--- Comment #1 from Rainer Orth <ro at gcc dot gnu.org> ---
To add some background: I've been experiencing ca. 250 test failures in the
LLVM
testsuite when building for sparcv9-sun-solaris2.11.
As a workaround, I've posted
[cmake] Don't build with -O3 -fPIC on Solaris/sparcv9
https://reviews.llvm.org/D85630
based on the observation that the SEGVs vanish if LLVM is compiled with -O
-fPIC
only instead of the default -O3 -fPIC.
I've been using the following slightly reduced example (attached):
* tqt.cpp is reduced from LLVM's llvm/unittests/Support/TaskQueueTest.cpp.
* ThreadPool.cpp is LLVM 10.0.0 llvm/lib/Support/ThreadPool.cpp.
They can be compiled and linked with the included tqt.sh; however that relies
on
LLVM 10 bundled with Solaris 11.4 for LLVM headers, libLLVMSupport and
libLLVMDemangle.
I haven't tried to produce a further reduced example yet.
