc, char **argv) {
-> 4      func(); // Break here
   5      func(); // Second
   6      return 0;
   7    }

Now, we end up on line 5.

* thread #1, queue = 'com.apple.main-thread', stop reason = step out
Return value: (int) $0 = 1

    frame #0: 0x0000000100003f8d a.out`main(argc=1, argv=0x00007ffeefbff630) at main.c:5:3
   2
   3    int main(int argc, char **argv) {
   4      func(); // Break here
-> 5      func(); // Second
   6      return 0;
   7    }

Given that this is not expected stable to be stable I've made the test a
bit more lenient to accept both scenarios.

Subject: [PATCH 224/544] [flang] Allow record advancement in external
 formatted sequential READ

The '/' control edit descriptor causes a runtime crash for an
external formatted sequential READ because the AdvanceRecord()
member function for external units implemented only the tasks
to finish reading the current record.  Split those out into
a new FinishReadingRecord() member function, call that instead
from EndIoStatement(), and change AdvanceRecord() to both
finish reading the current record and to begin reading the next
one.

Subject: [PATCH 225/544] [AArch64][GlobalISel] Add some more legal types for
 G_PHI, G_IMPLICIT_DEF, G_FREEZE.

Also use this opportunity start to clean up the mess of vector type lists we
have in the LegalizerInfo. Unfortunately since the legalizer rule builders require
std::initializer_list objects as parameters we can't programmatically generate the
type lists.

Subject: [PATCH 226/544] [WholeProgramDevirt][NewPM] Add NPM testing path to
 match legacy pass

The legacy pass's default constructor sets UseCommandLine = true and
goes down a separate testing route. Match that in the NPM pass.

This fixes all tests in llvm/test/Transforms/WholeProgramDevirt under NPM.

Subject: [PATCH 228/544] [lld][WebAssembly] Allow exporting of mutable globals

In particular allow explict exporting of `__stack_pointer` but
exclud this from `--export-all` to avoid requiring the mutable
globals feature whenenve `--export-all` is used.

This uncovered a bug in populateTargetFeatures regarding checking
if the mutable-globals feature is allowed.

The current implementation uses a fold expression to add all of the operations at once. This is really nice, but apparently the lifetime of each of the AbstractOperation instances is for the entire expression which may lead to a stack overflow for large numbers of operations. This splits the method in two to allow for the lifetime of the AbstractOperation to be properly scoped.

Subject: [PATCH 233/544] [flang][msvc] Avoid ReferenceVariantBase ctor
 ambiguity. NFC.

Msvc reports the following error when a ReferenceVariantBase is constructed using an r-value reference or instantiated as std::vector template parameter.  The error message is:
```
PFTBuilder.h(59,1): error C2665: 'std::variant<...>::variant': none of the 2 overloads could convert all the argument types
variant(1248,1): message : could be 'std::variant<...>::variant(std::variant<...> &&) noexcept(false)'
variant(1248,1): message : or       'std::variant<...>::variant(const std::variant<...> &) noexcept(false)'
PFTBuilder.h(59,1): message : while trying to match the argument list '(common::Reference<lower::pft::ReferenceVariantBase<false,...>>)'
```

Work around the ambiguity by only taking `common::Reference` arguments in the constructor. That is, conversion to common::Reference has to be done be the caller instead of being done inside the ctor. Unfortunately, with this change clang/gcc (but not msvc) insist on that the ReferenceVariantBase is stored in a `std::initializer_list`-initialized variable before being used, like being passed to a function or returned.

This patch is part of the series to make flang compilable with MS Visual Studio <http://lists.llvm.org/pipermail/flang-dev/2020-July/000448.html>.

Subject: [PATCH 234/544] [WebAssembly] New-style command support

This adds support for new-style command support. In this mode, all exports
are considered command entrypoints, and the linker inserts calls to
`__wasm_call_ctors` and `__wasm_call_dtors` for all such entrypoints.

This enables support for:

 - Command entrypoints taking arguments other than strings and return values
   other than `int`.
 - Multicall executables without requiring on the use of string-based
   command-line arguments.

This new behavior is disabled when the input has an explicit call to
`__wasm_call_ctors`, indicating code not expecting new-style command
support.

This change does mean that wasm-ld no longer supports DCE-ing the
`__wasm_call_ctors` function when there are no calls to it. If there are no
calls to it, and there are ctors present, we assume it's wasm-ld's job to
insert the calls. This seems ok though, because if there are ctors present,
the program is expecting them to be called. This change affects the
init-fini-gc.ll test.

Subject: [PATCH 235/544] [flang][msvc] Workaround 'forgotten' symbols in
 FoldOperation. NFC.

This resolves an issue where the Microsoft compiler 'forgets' symbols when using constexpr in a lambda in a templated function. The symbols are:

1. The implicit lambda captures `context` and `convert`. Fix by making them explicit captures. The error message was:
```
fold-implementation.h(1220): error C2065: 'convert': undeclared identifier
```

2. The function template argument FROMCAT. Fix by storing it in a temporary constexpr variable inside the function. The error message was:
```
fold-implementation.h(1216): error C2065: 'FROMCAT': undeclared identifier
```

This patch is part of the series to make flang compilable with MS Visual Studio <http://lists.llvm.org/pipermail/flang-dev/2020-July/000448.html>.

Subject: [PATCH 236/544] [APFloat] Improve asserts in isSignificandAllOnes and
 isSignificandAllZeros so they protect shift operations from undefined
 behavior.

For example, the assert in isSignificandAllZeros allowed NumHighBits
to be integerPartWidth. But since it is used directly as a shift amount
it must be less than integerPartWidth.

Subject: [PATCH 237/544] [ELF] --wrap: don't unnecessarily expose __real_

The routing rules are:

sym -> __wrap_sym
__real_sym -> sym

__wrap_sym and sym are routing targets, so they need to be exposed to the symbol
table. __real_sym is not and can be eliminated if not used by regular object.

Subject: [PATCH 238/544] Revert "[llvm-exegesis] Add option to check the
 hardware support for a given feature before benchmarking."

This reverts commit 4fcd1a8e6528ca42fe656f2745e15d2b7f5de495 as
`llvm/test/tools/llvm-exegesis/X86/lbr/mov-add.s` failed on hosts
without LBR supported if the build has LIBPFM enabled. On that host,
`perf_event_open` fails with `EOPNOTSUPP` on LBR config. That change's
basic assumption

> If this is run on a non-supported hardware, it will produce all zeroes for latency.

could not stand as `perf_event_open` system call will fail if the
underlying hardware really don't have LBR supported.

 Making a Major Change

Subject: [PATCH 243/544] [AVR] fix interrupt stack pointer restoration

This patch fixes a corruption of the stack pointer and several registers in any AVR interrupt with non-empty stack frame.  Previously, the callee-saved registers were popped before restoring the stack pointer, causing the pointer math to use the wrong base value while also corrupting the caller's register.  This change fixes the code to restore the stack pointer last before exiting the interrupt service routine.

Subject: [PATCH 248/544] [ORC][examples] Remove ThinLtoJIT example after
 LLJITWithThinLTOSummaries landed in OrcV2Examples

The ThinLtoJIT example was aiming to utilize ThinLTO summaries and concurrency in ORC for speculative compilation. The latter is heavily dependent on asynchronous task scheduling which is probably done better out-of-tree with a mature library like Boost-ASIO. The pure utilization of ThinLTO summaries in ORC is demonstrated in OrcV2Examples/LLJITWithThinLTOSummaries.

Subject: [PATCH 249/544] [ORC][examples] Temporarily remove
 LLJITWithChildProcess until ORC TPC lands

This solves a phase ordering problem: OrcV2 remote process support depends on OrcV2 removable code, OrcV2 removable code depends on OrcV1 removal, OrcV1 removal depends on LLJITWithChildProcess migration, and LLJITWithChildProcess migration depends on OrcV2 TargetProcessControl support.

Before deciding to insert a [W|D]LSTP, check that defining LR with
the element count won't affect any other instructions that should be
taking the iteration count.

Subject: [PATCH 252/544] [NFC] Iterate across an explicit list of scalable
 MVTs when driving setOperationAction.

Iterating across all of integer_scalable_vector_valuetypes seems
wasteful when there's only a handful we care about.

Also removes some rouge whitespace.

Subject: [PATCH 253/544] [SVE][CodeGen] Legalisation of integer -> floating
 point conversions

Splitting the operand of a scalable [S|U]INT_TO_FP results in a
concat_vectors operation where the operands are unpacked FP
scalable vectors (e.g. nxv2f32).
This patch adds custom lowering of concat_vectors which
checks that the number of operands is 2, and isel patterns
to match concat_vectors of scalable FP types with uzp1.

Subject: [PATCH 255/544] [SCEV] Prove implicaitons via AddRec start

If we know that some predicate is true for AddRec and an invariant
(w.r.t. this AddRec's loop), this fact is, in particular, true on the first
iteration. We can try to prove the facts we need using the start value.

The motivating example is proving things like
```
  isImpliedCondOperands(>=, X, 0, {X,+,-1}, 0}
```

Subject: [PATCH 256/544] [mlir][Linalg] Fix ASAN bug

```
 LinalgTilingOptions &setTileSizes(ValueRange ts)
```
makes it all too easy to create stack-use-after-return errors.

In particular, c694588fc52a8845174fee06ad0bcfa338e87816 introduced one such issue.

Instead just take a copy in the lambda and be done with it.

Subject: [PATCH 257/544] [SVE][CodeGen] Lower scalable fp_extend & fp_round
 operations

This patch adds FP_EXTEND_MERGE_PASSTHRU & FP_ROUND_MERGE_PASSTHRU
ISD nodes, used to lower scalable vector fp_extend/fp_round operations.
fp_round has an additional argument, the 'trunc' flag, which is an integer of zero or one.

This also fixes a warning introduced by the new tests added to sve-split-fcvt.ll,
resulting from an implicit TypeSize -> uint64_t cast in SplitVecOp_FP_ROUND.

Subject: [PATCH 258/544] [CFGuard] Add address-taken IAT tables and delay-load
 support

This patch adds support for creating Guard Address-Taken IAT Entry Tables (.giats$y sections) in object files, matching the behavior of MSVC. These contain lists of address-taken imported functions, which are used by the linker to create the final GIATS table.
Additionally, if any DLLs are delay-loaded, the linker must look through the .giats tables and add the respective load thunks of address-taken imports to the GFIDS table, as these are also valid call targets.

This test seems to randomly fail on Linux machines. It's only one part of the
test failing randomly, so let's just skip it instead of reverting the whole
patch (again).

Subject: [PATCH 264/544] [LoopFlatten] Add a loop-flattening pass

This is a simple pass that flattens nested loops.  The intention is to optimise
loop nests like this, which together access an array linearly:

  for (int i = 0; i < N; ++i)
    for (int j = 0; j < M; ++j)
      f(A[i*M+j]);

into one loop:

  for (int i = 0; i < (N*M); ++i)
    f(A[i]);

It can also flatten loops where the induction variables are not used in the
loop. This can help with codesize and runtime, especially on simple cpus
without advanced branch prediction.

This is only worth flattening if the induction variables are only used in an
expression like i*M+j. If they had any other uses, we would have to insert a
div/mod to reconstruct the original values, so this wouldn't be profitable.

This partially fixes PR40581 as this pass triggers on one of the two cases. I
will follow up on this to learn LoopFlatten a few more (small) tricks. Please
note that LoopFlatten is not yet enabled by default.

Patch by Oliver Stannard, with minor tweaks from Dave Green and myself.

Subject: [PATCH 266/544] [Archive] Don't throw away errors for malformed
 archive members

When adding an archive member with a problem, e.g. a new bitcode with an
old archiver, containing an unsupported attribute, or an ELF file with a
malformed symbol table, the archiver would throw away the error and
simply add the member to the archive without any symbol entries. This
meant that the resultant archive could be silently unusable when not
using --whole-archive, and result in unexpected undefined symbols.

This change fixes this issue by addressing two FIXMEs and only throwing
away not-an-object errors. However, this meant that some LLD tests which
didn't need symbol tables and were using invalid members deliberately to
test the linker's malformed input handling no longer worked, so this
patch also stops the archiver from looking for symbols in an object if
it doesn't require a symbol table, and updates the tests accordingly.

Differential Revision: https://reviews.llvm.org/D88288

Subject: [PATCH 271/544] [compiler-rt][cmake][powerpc] Remove TEST_BIG_ENDIAN
 from base-config-ix.cmake

It's actually not safe to call TEST_BIG_ENDIAN here, since we may be
running from the builtins build (i.e builtins-config-ix) context where
TEST_COMPILE_ONLY  is set since without builtins already built we may
fail to link, and TEST_BIG_ENDIAN internally performs tests which may
fail to link without builtins.

Fortunately powerpc is the only target that uses this information here and
we actually already know the whether we are targeting the LE variant due
to earlier macro checks, so we can simply this to remove our reliance on
TEST_BIG_ENDIAN.

Subject: [PATCH 272/544] [clangd] clangd --check: standalone diagnosis of
 common problems

This is a tool to simply parse a file as clangd would, and run some
common features (code actions, go-to-definition, hover) in an attempt to
trigger or reproduce crashes, error diagnostics, etc.

This is easier and more predictable than loading the file in clangd, because:
 - there's no editor/plugin variation to worry about
 - there's no accidental variation of user behavior or other extraneous requests
 - we trigger features at every token, rather than guessing
 - everything is synchronoous, logs are easier to reason about
 - it's easier to (get users to) capture logs when running on the command-line

This is a fairly lightweight variant of this idea.
We could do a lot more with it, and maybe we should.
But I can't in the near future, and experience will tell us if we made
the right tradeoffs and if it's worth investing further.

Subject: [PATCH 273/544] Migrate Declarators to use the List API

After this change all nodes that have a delimited-list are using the
`List` API.

Implementation details:
Let's look at a declaration with multiple declarators:
`int a, b;`
To generate a declarator list node we need to have the range of
declarators: `a, b`:
However, the `ClangAST` actually stores them as separate declarations:
`int a   ;`
`int    b;`
We solve that by appropriately marking the declarators on each separate
declaration in the `ClangAST` and then for the final declarator `int
b`, shrinking its range to fit to the already marked declarators.

Differential Revision: https://reviews.llvm.org/D88403

Subject: [PATCH 274/544] Revert "[clangd] clangd --check: standalone diagnosis
 of common problems"

This reverts commit 79fbcbff41734e3d07e6200d33c3e40732dfae6a.

The fallback command fails to parse for the test files if there's no
compile_commands.json in the tree.

-// Many basic problems can occur processing a file in clangd, e.g.:
-//  - system includes are not found
-//  - crash when indexing its AST
-// clangd --check provides a simplified, isolated way to reproduce these,
-// with no editor, LSP, threads, background indexing etc to contend with.
-//
-// One important use case is gathering information for bug reports.
-// Another is reproducing crashes, and checking which setting prevent them.
-//
-// It simulates opening a file (determining compile command, parsing, indexing)
-// and then running features at many locations.
-//
-// Currently it adds some basic logging of progress and results.
-// We should consider extending it to also recognize common symptoms and
-// recommend solutions (e.g. standard library installation issues).

Subject: [PATCH 275/544] Reland [clangd] clangd --check: standalone diagnosis
 of common problems

This reverts commit 30d07b14a274f075a01d201ad59723ca1a4a9b57.

Test failures have (hopefully) been fixed.

Subject: [PATCH 281/544] [clang][opencl][codegen] Remove the insertion of
 `correctly-rounded-divide-sqrt-fp-math` fn-attr.

- `-cl-fp32-correctly-rounded-divide-sqrt` is already handled in a
  per-instruction manner by annotating the accuracy required. There's no
  need to add that fn-attr. So far, there's no in-tree backend handling
  that attr and that OpenCL specific option.
- In case that out-of-tree backends are broken, this change could be
  reverted if those backends could not be fixed.

Subject: [PATCH 282/544] [InstCombine] collectBitParts - convert to use
 PatterMatch matchers and avoid IntegerType casts.

Make sure we're using getScalarSizeInBits instead of cast<IntegerType> to get Type bit widths.

This is preliminary cleanup before we can start adding vector support to the bswap/bitreverse (element level) matching.

Subject: [PATCH 283/544] [AArch64] Remove a duplicate call to setHasWinCFI.
 NFCI.

The function already has a cleanup scope that calls the same whenever
the function is exited. When reading the code, seeing that this return
codepath has an explicit call while other return paths lack it is
confusing.

In the hypothetical case of a function having a prologue that
set the HasWinCFI flag in the MF, but the epilogue containing no
WinCFI instructions, the HasWinCFI flag in the MF would end up reset back
to false.

Subject: [PATCH 284/544] [AArch64] Don't merge sp decrement into later stores
 when using WinCFI

This matches the corresponding existing case in
AArch64LoadStoreOpt::findMatchingUpdateInsnForward.

Both cases could also be modified to check
MBBI->getFlag(FrameSetup/FrameDestroy) instead of forbidding any
optimization involving SP, but the effect is probably pretty much
the same.

Subject: [PATCH 285/544] [clangd] Split DecisionForest Evaluate() into one
 func per tree.

This allows us MSAN to instrument this function. Previous version is not
instrumentable due to it shear volume.

Subject: [PATCH 286/544] Reland  rG4fcd1a8e6528:[llvm-exegesis] Add option to
 check the hardware support for a given feature before benchmarking.

This is mostly for the benefit of the LBR latency mode.
Right now, it performs no checking. If this is run on non-supported hardware, it will produce all zeroes for latency.

      Differential Revision: https://reviews.llvm.org/D85254

New change: Updated lit.local.cfg to use pass the right argument to llvm-exegesis to actually request the LBR mode.

Subject: [PATCH 288/544] [runtimes] Remove TOOLCHAIN_TOOLS specialization

https://reviews.llvm.org/D88310 fixed the AIX issue in LLVMExternalProjectUtils,
so we shouldn't need the workaround in the runtimes build anymore. I'm
reverting it because it prevents the target-specific tool selection in
LLVMExternalProjectUtils from taking effect, which we rely on for our
runtimes builds.

Subject: [PATCH 289/544] [NFC] Let (MC)Register APIs check isStackSlot

The user is expected to make the isStackSlot check before calling isPhysicalRegister
or isVirtualRegister. The APIs assert otherwise. We can improve the usability
of these APIs by carrying out the check in the 2 APIs: they become a
complete "source of truth" and remove an extra responsibility from the
user.

Subject: [PATCH 290/544] [flang] Add checks for misuse of formatted I/O APIs
 in unformatted I/O statement

Add checking to I/O statement APIs to catch cases where the formatted
I/O data item transfer routines like OutputInteger64 are being
incorrectly used for unformatted I/O, which should use the
unformatted block or descriptor-based data item interfaces.

Subject: [PATCH 291/544] Allow to specify macro names for
 android-comparison-in-temp-failure-retry

Some projects do not use the TEMP_FAILURE_RETRY macro but define their
own one, as not to depend on glibc / Bionic details. By allowing the
user to override the list of macros, these projects can also benefit
from this check.

Subject: [PATCH 292/544] [flang] Fix INQUIRE of access and formatting
 possibilities

Don't give false positives from INQUIRE about possible
access mode changes on connected units.  DIRECT and SEQUENTIAL
cannot be intermixed, apart from allowing DIRECT on a SEQUENTIAL
file with fixed-size records and positioning.  Nor can
FORMATTED and UNFORMATTED be interchanged.  On unconnected
files, the best that we can do is "UNKNOWN".

This is a temporary workaround until the new/delete situation is made
better (i.e. we don't include new/delete in both libc++ and libc++abi
by default).

Subject: [PATCH 294/544] [flang] Fix WRITE after BACKSPACE

A WRITE to an unformatted sequential variable-length unit after
a BACKSPACE needs to forget its previous knowledge of the length
of the record that's about to be overwritten, and a BACKSPACE
after an ENDFILE or at the start of the file needs to be a no-op.

Subject: [PATCH 295/544] Reland No.3: Add new hidden option -print-changed
 which only reports changes to IR

A new hidden option -print-changed is added along with code to support
printing the IR as it passes through the opt pipeline in the new pass
manager. Only those passes that change the IR are reported, with others
only having the banner reported, indicating that they did not change the
IR, were filtered out or ignored. Filtering of output via the
-filter-print-funcs is supported and a new supporting hidden option
-filter-passes is added. The latter takes a comma separated list of pass
names and filters the output to only show those passes in the list that
change the IR. The output can also be modified via the -print-module-scope
function.

The code introduces an abstract template base class that generalizes the
comparison of IRs that takes an IR representation as template parameter.
Derived classes provide overrides that provide an event based API
for generalized reporting of IRs as they are changed in the opt pipeline
through the new pass manager.

The first of several instantiations is provided that prints the IR
in a form similar to that produced by -print-after-all with the above
mentioned filtering capabilities. This version, and the others to
follow will be introduced at the upcoming developer's conference.

Subject: [PATCH 297/544] [DSE] Look through memory PHI arguments when removing
 noop stores in MSSA.

Summary:
Adds support for "following" memory through MSSA PHI arguments. This will help catch more noop stores that exist between blocks.

Originally part of D79391.

Subject: [PATCH 299/544] [AST] do not error on APFloat invalidOp in default
 mode

If FP exceptions are ignored, we should not error out of compilation
just because APFloat indicated an exception.
This is required as a preliminary step for D88238
which changes APFloat behavior for signaling NaN convert() to set
the opInvalidOp exception status.

Currently, there is no way to trigger this error because convert()
never sets opInvalidOp. FP binops that set opInvalidOp also create
a NaN, so the path to checkFloatingPointResult() is blocked by a
different diagnostic:

  // [expr.pre]p4:
  //   If during the evaluation of an expression, the result is not
  //   mathematically defined [...], the behavior is undefined.
  // FIXME: C++ rules require us to not conform to IEEE 754 here.
  if (LHS.isNaN()) {
    Info.CCEDiag(E, diag::note_constexpr_float_arithmetic) << LHS.isNaN();
    return Info.noteUndefinedBehavior();
  }
  return checkFloatingPointResult(Info, E, St);

Add Thread Local Storage support for the 34 bit relocation R_PPC64_GOT_TLSGD_PCREL34 used in General Dynamic.

The compiler will produce code that looks like:
```
pla r3, x@got@tlsgd@pcrel            R_PPC64_GOT_TLSGD_PCREL34
bl __tls_get_addr@notoc(x@tlsgd)     R_PPC64_TLSGD
                                     R_PPC64_REL24_NOTOC
```
LLD should be able to correctly compute the relocation for  R_PPC64_GOT_TLSGD_PCREL34 as well as do the following two relaxations where possible:
General Dynamic to Local Exec:
```
paddi r3, r13, x@tprel
nop
```
and General Dynamic to Initial Exec:
```
pld r3, x@got@tprel@pcrel
add r3, r3, r13
```
Note:
This patch adds support for the PC Relative (no TOC) version of General Dynamic on top of the existing support for the TOC version of General Dynamic.
The ABI does not provide any way to tell by looking only at the relocation `R_PPC64_TLSGD` when it is being used in a TOC instruction sequence or and when it is being used in a no TOC sequence. The TOC sequence should always be 4 byte aligned. This patch adds one to the offset of the relocation when it is being used in a no TOC sequence. In this way LLD can tell by looking at the alignment of the offset of `R_PPC64_TLSGD` whether or not it is being used as part of a TOC or no TOC sequence.

Subject: [PATCH 305/544] [APFloat] convert SNaN to QNaN in convert() and raise
 Invalid signal

This is an alternate fix (see D87835) for a bug where a NaN constant
gets wrongly transformed into Infinity via truncation.
In this patch, we uniformly convert any SNaN to QNaN while raising
'invalid op'.
But we don't have a way to directly specify a 32-bit SNaN value in LLVM IR,
so those are always encoded/decoded by calling convert from/to 64-bit hex.

See D88664 for a clang fix needed to allow this change.

Differential Revision: https://reviews.llvm.org/D88238

Subject: [PATCH 306/544] [CMake] Use -isystem flag to access libc++ headers

This is a partial revert of D62155. Rather than copying libc++ headers
into the build directory to be later overwritten by the final headers,
use -isystem flag to access libc++ headers during CMake checks. This
should address the occasional flake we've seen, especially on Windows
builders where CMake fails to overwrite __config with the final version.

Subject: [PATCH 307/544] [InstCombine] Fix select operand simplification with
 undef (PR47696)

When replacing X == Y ? f(X) : Z with X == Y ? f(Y) : Z, make sure
that Y cannot be undef. If it may be undef, we might end up picking
a different value for undef in the comparison and the select
operand.

Subject: [PATCH 309/544] [lit] Fix Python 2/3 compat in new winreg search code

This should fix the test failures on the clang win64 bot:
http://lab.llvm.org:8011/builders/clang-x64-windows-msvc/builds/18830
It has been red since Sept 23-ish.

This was subtle to debug. Windows has 'find' and 'sort' utilities in
C:\Windows\system32, but they don't support all the same flags as the
coreutils programs. I configured the buildbot above with Python 2.7
64-bit (hey, it was set up in 2016). When I installed git for Windows, I
opted to add all the Unix utilities that come with git to the system
PATH. This is *almost* enough to make the LLVM tests pass, but not
quite, because if you use the system PATH, the Windows version of find
and sort come first, but the tests that use diff, cmp, etc, will all
pass. So only a handful of tests will fail, and with cryptic error
messages.

The code changed in this CL doesn't work with Python 2. Before
Python 3.2, the winreg.OpenKey function did not accept the `access=`
keyword argument, the caller was required to pass an unused `reserved`
positional argument of 0. The try/except/pass around the OpenKey
operation masked this usage error in Python 2.

Further, the result of the registry operation has to be converted from
unicode to add it to the environment, but that was incidental.

 R_PPC64_GOT_TLSGD_PCREL34 used in TLS General Dynamic

Add Thread Local Storage support for the 34 bit relocation R_PPC64_GOT_TLSGD_PCREL34 used in General Dynamic.

The compiler will produce code that looks like:
```
pla r3, x@got@tlsgd@pcrel            R_PPC64_GOT_TLSGD_PCREL34
bl __tls_get_addr@notoc(x@tlsgd)     R_PPC64_TLSGD
                                     R_PPC64_REL24_NOTOC
```
LLD should be able to correctly compute the relocation for  R_PPC64_GOT_TLSGD_PCREL34 as well as do the following two relaxations where possible:
General Dynamic to Local Exec:
```
paddi r3, r13, x@tprel
nop
```
and General Dynamic to Initial Exec:
```
pld r3, x@got@tprel@pcrel
add r3, r3, r13
```
Note:
This patch adds support for the PC Relative (no TOC) version of General Dynamic on top of the existing support for the TOC version of General Dynamic.
The ABI does not provide any way to tell by looking only at the relocation `R_PPC64_TLSGD` when it is being used in a TOC instruction sequence or and when it is being used in a no TOC sequence. The TOC sequence should always be 4 byte aligned. This patch adds one to the offset of the relocation when it is being used in a no TOC sequence. In this way LLD can tell by looking at the alignment of the offset of `R_PPC64_TLSGD` whether or not it is being used as part of a TOC or no TOC sequence.

Subject: [PATCH 312/544] [clang][Sema] Fix PR47676: Handle dependent AltiVec
 C-style cast

Fix premature decision in the presence of type-dependent expression
operands on whether AltiVec vector initializations from single
expressions are "splat" operations.

Verify that the instantiation is able to determine the correct cast
semantics for both the scalar type and the vector type case.

Note that, because the change only affects the single-expression
case (and the target type is an AltiVec-style vector type), the
replacement of a parenthesized list with a parenthesized expression
does not change the semantics of the program in a program-observable
manner.

Subject: [PATCH 314/544] [AArch64][GlobalISel] Use custom legalization for
 G_TRUNC for v8i8 vectors.

Truncating to v8i8 is a case where we want to split the source but also generate
intermediate truncates to reduce the size of the source vector before truncating
down to v8i8. This implements the same strategy as what SelectionDAG does, but
I'm not certain where if anywhere in generic code it should live.

Use it for legalization of v8s8 = G_ICMP v8s32.

Subject: [PATCH 315/544] libclc: Use find_package to find Python 3 and require
 it

The script's shebang wants Python 3, so we use FindPython3. The
original code didn't work when an unversioned python was not available.
This is explicitly allowed in PEP 394. ("Distributors may choose to set
the behavior of the python command as follows: python2, python3, not
provide python command, allow python to be configurable by an end user
or a system administrator.")

Also I think it's actually required, so let the configuration fail if we
can't find it.

Lastly remove the shebang, since the script is only run via interpreter
and doesn't have the executable bit set anyway.

Subject: [PATCH 319/544] [LLD][COFF] Fix crash with /summary and PCH input
 files

Before this patch /summary was crashing with some .PCH.OBJ files, because tpiMap[srcIdx++] was reading at the wrong location. When the TpiSource depends on a .PCH.OBJ file, the types should be offset by the previously merged PCH.OBJ set of indices.

Subject: [PATCH 325/544] [AArch64][GlobalISel] Use emitTestBit in selection
 for G_BRCOND

Partially refactoring, partially fixing a bug.

- We shouldn't use TB(N)ZX unless the bit number is >= 32
- We can fold more than xor using emitTestBit

Also remove a check which isn't relevant anymore + update tests.

Rename select-brcond-of-not.mir to select-brcond-of-binop.mir, since it now
tests more than just G_XOR.

Subject: [PATCH 326/544] [GlobalISel][AArch64] Don't emit cset for G_FCMPs
 feeding into G_BRCONDs

Similar to the FP case in `AArch64TargetLowering::LowerBR_CC`.

Instead of emitting the csets + a tbnz, just emit a compare + bcc
(or two bccs, depending on the condition code)

This improves cases like this: https://godbolt.org/z/v8hebx

This is a 0.1% geomean code size improvement for CTMark at -O3.

Subject: [PATCH 327/544] [flang] Readability improvement in binary->decimal
 conversion

Tweak binary->decimal conversions to avoid an integer multiplication
in a hot loop to improve readability and get a minor (~5%) speed-up.
Use native integer division by constants for more readability, too,
since current build compilers seem to optimize it correctly now.
Delete the now needless temporary work-around facility in
Common/unsigned-const-division.h.

Allows the creation of real SOP1 instructions with
assembler mnemonics that differ from their
pseudo-instruction mnemonics. The default behavior
keeps the mnemonics matching.

Corrects a subtarget label typo in a comment.

Subject: [PATCH 331/544] [memcpyopt] Conservatively handle non-integral
 pointers

If we allow the non-integral pointers to become memset and memcpy, we loose the ability to reason about pointer propagation.  This patch is modeled on changes we've carried downstream for a long time, figured it was worth being equally conservative for other users.  There is room to refine the semantics and handling here if anyone is motivated.

And record numbers are 1-based, not 0-based.
This fixes a bug with rewrites of records that have been
recently read.

Subject: [PATCH 334/544] [XCOFF] Enable -fdata-sections on AIX

Summary:
Some design decision worth noting about:

I've noticed a recent mailing discussing about why string literal is
not affected by -fdata-sections for ELF target:
http://lists.llvm.org/pipermail/llvm-dev/2020-September/145121.html

But on AIX, our linker could not split the mergeable string like other target.
So I think it would make more sense for us to emit separate csect for
every mergeable string in -fdata-sections mode,
as there might not be other ways for linker to do garbage collection
on unused mergeable string.

Subject: [PATCH 335/544] [flang] Fix actions at end of output record

It turns out that unformatted fixed-size output records
do need to be padded out if short, in order to avoid a
spurious EOF crash on a short record at the end of the file.
While here in AdvanceRecord(), move the unformatted
variable-length record header/footer writing code to here
from EndIoStatement().

Subject: [PATCH 339/544] [PowerPC] Put the CR field in low bits of GRC during
 copying CRRC to GRC.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary: How we copying the CRRC to GRC is using a single MFOCRF to copy the contents of CR field n (CR bits 4×n+32:4×n+35) into bits 4×n+32:4×n+35 of register GRC. That’s not correct because we expect the value of destination register equals to source so we have to put the the contents of CR field in the lowest 4 bits. This patch adds a RLWINM after MFOCRF to achieve that.
The problem came up when adding builtins for xvtdivdp, xvtdivsp, xvtsqrtdp, xvtsqrtsp, as posted in D88278. We need to move the outputs (in CR register) to GRC. However outputs of these instructions may not in a fixed CR# register, so we can’t directly add a rotation instruction in the .td patterns, but need to wait until the CR register is determined. Then we confirmed this should be a bug in POST-RA PSEUDO PASS.

Subject: [PATCH 341/544] Have kernel binary scanner load dSYMs as binary+dSYM
 if best thing found

lldb's PlatforDarwinKernel scans the local filesystem (well known
locations, plus user-specified directories) for kernels and kexts
when doing kernel debugging, and loads them automatically.  Sometimes
kernel developers want to debug with *only* a dSYM, in which case they
give lldb the DWARF binary + the dSYM as a binary and symbol file.
This patch adds code to lldb to do this automatically if that's the
best thing lldb can find.

A few other bits of cleanup in PlatformDarwinKernel that I undertook
at the same time:

1. Remove the 'platform.plugin.darwin-kernel.search-locally-for-kexts'
setting.  When I added the local filesystem index at start of kernel
debugging, I thought people might object to the cost of the search
and want a way to disable it.  No one has.

2. Change the behavior of
'plugin.dynamic-loader.darwin-kernel.load-kexts' setting so it does
not disable the local filesystem scan, or use of the local filesystem
binaries.

3. PlatformDarwinKernel::GetSharedModule into GetSharedModuleKext and
GetSharedModuleKernel for easier readability & maintenance.

4. Added accounting of .dSYM.yaa files (an archive format akin to tar)
that I come across during the scan.  I'm not using these for now; it
would be very expensive to expand the archives & see if the UUID matches
what I'm searching for.

Subject: [PATCH 343/544] [gvn] Handle a corner case w/vectors of non-integral
 pointers

If we try to coerce a vector of non-integral pointers to a narrower type (either narrower vector or single pointer), we use inttoptr and violate the semantics of non-integral pointers.  In theory, we can handle many of these cases, we just need to use a different code idiom to convert without going through inttoptr and back.

This shows up as wrong code bugs, and in some cases, crashes due to failed asserts.  Modeled after a change which has lived downstream for a couple years, though completely rewritten to be more idiomatic.

Subject: [PATCH 344/544] [SCEV] Limited support for unsigned preds in
 isImpliedViaOperations

The logic there only considers `SLT/SGT` predicates. We can use the same logic
for proving `ULT/UGT` predicates if all involved values are non-negative.

Adding full-scale support for unsigned might be challenging because of code amount,
so we can consider this in the future.

Subject: [PATCH 345/544] [MLIR] Updates around MemRef Normalization

The documentation for the NormalizeMemRefs pass and the associated MemRefsNormalizable
traits was confusing and not on the website.  This update clarifies the language
around the difference between a MemRef Type, an operation that accesses the value of
MemRef Type, and better documents the limitations of the current implementation.
This patch also includes some basic debugging information for the pass so people
might have a chance of figuring out why it doesn't work on their code.

Subject: [PATCH 346/544] [AArch64] Omit SEH directives for the epilogue if
 none are needed

For these cases, we already omit the prologue directives, if
(!AFI->hasStackFrame() && !windowsRequiresStackProbe && !NumBytes).

When writing the epilogue (after the prolog has been written), if
the function doesn't have the WinCFI flag set (i.e. if no prologue
was generated), assume that no epilogue will be needed either,
and don't emit any epilog start pseudo instruction. After completing
the epilogue, make sure that it actually matched the prologue.

Previously, when epilogue start/end was generated, but no prologue,
the unwind info for such functions actually was huge; 12 bytes xdata
(4 bytes header, 4 bytes for one non-folded epilogue header, 4 bytes
for padded opcodes) and 8 bytes pdata. Because the epilog consisted of
one opcode (end) but the prolog was empty (no .seh_endprologue), the
epilogue couldn't be folded into the prologue, and thus couldn't be
considered for packed form either.

On a 6.5 MB DLL with 110 KB pdata and 166 KB xdata, this gets rid of
38 KB pdata and 62 KB xdata.

Subject: [PATCH 347/544] [SVE][CodeGen] Add new EVT/MVT getFixedSizeInBits()
 functions

When we know that a particular type is always going to be fixed
width we have so far been writing code like this:

  getSizeInBits().getFixedSize()

Since we are doing this in quite a few places now it seems to make
sense to add a new helper function that allows us to replace
these calls with a single getFixedSizeInBits() call.

Subject: [PATCH 348/544] [SVE][CodeGen] Fix implicit TypeSize->uint64_t casts
 in TypePromotion

The TypePromotion pass only operates on scalar types so I've fixed up
all places where we were relying upon the implicit cast from
TypeSize->uint64_t.

Subject: [PATCH 349/544] [WebAssembly] Emulate v128.const efficiently

v128.const was recently implemented in V8, but until it rolls into Chrome
stable, we can't enable it in the WebAssembly backend without breaking origin
trial users. So far we have been lowering build_vectors that would otherwise
have been lowered to v128.const to splats followed by sequences of replace_lane
instructions to initialize each lane individually. That produces large and
inefficient code, so this patch introduces new logic to lower integer vector
constants to a single i64x2.splat where possible, with at most a single
i64x2.replace_lane following it if necessary.

Adapted from a patch authored by @omnisip.

Subject: [PATCH 352/544] [yaml2obj][elf2yaml] - Add a support for the
 `EntSize` field for `SHT_HASH` sections.

Specification  for SHT_HASH table says (https://refspecs.linuxbase.org/elf/gabi4+/ch5.dynamic.html#hash)
that it contains Elf32_Word entries for both 32/64 bit objects.

Currently both GNU linkers and LLD sets the `sh_entsize` field to `4`.

At the same time, `yaml2obj` ignores the `EntSize` field for SHT_HASH sections.
This patch fixes this and also adds a support for obj2yaml: it will not
dump this field when the `sh_entsize` contains the default value (`4`).

Subject: [PATCH 353/544] Fix limit behavior of dynamic alloca

When the allocation size is 0, we shouldn't probe. Within [1,  PAGE_SIZE], we
should probe once etc.

This fixes https://bugs.llvm.org/show_bug.cgi?id=47657

Subject: [PATCH 354/544] [clangd] Remove Tweak::Intent, use CodeAction kind
 directly. NFC

Intent was a nice idea but it ends up being a bit awkward/heavyweight
without adding much.

In particular, it makes it hard to implement `CodeActionParams.only` properly
(there's an inheritance hierarchy for kinds).

From 067add7b5fd22c879bd2bbf5d55f4fb9b63047bf Mon Sep 17 00:00:00 2001
From: Hsiangkai Wang <kai.wang@sifive.com>
Date: Tue, 28 Jul 2020 14:45:28 +0800
Subject: [PATCH 355/544] [RISCV] Support vmsge.vx and vmsgeu.vx pseudo
 instructions in RVV.

Implement vmsge{u}.vx pseudo instruction.

According to RISC-V V specification, there are different scenarios for this
pseudo instruction. I list them below.

unmasked va >= x

  pseudoinstruction: vmsge{u}.vx vd, va, x
  expansion: vmslt{u}.vx vd, va, x; vmnand.mm vd, vd, vd

masked va >= x, vd != v0

  pseudoinstruction: vmsge{u}.vx vd, va, x, v0.t
  expansion: vmslt{u}.vx vd, va, x, v0.t; vmxor.mm vd, vd, v0

masked va >= x, vd == v0

  pseudoinstruction: vmsge{u}.vx vd, va, x, v0.t, vt
  expansion: vmslt{u}.vx vt, va, x;  vmandnot.mm vd, vd, vt

Use pseudo instruction to model vmsge{u}.vx. The pseudo instruction will convert
to different expansion according to the condition.

Subject: [PATCH 356/544] [ARM] Prevent constants from iCmp instruction from
 being hoisted if part of a min(max()) pattern

Marks constants of an ICmp instruction as free if it's only user is a select
instruction that is part of a min(max()) pattern. Ensures that in loops, in
particular when loop unrolling is turned on, SSAT will still be correctly generated.

Subject: [PATCH 358/544] [mlir] Add a subtensor operation

This revision introduces a `subtensor` op, which is the counterpart of `subview` for a tensor operand. This also refactors the relevant pieces to allow reusing the `subview` implementation where appropriate.

This operation will be used to implement tiling for Linalg on tensors.

Subject: [PATCH 363/544] [MLIR][LLVM] Fixed `topologicalSort()` to iterative
 version

Instead of recursive helper method `topologicalSortImpl()`,
sort's implementation is moved to `topologicalSort()` function's
body directly. `llvm::ReversePostOrderTraversal` is used to create
a traversal of blocks in reverse post order.

Subject: [PATCH 366/544] [clangd] Make PopulateSwitch a fix.

It fixes the -Wswitch warning, though we mark it as a fix even if that is off.
This makes it the "recommended" action on an incomplete switch, which seems OK.

Subject: [PATCH 367/544] [AArch64] Add CPU Cortex-R82

This adds support for -mcpu=cortex-r82. Some more information about this
core can be found here:

https://www.arm.com/products/silicon-ip-cpu/cortex-r/cortex-r82

One note about the system register: that is a bit of a refactoring because of
small differences between v8.4-A AArch64 and v8-R AArch64.

This is based on patches from Mark Murray and Mikhail Maltsev.

Subject: [PATCH 376/544] [clangd] Extend the rename API.

several changes:
- return a structure result in rename API;
- prepareRename now returns more information (main-file occurrences);
- remove the duplicated detecting-touch-identifier code in prepareRename (which is implemented in rename API);

Subject: [PATCH 382/544] [Statepoints][ISEL] visitGCRelocate: chain to current
 DAG root.

This is similar to D87251, but for CopyFromRegs nodes.
Even for local statepoint uses we generate CopyToRegs/CopyFromRegs
nodes.  When generating CopyFromRegs in visitGCRelocate, we must chain
to current DAG root, not EntryNode, to ensure proper ordering of copy
w.r.t. statepoint node producing result for it.

Subject: [PATCH 383/544] Fix interaction between stack alignment and
 inline-asm stack clash protection

As reported in https://github.com/rust-lang/rust/issues/70143 alignment is not
taken into account when doing the probing. Fix that by adjusting the first probe
if the stack align is small, or by extending the dynamic probing if the
alignment is large.

Subject: [PATCH 385/544] [mlir] Fix call op conversion in bare-ptr calling
 convention

We hit an llvm_unreachable related to unranked memrefs for call ops
with scalar types. Removing the llvm_unreachable since the conversion
should gracefully bail out in the presence of unranked memrefs. Adding
tests to verify that.

Subject: [PATCH 387/544] [AArch64] Generate dot for v16i8 sum reduction to i32

Convert VECREDUCE_ADD( EXTEND(v16i8_type) ) to VECREDUCE_ADD( DOTv16i8(v16i8_type) ) whenever the result type is i32. This gains in one of the SPECCPU 2017 benchmark.

This partially solves the bug: https://bugs.llvm.org/show_bug.cgi?id=46888
Meta ticket: https://bugs.llvm.org/show_bug.cgi?id=46929

Subject: [PATCH 390/544] [InstCombine] recognizeBSwapOrBitReverseIdiom -
 support for 'partial' bswap patterns (PR47191)

If we're bswap'ing some bytes and zero'ing the remainder we can perform this as a bswap+mask which helps us match 'partial' bswaps as a first step towards folding into a more complex bswap pattern.

Subject: [PATCH 392/544] [CostModel] move default handling after switch; NFC

We will need to add intrinsics to the switch (such as
the ones that are currently in the switch above this
one) that deal with special cases and then break to
the default handling.

Subject: [PATCH 393/544] [MLIR] Better message for FuncOp type mismatch

Previously the actual types were not shown, which makes the message
difficult to grok in the context of long lowering chains.  Also, it
appears that there were no actual tests for this.

Subject: [PATCH 394/544] [mlir] Add Float Attribute, Integer Attribute and
 Bool Attribute subclasses to python bindings.

Based on PyAttribute and PyConcreteAttribute classes, this patch implements the bindings of Float Attribute, Integer Attribute and Bool Attribute subclasses.
This patch also defines the `mlirFloatAttrDoubleGetChecked` C API which is bound with the `FloatAttr.get_typed` python method.

Subject: [PATCH 396/544] [VPlan] Use isa<> instead of directly checking
 VPRecipeID (NFC).

getVPRecipeID is intended to be only used in `classof` helpers. Instead
of checking it directly, use isa<> with the correct recipe type.

 resource directory.

Both of the if-clauses modify the raw_path variable and only one of them
was resetting the variable for the fallback. Avoid future bugs like that
by always resetting the variable.

Subject: [PATCH 407/544] [DAE] MarkLive in MarkValue(MaybeLive) if any use is
 live

While looping through all args or all return values, we may mark a use
of a later iteration as live. Previously when we got to that later value
it would ignore that and continue adding to Uses instead of marking it
live. For example, when looping through arg#0 and arg#1,
MarkValue(arg#0, Live) may cause some use of arg#1 to be live, but
MarkValue(arg#1, MaybeLive) will not notice that and continue adding
into Uses.

Now MarkValue(RA, MaybeLive) will MarkLive(RA) if any use is live.

Fixes PR47444.

Subject: [PATCH 409/544] [libc++] NFCI: Remove _LIBCPP_EXTERN_TEMPLATE2

This seems to have been added a long time ago as a temporary help
for debugging some <regex> issue, but it's really the same as
_LIBCPP_EXTERN_TEMPLATE.

Subject: [PATCH 413/544] [libc++] NFCI: Simplify macro definitions for the
 debug mode

The debug mode always had three possibilities:
- _LIBCPP_DEBUG is undefined => no assertions
- _LIBCPP_DEBUG == 0         => some assertions
- _LIBCPP_DEBUG == 1         => some assertions + iterator checks

This was documented that way, however the code did not make this clear
at all. The discrepancy between _LIBCPP_DEBUG and _LIBCPP_DEBUG_LEVEL
was especially confusing. I reworked how the various macros are defined
without changing anything else to make the code clearer.

Subject: [PATCH 414/544] [libc++] NFCI: Remove the _LIBCPP_DEBUG_MODE helper
 macro

It was used inconsistently and the name was pretty confusing, so we might
as well use `#if _LIBCPP_DEBUG_LEVEL == 2` consistently everywhere.

Subject: [PATCH 415/544] [MLIR][SPIRV] Add initial support for
 OpSpecConstantComposite.

This commit adds support to SPIR-V's composite specialization constants.
These are specialization constants which are composed of other spec
constants (whehter scalar or composite), regular constatns, or undef
values.

This commit adds support for parsing, printing, verification, and
(De)serialization.

A few TODOs are still in order:
- Supporting more types of constituents; currently, only scalar spec constatns are supported.
- Extending `spv._reference_of` to support composite spec constatns.

Subject: [PATCH 417/544] [MemCpyOpt] Avoid double invalidation (NFCI)

The removal of the cpy instruction is left to the caller of
performCallSlotOptzn(), including the invalidation of MD. Both
call-sites already do this.

Also handle incrementation of NumMemCpyInstr consistently at the
call-site. One of the call-site was already doing this, which
ended up incrementing the statistic twice.

This fix was part of D26739.

Subject: [PATCH 419/544] [lldb] Add a "design" section to the documentation.

Create a "Design" section for the LLDB documentation. The goal is to
have design documents that describe how the LLDB internals work.

Currently similar pages  are mixed together under the "Development". The
existing pages describing the architecture, the reproducers, the
structured data plugins, and the SB API could be housed here. I hope
we'd see more pages being added here in the future.

Subject: [PATCH 421/544] Release the shadow memory used by the mmap range at
 munmap

When an application does a lot of pairs of mmap and munmap, if we did
not release shadoe memory used by mmap addresses, this would increase
memory usage.

Subject: [PATCH 423/544] [Hexagon] Move selection of HVX multiply from
 lowering to patterns

Also, change i32*i32 to V6_vmpyieoh + V6_vmpyiewuh_acc, which works
on V60 as well.

This helper method is useful even outside of Gnu toolchains, so move
it to ToolChain so it can be reused in other toolchains such as Fuchsia.

Subject: [PATCH 426/544] [clang-tidy] Implement
 readability-function-cognitive-complexity check

Currently, there is basically just one clang-tidy check to impose
some sanity limits on functions - `clang-tidy-readability-function-size`.
It is nice, allows to limit line count, total number of statements,
number of branches, number of function parameters (not counting
implicit `this`), nesting level.

However, those are simple generic metrics. It is still trivially possible
to write a function, which does not violate any of these metrics,
yet is still rather unreadable.

Thus, some additional, slightly more complicated metric is needed.
There is a well-known [[ https://en.wikipedia.org/wiki/Cyclomatic_complexity | Cyclomatic complexity]], but certainly has its downsides.
And there is a [[ https://www.sonarsource.com/docs/CognitiveComplexity.pdf | COGNITIVE COMPLEXITY by SonarSource ]], which is available for opensource on https://sonarcloud.io/.

This check checks function Cognitive Complexity metric, and flags
the functions with Cognitive Complexity exceeding the configured limit.
The default limit is `25`, same as in 'upstream'.

The metric is implemented as per [[ https://www.sonarsource.com/docs/CognitiveComplexity.pdf | COGNITIVE COMPLEXITY by SonarSource ]] specification version 1.2 (19 April 2017), with two notable exceptions:
   * `preprocessor conditionals` (`#ifdef`, `#if`, `#elif`, `#else`,
     `#endif`) are not accounted for.
      Could be done. Currently, upstream does not account for them either.
   * `each method in a recursion cycle` is not accounted for.
      It can't be fully implemented, because cross-translational-unit
      analysis would be needed, which is not possible in clang-tidy.
      Thus, at least right now, i completely avoided implementing it.

There are some further possible improvements:
* Are GNU statement expressions (`BinaryConditionalOperator`) really free?
  They should probably cause nesting level increase,
  and complexity level increase when they are nested within eachother.
* Microsoft SEH support
* ???

+.. title:: clang-tidy - readability-function-cognitive-complexity
+
+readability-function-cognitive-complexity
+=========================================
+
+Checks function Cognitive Complexity metric.
+
+The metric is implemented as per the `COGNITIVE COMPLEXITY by SonarSource
+<https://www.sonarsource.com/docs/CognitiveComplexity.pdf>`_ specification
+version 1.2 (19 April 2017).
+
+Options
+-------
+
+.. option:: Threshold
+
+   Flag functions with Cognitive Complexity exceeding this number.
+   The default is `25`.
+
+Building blocks
+---------------
+
+There are three basic building blocks of a Cognitive Complexity metric:
+
+Increment
+^^^^^^^^^
+
+The following structures increase the function's Cognitive Complexity metric
+(by `1`):
+
+* Conditional operators:
+
+   - ``if()``
+   - ``else if()``
+   - ``else``
+   - ``cond ? true : false``
+
+* ``switch()``
+* Loops:
+
+   - ``for()``
+   - C++11 range-based ``for()``
+   - ``while()``
+   - ``do while()``
+
+* ``catch ()``
+* ``goto LABEL``, ``goto *(&&LABEL))``,
+* sequences of binary logical operators:
+
+   - ``boolean1 || boolean2``
+   - ``boolean1 && boolean2``
+
+Nesting level
+^^^^^^^^^^^^^
+
+While by itself the nesting level not change the function's Cognitive Complexity
+metric, it is tracked, and is used by the next, third building block.
+The following structures increase the nesting level (by `1`):
+
+* Conditional operators:
+
+   - ``if()``
+   - ``else if()``
+   - ``else``
+   - ``cond ? true : false``
+
+* ``switch()``
+* Loops:
+
+   - ``for()``
+   - C++11 range-based ``for()``
+   - ``while()``
+   - ``do while()``
+
+* ``catch ()``
+* Nested functions:
+
+   - C++11 Lambda
+   - Nested ``class``
+   - Nested ``struct``
+* GNU statement expression
+* Apple Block Declaration
+
+Nesting increment
+^^^^^^^^^^^^^^^^^
+
+This is where the previous basic building block, `Nesting level`_, matters.
+The following structures increase the function's Cognitive Complexity metric by
+the current `Nesting level`_:
+
+* Conditional operators:
+
+   - ``if()``
+   - ``cond ? true : false``
+
+* ``switch()``
+* Loops:
+
+   - ``for()``
+   - C++11 range-based ``for()``
+   - ``while()``
+   - ``do while()``
+
+* ``catch ()``
+
+Examples
+--------
+
+The simplest case. This function has Cognitive Complexity of `0`.
+
+.. code-block:: c++
+
+  void function0() {}
+
+Slightly better example. This function has Cognitive Complexity of `1`.
+
+.. code-block:: c++
+
+  int function1(bool var) {
+    if(var) // +1, nesting level +1
+      return 42;
+    return 0;
+  }
+
+Full example. This function has Cognitive Complexity of `3`.
+
+.. code-block:: c++
+
+  int function3(bool var1, bool var2) {
+    if(var1) { // +1, nesting level +1
+      if(var2)  // +2 (1 + current nesting level of 1), nesting level +1
+        return 42;
+    }
+
+    return 0;
+  }
+
+Limitations
+-----------
+
+The metric is implemented with two notable exceptions:
+   * `preprocessor conditionals` (``#ifdef``, ``#if``, ``#elif``, ``#else``,
+     ``#endif``) are not accounted for.
+   * `each method in a recursion cycle` is not accounted for. It can't be fully
+     implemented, because cross-translational-unit analysis would be needed,
+     which is currently not possible in clang-tidy.

Subject: [PATCH 427/544] [clang] Implement objc_non_runtime_protocol to remove
 protocol metadata

Summary:
Motivated by the new objc_direct attribute, this change adds a new
attribute that remotes metadata from Protocols that the programmer knows
isn't going to be used at runtime. We simply have the frontend skip
generating any protocol metadata entries (e.g. OBJC_CLASS_NAME,
_OBJC_$_PROTOCOL_INSTANCE_METHDOS, _OBJC_PROTOCOL, etc) for a protocol
marked with `__attribute__((objc_non_runtime_protocol))`.

There are a few APIs used to retrieve a protocol at runtime.
`@protocol(SomeProtocol)` will now error out of the requested protocol
is marked with attribute. `objc_getProtocol` will return `NULL` which
is consistent with the behavior of a non-existing protocol.

Subject: [PATCH 430/544] [HIP] Align device binary

To facilitate faster loading of device binaries and share them among processes,
HIP runtime favors their alignment being 4096 bytes. HIP runtime can load
unaligned device binaries, however, aligning them at 4096 bytes results in
faster loading and less shared memory usage.

This patch adds an option -bundle-align to clang-offload-bundler which allows
bundles to be aligned at specified alignment. By default it is 1, which is NFC
compared to existing format.

This patch then aligns embedded fat binary and device binary inside fat binary
at 4096 bytes.

It has been verified this change does not cause significant overall file size increase
for typical HIP applications (less than 1%).

Subject: [PATCH 435/544] [CUDA][HIP] Fix bound arch for offload action for fat
 binary

Currently CUDA/HIP toolchain uses "unknown" as bound arch
for offload action for fat binary. This causes -mcpu or -march
with "unknown" added in HIPToolChain::TranslateArgs or
CUDAToolChain::TranslateArgs.

This causes issue for https://reviews.llvm.org/D88377 since
HIP toolchain needs to check -mcpu in HIPToolChain::TranslateArgs.

The bound arch of offload action for fat binary is not really
used, therefore set it to CudaArch::UNUSED.

Subject: [PATCH 440/544] [CMake] Don't use CMakePushCheckState

When we call cmake_pop_check_state, we undo any changes to REQUIRED
variables performed by HandleLLVMOptions which is undesirable. Rather
use replacement which is what we've used prior to 8d26760a.

Subject: [PATCH 445/544] [X86] Add missing intrinsic test for aesdecwide128kl
 and aesdecwide256kl. Capture all output values in keylocker tests. NFC

The aesdec/enc instructions produce a flag output and one or eight
xmm regsiter outputs. The test were not capturing the xmm outputs.

Also add nounwind to tests to remove .cfi directives

Subject: [PATCH 447/544] [Driver] Move detectLibcxxIncludePath to ToolChain

This helper method is useful even outside of Gnu toolchains, so move
it to ToolChain so it can be reused in other toolchains such as Fuchsia.

Subject: [PATCH 453/544] [Sema] List conversion validate character array.

The function `TryListConversion` didn't properly validate the following
part of the standard:

    Otherwise, if the parameter type is a character array [... ]
    and the initializer list has a single element that is an
    appropriately-typed string literal (8.5.2 [dcl.init.string]), the
    implicit conversion sequence is the identity conversion.

This caused the following call to `f()` to be ambiguous.
    void f(int(&&)[1]);
    void f(unsigned(&&)[1]);

    void g(unsigned i) {
      f({i});
    }

This issue only occurs when the initializer list had one element.

Subject: [PATCH 455/544] [InstCombine] recognizeBSwapOrBitReverseIdiom -
 support for 'partial' bswap patterns (PR47191) (Reapplied)

If we're bswap'ing some bytes and zero'ing the remainder we can perform this as a bswap+mask which helps us match 'partial' bswaps as a first step towards folding into a more complex bswap pattern.

Reapplied with early-out if recognizeBSwapOrBitReverseIdiom collects a source wider than the result type.

Subject: [PATCH 457/544] [flang][NFC] Fix build errors for clang-10

This patch fixes one worning. Since Flang sets `-Werror`, that's
sufficient for a build to fail. As per flang/README.md, Clang-10 is one
of the officially supported compilers.

Subject: [PATCH 460/544] [InstCombine] recognizeBSwapOrBitReverseIdiom - add
 vector support

Add basic vector handling to recognizeBSwapOrBitReverseIdiom/collectBitParts - this works at the element level, all vector element operations must match (splat constants etc.) and there is no cross-element support (insert/extract/shuffle etc.).

Subject: [PATCH 461/544] [ARM] Fix pointer offset when splitting stores from
 VMOVDRR

We were not accounting for the pointer offset when splitting a store from
a VMOVDRR node, which could lead to incorrect aliasing info. In this
case it is the fneg via integer arithmetic that gives us a store->load
pair that we started getting wrong.

Subject: [PATCH 462/544] Add indented raw_ostream class

Class simplifies keeping track of the indentation while emitting. For every new line the current indentation is simply prefixed (if not at start of line, then it just emits as normal). Add a simple Region helper that makes it easy to have the C++ scope match the emitted scope.

Use this in op doc generator and rewrite generator.

Subject: [PATCH 465/544] [Analysis] resolveAllCalls - fix use after std::move
 warning. NFCI.

We can't use Use.Calls after its std::move()'d to TmpCalls as it will be in an undefined state. Instead, swap with the known empty map in TmpCalls so we can then safely emplace_back into the now empty Use.Calls.

Fixes clang static analyzer warning.

Subject: [PATCH 467/544] [asan] Stop instrumenting user-defined ELF sections

Do not instrument user-defined ELF sections (whose names resemble valid
C identifiers).  They may have special use semantics and modifying them
may break programs.  This is e.g. the case with NetBSD __link_set API
that expects these sections to store consecutive array elements.

Subject: [PATCH 468/544] [lldb] [Process/NetBSD] Fix reading FIP/FDP registers

Fix reading FIP/FDP registers to correctly return segment and offset
parts.  On amd64, this roughly matches the Linux behavior of splitting
the 64-bit FIP/FDP into two halves, and putting the higher 32 bits
into f*seg and lower into f*off.  Well, actually we use only 16 bits
of higher half but the CPUs do not seem to handle more than that anyway.

Subject: [PATCH 469/544] [lldb] [Process/NetBSD] Fix crash on unsupported i386
 regs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Multiple fixes related to bugs discovered while debugging a crash
when reading all registers on i386.

The underlying problem was that GetSetForNativeRegNum() did not account
for MPX registers on i386, and since it only compared against upper
bounds of each known register set, the MPX registers were classified
into the wrong set and therefore considered supported.  However, they
were not expected in RegNumX86ToX86_64() and caused the assertion
to fail.

This includes:

- adding (unused) i386 → x86_64 translations for MPX registers
- fixing GetSetForNativeRegNum() to check both lower and upper bound
  for register sets, to avoid wrongly classifying unhandled register
  sets
- adding missing range check for MPX registers on i386
- renaming k_last_mpxr to k_last_mpxr_i386 for consistency
- replacing return-assertions with llvm_unreachable() and adding more
  checks for unexpected parameters

Subject: [PATCH 470/544] [lldb] [test/Register] Add read/write tests for x87
 regs

Add a partial read/write tests for x87 FPU registers.  This includes
reading and writing ST registers, control registers and floating-point
exception data registers (fop, fip, fdp).

The tests assume the current (roughly incorrect) behavior of reporting
the 'abridged' 8-bit ftag state as 16-bit ftag.  They also assume Linux
plugin behavior of reporting fip/fdp split into halves as (fiseg, fioff)
and (foseg, fooff).

Subject: [PATCH 473/544] [AArch64] Match the windows canonical callee saved
 register order

On windows, the callee saved registers in a canonical prologue are
ordered starting from a lower register number at a lower stack
address (with the possible gap for aligning the stack at the top);
this is the opposite order that llvm normally produces.

To achieve this, reverse the order of the registers in the
assignCalleeSavedSpillSlots callback, to get the stack objects
laid out by PrologEpilogInserter in the right order, and adjust
computeCalleeSaveRegisterPairs to lay them out from the bottom up.

This allows generated prologs more often to match the format that
allows the unwind info to be written as packed info.

Differential Revision: https://reviews.llvm.org/D88677

Subject: [PATCH 474/544] [AArch64] Allow pairing lr with other GPRs for WinCFI

This saves one instruction per prologue/epilogue for any function with
an odd number of callee-saved GPRs, but more importantly, allows such
functions to match the packed unwind format.

Subject: [PATCH 475/544] [AArch64] Prefer prologues with sp adjustments merged
 into stp/ldp for WinCFI, if optimizing for size

This makes the prologue match the windows canonical layout, for
cases without a frame pointer.

This can potentially be a slower (a longer dependency chain of the
sp register, and potentially one arithmetic operation more on some
cores), but gives notable size improvements.

The previous two commits shrinks a 166 KB xdata section by 49 KB,
and if the change from this commit is enabled, it shrinks the xdata
section by another 25 KB.

In total, since the start of the recent arm64 unwind info cleanups
and optimizations (since before commit 37ef743cbf3), the xdata+pdata
sections of the same test DLL has shrunk from 407 KB in total
originally, to 163 KB now.

Subject: [PATCH 477/544] [NFC][PhaseOrdering] Add a test showing new inttoptr
 casts after SROA due to InstCombine (PR47592)

We could either try to make SROA more picky to the new type
and/or prevent InstCombine from creating the original problem (converting load-stores to operate on ints),
and/or make InstCombine recover the situation by cleaning up all that cruft.

Subject: [PATCH 479/544] [VPlan] Properly update users when updating operands.

When updating operands of a VPUser, we also have to adjust the list of
users for the new and old VPValues. This is required once we start
transitioning recipes to become VPValues.

Subject: [PATCH 481/544] [MC] Assert that MCRegUnitIterator operates over
 MCRegisters

The signature of the ctor expects a MCRegister, but currently any
unsigned value can be converted to a MCRegister.

This patch checks that indeed the provided value is a physical register
only. We want to eventually stop implicitly converting unsigned or
Register to MCRegister (which is incorrect). The next step after this
patch is changing uses of MCRegUnitIterator to explicitly cast Register
or unsigned values to MCRegister. To that end, this patch also
introduces 2 APIs that make that conversion checked and explicit.

Subject: [PATCH 483/544] Add indented raw_ostream class

Class simplifies keeping track of the indentation while emitting. For every new line the current indentation is simply prefixed (if not at start of line, then it just emits as normal). Add a simple Region helper that makes it easy to have the C++ scope match the emitted scope.

Use this in op doc generator and rewrite generator.

This reverts revert commit be185b6a7355fdfeb1c31df2e1272366fe58b01f addresses shared lib failure by fixing up cmake files.

Subject: [PATCH 484/544] [X86] Add X86ISD opcodes for the Key Locker AESENC*KL
 and AESDEC*KL instructions

Instead of emitting MachineSDNodes during lowering, emit X86ISD
opcodes. These opcodes will either be selected by tablegen
patterns or custom selection code.

Emitting MachineSDNodes during lowering is uncommon so this makes
things more consistent. It also allows selectAddr to be called to
perform address matching during instruction selection.

I had trouble getting tablegen to accept XMM0-XMM7 as results in
an isel pattern for the WIDE instructions so I had to use custom
instruction selection.

Subject: [PATCH 485/544] [RFC] Factor out repetitive cmake patterns for
 llvm-style projects

New projects (particularly out of tree) have a tendency to hijack the existing
llvm configuration options and build targets (add_llvm_library,
add_llvm_tool).  This can lead to some confusion.

1) When querying a configuration variable, do we care about how LLVM was
configured, or how these options were configured for the out of tree project?
2) LLVM has lots of defaults, which are easy to miss
(e.g. LLVM_BUILD_TOOLS=ON).  These options all need to be duplicated in the
CMakeLists.txt for the project.

In addition, with LLVM Incubators coming online, we need better ways for these
incubators to do things the "LLVM way" without alot of futzing.  Ideally, this
would happen in a way that eases importing into the LLVM monorepo when
projects mature.

This patch creates some generic infrastructure in llvm/cmake/modules and
refactors MLIR to use this infrastructure.  This should expand to include
add_xxx_library, which is by far the most complicated bit of building a
project correctly, since it has to deal with lots of shared library
configuration bits.  (MLIR currently hijacks the LLVM infrastructure for
building libMLIR.so, so this needs to get refactored anyway.)

We should avoid emitting MachineSDNodes from lowering.

We can use the the implicit def handling in InstrEmitter to avoid
manually copying from each xmm result register. We only need to
manually emit the copies for the implicit uses.

Subject: [PATCH 492/544] [OldPM] Pass manager: run SROA after (simple) loop
 unrolling

I have stumbled into this pretty accidentally, when rewriting
some spaghetti-like code into something more structured,
which involved using some `std::array<>`s. And to my surprise,
the `alloca`s remained, causing about `+160%` perf regression.

https://llvm-compile-time-tracker.com/compare.php?from=bb6f4d32aac3eecb51909f4facc625219307ee68&to=d563e66f40f9d4d145cb2050e41cb961e2b37785&stat=instructions
suggests that this has geomean compile-time cost of `+0.08%`.

Note that D68593 / cecc0d27ad58c0aed8ef9ed99bbf691e137a0f26
already did this chage for NewPM, but left OldPM in a pessimized state.

This fixes [[ https://bugs.llvm.org/show_bug.cgi?id=40011 | PR40011 ]], [[ https://bugs.llvm.org/show_bug.cgi?id=42794 | PR42794 ]] and probably some other reports.

Subject: [PATCH 494/544] [CodeGen] Improve likelihood branch weights

Bruno De Fraine discovered some issues with D85091. The branch weights
generated for `logical not` and `ternary conditional` were wrong. The
`logical and` and `logical or` differed from the code generated of
`__builtin_predict`.

Adjusted the generated code for the likelihood to match
`__builtin_predict`. The patch is based on Bruno's suggestions.

Subject: [PATCH 496/544] [X86][SSE] isTargetShuffleEquivalent - ensure shuffle
 inputs are the correct size.

Preliminary patch for the next stage of PR45974 - we don't want to be creating 'padded' vectors on-the-fly at all in combineX86ShufflesRecursively, and only pad the source inputs if we have a definite match inside combineX86ShuffleChain.

This means that the inputs to combineX86ShuffleChain might soon be smaller than the final root value type, so we should ensure that isTargetShuffleEquivalent only matches with the inputs if they are the correct size.

Subject: [PATCH 497/544] [MemCpyOpt] Add additional call slot tests (NFC)

The case of a destination read between call and memcpy was not
covered anywhere (but is handled correctly).

However, a potentially throwing call between the call and the
memcpy appears to be miscompiled.

Subject: [PATCH 498/544] [SDAG] fold x * 0.0 at node creation time

In the motivating case from https://llvm.org/PR47517
we create a node that does not get constant folded
before getNegatedExpression is attempted from some
other node, and we crash.

By moving the fold into SelectionDAG::simplifyFPBinop(),
we get the constant fold sooner and avoid the problem.

Subject: [PATCH 499/544] [PowerPC] Add builtins for xvtdiv(dp|sp) and
 xvtsqrt(dp|sp).

Summary: This patch implements the builtins for xvtdivdp, xvtdivsp, xvtsqrtdp, xvtsqrtsp.
The instructions correspond to the following builtins:
int vec_test_swdiv(vector double v1, vector double v2);
int vec_test_swdivs(vector float v1, vector float v2);
int vec_test_swsqrt(vector double v1);
int vec_test_swsqrts(vector float v1);
This patch depends on D88274, which fixes the bug in copying from CRRC to GPRC/G8RC.

 replaceAllUsesWith.

Make sure we do not iterate using an invalid iterator.

Another small fix/step towards traversing the def-use chains in VPlan.

Subject: [PATCH 502/544] [VPlan] Add VPRecipeBase::toVPUser helper (NFC).

This adds a helper to convert a VPRecipeBase pointer to a VPUser, for
recipes that inherit from VPUser. Once VPRecipeBase directly inherits
from VPUser this helper can be removed.

Subject: [PATCH 505/544] [X86] Synchronize the encodekey builtins with gcc.
 Don't assume void* is 16 byte aligned.

We were taking multiple pointer arguments in the builtin.
gcc accepts a single void*.

The cast from void* to _m128i* caused the IR generation to assume
the pointer was aligned.

Instead make the builtin take a single void*, emit i8* GEPs to
adjust then cast to <2 x i64>* and perform a store with align of 1.

Subject: [PATCH 510/544] [MemCpyOpt] Don't use array allocas in tests (NFC)

being intentionally penalized (https://reviews.llvm.org/D41398),
so avoid using them in tests.

+; While we can't treat inttoptr/ptrtoint casts as fully transparent,
+; instead of modelling them as fully opaque (unknown), we can at least model
+; their source values are opaque (unknown). Which, given e.g.:
+;   %x = ???
+;   %y = inttoptr %x
+;   %z = inttoptr %x
+; at least allows us to tell that %y and %z are identical.
+; Note that we must stop at that, we can not further analyze %x itself.

Subject: [PATCH 516/544] Revert "[RFC] Factor out repetitive cmake patterns
 for llvm-style projects"

This reverts commit e9b87f43bde8b5f0d8a79c5884fdce639b12e0ca.

There are issues with macros generating macros without an obvious simple fix
so I'm going to revert this and try something different.

Subject: [PATCH 518/544] [X86] Correct the implicit defs/uses for the MWAITX
 pseudo instructions.

MWAITX doesn't touch EFLAGS so no pseudos should def EFLAGS.

The SAVE_EBX/RBX pseudos only needs to def the EBX register that
the expansion overwrites. The EAX and ECX registers are only read.

The pseudo emitted during isel that is used by the custom inserter
shouldn't have any implicit defs or uses since everything is in
vregs.

Subject: [PATCH 519/544] [DomTree] findNearestCommonDominator: assert the
 nodes are in tree

i.e. they cannot be unreachable from the entry (which usually indicate usage errors).
This change allows the removal of some nullptr checks.

Subject: [PATCH 522/544] [NewPM] collapsing nested pass mangers of the same
 type

This is one of the reason for extra invalidations in D84959. In
practice, I don't think we have use cases needing this. This simplifies
the pipeline a bit and prune corner cases when considering
invalidations.

Subject: [PATCH 524/544] [X86] Remove MWAITX_SAVE_EBX pseudo instruction.
 Always save/restore the full %rbx register even in gnux32.

ebx/rbx only needs to be saved when 64-bit registers are supported
anyway. It should be fine to save/restore the whole rbx register
even in gnux32 where the base is technically just ebx.

This matches what we do for cmpxchg16b where rbx is saved/restored
regardless of gnux32.

Subject: [PATCH 526/544] [HIP] Add option --gpu-instrument-lib=

Add an option --gpu-instrument-lib= to allow users to specify
an instrument device library. This is for supporting -finstrument
in device code for debugging/profiling tools.

Subject: [PATCH 529/544] [HIP] Fix default output file for -E

By convention the default output file for -E is "-" (stdout).
This is expected by tools like ccache, which uses output
of -E to determine if a file and its dependence has changed.

Currently clang does not use stdout as default output file for -E
for HIP, which causes ccache not working.

This patch fixes that.

Subject: [PATCH 532/544] Handle @llvm.memset.* with non-constant arguments
 (#696)

* Handle @llvm.memset.* with non-constant arguments

There is no SPIR-V counterpart for @llvm.memset.* intrinsic. Cases with constant
value and length arguments are emulated via "storing" a constant array to the
destination.

For other cases we wrap the intrinsic in @spirv.llvm_memset_* function and
expand the intrinsic to a loop via expandMemSetAsLoop() from
llvm/Transforms/Utils/LowerMemIntrinsics.h.

During reverse translation from SPIR-V to LLVM IR we can detect
@spirv.llvm_memset_* and replace it with @llvm.memset.

Subject: [PATCH 536/544] Rename OCL20ToSPIRV pass

Renamed the pass to OCLToSPIRV: the problem with the old name is that it
doesn't represent actual pass content: it handles not only OpenCL C 2.0
built-in functions, but also OpenCL C 1.2 built-in functions, acting
like an adapter between OpenCL C representation and SPIR-V friendly IR
representation. Also updated some comments to reflect that.

Subject: [PATCH 537/544] Remove OCL21ToSPIRV pass

Since
KhronosGroup/SPIRV-LLVM-Translator@6ceea975375b44fe0238fb30f6dffc50a9c33fb5
this pass only handles input files coming out OpenCL C++ 2.1, which
technically doesn't exists and therefore this should be a dead code.

Additionally: most of the pass functionality (except sub-group barrier
handling) is untested and duplicated in OCLToSPIRV pass.

Subject: [PATCH 543/544] Fix emission of SPIR-V friendly IR for OpenCL EIS
 (#746)

Added possibility to emit SPIR-V friendly IR instead of OpenCL-C-like
mangled function names for instructions from OpenCL extended instruction
set.
