[LSAN][HWASAN] Run LSAN tests with HWASAN enabled

[kstoimenov]

Summary

A lot of tests are disabled by using UNSUPPORTED. The plan is to remove UNSUPPORTED for tests that are fixed.

You can have multiple // UNSUPPORTED
Comment would be nice

[kstoimenov]

Made all unsupported.

[kstoimenov]

Only one unsupported.

why if (arch STREQUAL "x86_64")?
add FIXME if it's temporarily

[kstoimenov]

Added fixme.

Done.

Hi, is there any plan to support hwasan leak check on Android? :)

[hans]

I think this broke Mac: https://green.lab.llvm.org/green/job/clang-stage1-RA/32739/

For example:

LeakSanitizer-HWAddressSanitizer-x86_64.TestCases/Darwin.dispatch.mm (from LeakSanitizer-HWAddressSanitizer-x86_64)

[kstoimenov]

Added some previous fixes.

[kstoimenov]

Removed Apple as it is not supported by HWASAN.

Looks like -fsanitize=hwaddress is not supported on Mac. I re-landed this with Mac disabled. Will keep an eye on your builds.

I am working on generic support, focusing on x86 for now. Theoretically it should work on ARM, but I haven't tried that. I am also not sure is there anything specific which needs to be done to make it work on Android on top of making it work on ARM. You can try flipping the cf.detect_leaks flag in compiler-rt/lib/hwasan/hwasan.cpp to see if it works :-)
