[Flang] Unlimited polymorphic ARRAY= argument is not supported by intrinsic EOSHIFT #115923
Description
Consider the following code:
module m
type Base
integer i
end type
type, extends(Base) :: Child
integer j
end type
end module
program transfer003
use m
class(Base), pointer :: c1(:,:,:)
class(*), pointer :: b1(:)
allocate(c1(2,2,2), SOURCE=reshape((/(Child(i,i-1),i=101,108)/), &
(/2,2,2/)))
allocate(b1(12), SOURCE=(/(Base(i),i=1,12)/))
select type(name1=>eoshift(transfer(c1, b1), -4, Base(-8)))
type is (Base)
print *, name1
class default
error stop 1
end select
end
Flang issues an error as
t1.f:20:32: error: Actual argument for 'array=' has bad type 'CLASS(*)'
select type(name1=>eoshift(transfer(c1, b1), -4, Base(-8)))
^^^^^^^^^^^^^^^^
The standard doesn't seem disallow unlimited polymorphic in this case.
XLF compiles and runs successfully.
gfortran issues a TODO message
