When compiling with -fopenmp-simd, there is an ICE if a function has a
return type of a typedef of void. (e.g., "typedef void T; T foo()").
Corrected by changing:
if (orig_rettype == void_type_node)
to :
if (VOID_TYPE_P (orig_rettype))
gcc/ChangeLog:
PR middle-end/111856
* omp-simd-clone.cc (simd_clone_adjust_return_type): Use
VOID_TYPE_P instead of comparison with void_type_node.
(simd_clone_adjust): Likewise.
gcc/testsuite/ChangeLog:
PR middle-end/111856
* c-c++-common/gomp/pr111856.c: New test.
