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?
Looking at [1], it seems that only the bare-metal configurations are affected. And looking at [2], the tests are failing with === undefined reference to `__aeabi_read_tp' === .
Given that we are configuring GCC for arm-none-eabi with "--enable-threads=no", the failure is not a surprise.
[1] https://linaro.atlassian.net/browse/GNU-1112 [2] https://ci.linaro.org/job/tcwg_gnu_embed_check_gcc--master-arm_eabi-build/57...
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 }
Yes, this should skip the testcase for targets without thread/TLS support.
Please let me know if the issue is something else and I can take another look.
Thanks!
