[release_34] [compiler_rt] Unsupported tests on PPC64

Hi,

When running clang test on PPC64 I get:

/usr/lib64/gcc/powerpc64-suse-linux/4.8/…/…/…/…/powerpc64-suse-linux/bin/ld: cannot find /home/abuild/rpmbuild/BUILD/llvm/stage2/bin/…/lib64/clang/3.4/lib/linux/libclang_rt.ubsan-powerpc64.a: No such file or directory

So I think ubsan is unsupported on PPC64 and tests should be disabled. Also same for more sanitizers:

[while compiling compiler-rt/lib/tsan/lit_tests/vptr_benign_race.c]
clang-3.4: error: unsupported option ‘-fsanitize=thread’ for target ‘powerpc64-unknown-linux-gnu’

[while compiling compiler-rt/lib/msan/lit_tests/Output/ptrace.cc]
clang-3.4: error: unsupported option ‘-fsanitize=memory’ for target ‘powerpc64-unknown-linux-gnu’

[while testing compiler-rt/lib/asan/lit_tests/TestCases/deep_call_stack.cc]

==29868==AddressSanitizer: detect_leaks is not supported on this platform.

[while compiling compiler-rt/lib/dfsan/lit_tests/Output/custom.c]
clang-3.4: error: unsupported option ‘-fsanitize=dataflow’ for target ‘powerpc64-unknown-linux-gnu’

So, shall I completely disable compiler-rt for PPC64/Linux?

Thanks!

Hi,

When running clang test on PPC64 I get:

/usr/lib64/gcc/powerpc64-suse-linux/4.8/../../../../powerpc64-suse-linux/bin/ld:
cannot find

Probably so, but I'll let ubsan folks speak.

[while compiling compiler-rt/lib/tsan/lit_tests/vptr_benign_race.c]
clang-3.4: error: unsupported option '-fsanitize=thread' for target
'powerpc64-unknown-linux-gnu'

tsan is not supported on anything other than Linux x86_64

[while compiling compiler-rt/lib/msan/lit_tests/Output/ptrace.cc]
clang-3.4: error: unsupported option '-fsanitize=memory' for target
'powerpc64-unknown-linux-gnu'

same for msan

[while testing compiler-rt/lib/asan/lit_tests/TestCases/deep_call_stack.cc]

==29868==AddressSanitizer: detect_leaks is not supported on this platform.

strange. Let me check.

[while compiling compiler-rt/lib/dfsan/lit_tests/Output/custom.c]
clang-3.4: error: unsupported option '-fsanitize=dataflow' for target
'powerpc64-unknown-linux-gnu'

same as tsan/msan, I guess.

So, shall I completely disable compiler-rt for PPC64/Linux?

I'd like to keep asan tests on PowerPC64.
they are not particularly green today, but better than nothing.
You can of course disable compiler-rt in your testing process on
PPC64/Linux.
