With commit r14-6082-gf4dd9416843308d4ae519983415fe62212662536 "libsupc++: try
cxa_thread_atexit_impl at runtime", there's one regression in nvptx target
testing (only visible on top of my WIP C++ enablement changes):
[-PASS:-]{+FAIL:+} g++.dg/tls/thread_local6.C -std=c++14 (test for excess
errors)
[-PASS:-]{+UNRESOLVED:+} g++.dg/tls/thread_local6.C -std=c++14 [-execution
test-]{+compilation failed to produce executable+}
[-PASS:-]{+FAIL:+} g++.dg/tls/thread_local6.C -std=c++17 (test for excess
errors)
[-PASS:-]{+UNRESOLVED:+} g++.dg/tls/thread_local6.C -std=c++17 [-execution
test-]{+compilation failed to produce executable+}
[-PASS:-]{+FAIL:+} g++.dg/tls/thread_local6.C -std=c++20 (test for excess
errors)
[-PASS:-]{+UNRESOLVED:+} g++.dg/tls/thread_local6.C -std=c++20 [-execution
test-]{+compilation failed to produce executable+}
UNSUPPORTED: g++.dg/tls/thread_local6.C -std=c++98
unresolved symbol __cxa_thread_atexit_impl
collect2: error: ld returned 1 exit status
Very likely, this isn't an issue with that commit, but rather due to GCC/nvptx'
deficient implementation of weak symbols.
