Thomas,
Any plans to fix
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64635 soon? On x86_64
darwin, the OpenACC merge resulted a huge number of failures in the
libgomp test suite…
=== libgomp Summary ===
# of expected passes 10628
# of unexpected failures 724
# of unsupported tests 562
which are resolved with a fix similar to
https://gcc.gnu.org/bugzilla/attachment.cgi?id=34480.
