Thanks for looking at this, but your patch is essentially papering over the
problem.
It took me a while to figure out, but the clue was that things like
'decltype(f()).m' worked, but 'decltype(f()){0}' did not. The CONSTRUCTOR node
is the exception to the rule that required an expression node

In the PR, Joseph says that in C char8_t is not a distinct type. So
we should behave as if it can alias anything, like ordinary char.
In C, unsigned_char_type_node == char8_type_node, so with this patch
we return 0 instead of -
Tested x86_64-pc-linux-gnu, applying to trunk.

This patch adds C++ support for OpenMP's 'omp allocate' for
stack/automatic arrays.
Comments and suggestions? — I bet there are given my little knowledge
about the C++ FE...

I studied a little bit more on the following question you raised during the
review process:
For the following small testing case:
1 struct annotated {
2 int foo;
3 char array[] __attribute__((counted_by (foo)));
Hi,
For the following test-case:
typedef float __attribute__((__vector_size__ (16))) F;
F foo (F a, F b)
{
F v = (F) { 9 };
return __builtin_shufflevector (v, v, 1, 0, 1, 2);
}
Compiling with -O2 results in following ICE:

This patch removes stray NON_DEPENDENT_EXPR checks following the removal
of this tree code from the C++ FE. (Since this restores the build I
supppose it means the Rust FE never creates NON_DEPENDENT_EXPR trees in

This patch broke bootstrap on AIX because ASM_GENERATE_INTERNAL_LABEL can
embed target-specific functions. Fixed by including tm_p.h.
Thanks, David
