--- Comment #13 from Christoph <foss at grueninger dot de> ---
I tried to help with reducing the test case, but could not achieve something
substantial.
Then I went back to our test cases and tried to pick the simples one I could
find. I removed as much code from main() as I could. The resulting test case
looks only slightly smaller (7 MiB instead of 8 MiB) but it should boil down to
a smaller test case. Not sure which route is going to lead to faster results.

Reduced:

--- Comment #16 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I remember dealing with this elsewhere (in declare variant support).
I had to do:
- variant = cp_get_callee_fndecl_nofold (variant);
+ variant = cp_get_callee (variant);
+ if (variant)
+ {
+ if (TREE_CODE (variant) == FUNCTION_DECL)
+ ;
+ else if (TREE_TYPE (variant) && INDIRECT_TYPE_P (TREE_TYPE (variant)))
+ variant = cp_get_fndecl_from_callee (variant, false);
+ else
+ variant = NULL_TREE;
+ }
because cp_get_callee_fndecl_nofold would ICE (I think exactly like this one))
when feeded during processing_template_decl with something it doesn't expect to
see.

Ah, omp_declare_variant_finalize_one. I think I'll do something similar, but
not the same: if we see a CALL_EXPR whose CALL_EXPR_FN is a BASELINK, we know
it's not the std::is_constant_evaluated call we're looking for. Thanks.

Actually it might be better to make it out to a function and use that in both
places, otherwise I'm either duplicating code or it's just too ugly.

c++: ICE with -Wall and constexpr if [PR94937]
An ICE arises here because we call cp_get_callee_fndecl_nofold in a
template, and we've got a CALL_EXPR whose CALL_EXPR_FN is a BASELINK.
This tickles the INDIRECT_TYPE_P assert in cp_get_fndecl_from_callee.
Fixed by turning the assert into a condition and returning NULL_TREE
in that case.
PR c++/94937
* cvt.c (cp_get_fndecl_from_callee): Return NULL_TREE if the
function
type is not INDIRECT_TYPE_P.
* decl.c (omp_declare_variant_finalize_one): Call
cp_get_callee_fndecl_nofold instead of looking for the function
decl
manually.
* g++.dg/cpp1z/constexpr-if34.C: New test.
* g++.dg/cpp2a/is-constant-evaluated10.C: New test.
