Please let us know if you have a fix.
I should have a fix: the attached "Adjust 'libgomp.c++/target-cdtor-{1,2}.C' for 'targetm.cxx.use_aeabi_atexit' [PR119853, PR119854]" ought to address this. I've "mock-tested" this locally; is there a way for me to run this through the Linaro "pre-commit" CI?

Hi Thomas,
Is it expected that I'm not able to log into the Jira instance,
Yes, you can't log into Jira, but the regression cards are publicly accessible without a login.
and that most of the links in there are either:
| Secure Connection Failed | | An error occurred during a connection to git-us.linaro.org. Cannot communicate securely with peer: no common encryption algorithm(s).
..., or:
| Oops! | | Not Found | | This page may not exist, or you may not have permission to see it.
This is a known problem that we are fixing. We are migrating away from git*.linaro.org http://linaro.org/ servers to gitlab.com http://gitlab.com/, but we haven't updated the links yet. Sorry!
Please let us know if you have a fix.
I should have a fix: the attached "Adjust 'libgomp.c++/target-cdtor-{1,2}.C' for 'targetm.cxx.use_aeabi_atexit' [PR119853, PR119854]" ought to address this. I've "mock-tested" this locally; is there a way for me to run this through the Linaro "pre-commit" CI?
Hi Christophe,
Would you please give Thomas's patch a go?
Thanks!

Hi Christophe,

Actually, no need: I've now found that on https://patchwork.sourceware.org/project/gcc/patch/875xfp7m4b.fsf@euler.schwinge.ddns.net/, we (by now) have:
| Context Check Description | [...] | linaro-tcwg-bot/tcwg_gcc_check--master-arm success Test passed
..., and the linked https://ci.linaro.org/job/tcwg_gcc_check--master-arm-precommit/12469/artifact/artifacts/artifacts.precommit/notify/mail-body.txt states:
| Produces 10 fixes: | | | | fixes.sum: | | Running libgomp:libgomp.c++/c++.exp ... | | FAIL: libgomp.c++/target-cdtor-1.C scan-tree-dump-times optimized "gimple_call <__cxa_atexit, " 4 | | FAIL: libgomp.c++/target-cdtor-1.C scan-tree-dump-times optimized "gimple_call <__cxa_atexit, NULL, _ZN1SD1Ev, \&sHD1, \&__dso_handle>" 1 | | FAIL: libgomp.c++/target-cdtor-1.C scan-tree-dump-times optimized "gimple_call <__cxa_atexit, NULL, _ZN1SD1Ev, \&sH2, \&__dso_handle>" 1 | | FAIL: libgomp.c++/target-cdtor-1.C scan-tree-dump-times optimized "gimple_call <__cxa_atexit, NULL, _ZN1SD1Ev, \&sH1, \&__dso_handle>" 1 | | ... and 6 more
That's exactly what I needed to know. Great service! I've therefore pushed to trunk branch commit 04b42c4245d85f77aa54ec002ebd7bbe6fde5f11 "Adjust 'libgomp.c++/target-cdtor-{1,2}.C' for 'targetm.cxx.use_aeabi_atexit' [PR119853, PR119854]".
