Extended Description

llc fails an assertion in the ScheduleDAG at line number 885. The following assert is not satisfied.
Assertion '0 && This target-independent node should have been selected'

I am using llvm-2.3 with svn revision number 53702
and llvm-gcc with svn revision number 53705.
Host machine is x86-64 base and run suse linux.
llvm is compiled using gcc-4.2.0

I have attached the reduced bitcode generated by bugpoint, for the spec 2006 benchmark 470.lbm with a custom transformation run through opt. The bitcode has been verified after the custom transformation using -verify-each argument to opt.

This is still present in svn head.

This now works for me:

$ llc bugpoint-reduced-simplified.bc

I think that this was fixed on mainline recently.
