<div dir="auto">Hi, thanks for quick reply. I have tried lifting the restriction (setting LIBOMP_HAVE_TSAN_SUPPORT to TRUE) in both branches but unfortunately I got 1 or 2 errors when compiling from`llvm-project` or from `PRUNERS/openmp`. For the completeness they are at the bottom of the message. My Clang version is 8.0.0. Is there some plan to support the TSAN on macOS soon? Otherwise I will try to manually compile archer and hope it will work (already tried to install through spack but it failed - was hanging over an hour on installation of perl).

<br />
the logic to detect whether the TSan annotations might be supported on<br />
your platform is quite simple in the OpenMP runtime. We only tested this<br />
on x86_64 Linux, so this is the only platform that is flagged supported in<br />
<br />
runtime/cmake/config-ix.cmake:280<br />
<br />
You might just remove/modify that lines. But I remember that there are<br />
some issues with the weak implementation workflow in the TSan annotations.<br />
<br />
<br />
I would suggest you to try this branch instead:<br />
<br />
https://github.com/PRUNERS/openmp/tree/archer_80<br />
<br />
I will push this to upstream soon, but did not find the time to update<br />
my patch in phabricator yet.<br />
<br />
Best<br />
Joachim<br />

As the default clang is outputting false positives when running openmp<br />
program I wanted to compile openmp with TSAN (thread sanitizer) support.<br />
Unfortunately when I tried to compile openmp I got an error that says:<br />
"TSAN functionality requested but not available". What does it mean not<br />
available? Should I install something extra (what if it is the case)?<br />
(maybe helps: currently when compiling`clang -fsanitize=thread -g<br />
-O1 tiny_race.c` I get no error). Running on macOS 10.14.4 (18E226).<br />
Here is the output of `cmake -DCMAKE_C_COMPILER=clang<br />
-DCMAKE_CXX_COMPILER=clang++ -DLIBOMP_TSAN_SUPPORT=1 ../openmp` (the<br />
openmp repository is cloned from https://github.com/llvm/llvm-project):<br />
<br />
Thank you for any hints how to fix this error.<br />
Regards,<br />
Jan<br />
