Thanks for the notification! I took a look and the error seems to be
something specific to the TLS implementation for ARM requiring
additional flags to link correctly, maybe?
I'm unable to test locally (I don't have access to an ARM machine) but
from looking at other testsuite examples which make use of thread
locals, adding the following two lines to the testcases may resolve the
failures:
// { dg-add-options tls }
// { dg-require-effective-target tls_runtime }
Please let me know if the issue is something else and I can take
another look.
Yours,
Nathaniel.
