This is on a 64-bit PowerPC (Power9) in big endian mode, running musl libc on Linux 5.15. Note that this is a Debug build with -DLLVM_ENABLE_ASSERTIONS=ON; in Release mode without assertions, I receive no assertion failure but a failed test case ("error: -: The file was not recognized as a valid object file").

Additionally, the Release build shows two failures that are not present in the Debug build, both of which are segmentation faults without backtraces, i.e.:

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.

In Release mode, there is an additional case that does not trigger under Debug with assertions on. Unfortunately, since I can't seem to trigger it in Debug, all I can provide is the backtrace from the signal handler.

Interestingly, on a SPARC system with 'Sparc;X86' as enabled targets, I only see:

Failed Tests (3):
  LLVM-Unit :: tools/llvm-exegesis/./LLVMExegesisTests/SubprocessMemoryTest/DefinitionFillsCompletely
  LLVM-Unit :: tools/llvm-exegesis/./LLVMExegesisTests/SubprocessMemoryTest/MultipleDefinitions
  LLVM-Unit :: tools/llvm-exegesis/./LLVMExegesisTests/SubprocessMemoryTest/OneDefinition

…which means somehow this is specific to PPC64, and not endian-related?

awilfox commented 3 months ago

For what it's worth, running another LLVM 18 build on PPC64 yielded a failure in one of the tests I hadn't disabled - so maybe it's flaky. I have ensured this isn't hardware related by building on another PPC64 and seeing the same failures.

awilfox commented 2 months ago

ASan showed stack overflow. The problem was that musl's thread stack size defaults to a size too small for LLVM. It'd be advisable to set the stack size manually to ensure it is always sufficient considering different platforms have different stack size defaults for threads.

awilfox commented 2 months ago

Hmm, that made the LTO tests a lot better, but I'm still seeing a few of the dwarfutil tests flaking:

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.

We are seeing this on Alpine Linux ppc64le as well, with llvm19.

Good suggestsion. No. it does not appear to make any difference on either ppc64le or armhf (armv6). At least not tor the odr-string.test.

I also have this applied to always set a larger stack size:

I think various tests are flakyon ppc64le. This is the failing tests:

Ok. I'm trying to focus on odr-string.test now, on ppc64le. It is definitively flaky.

Rerunning this will often, but not always, segfault:

/home/ncopa/aports/main/llvm19/src/llvm-project-19.1.1.src/build/bin/dsymutil --linker=parallel -f -o - -oso-prepend-path=/home/ncopa/aports/main/llvm19/src/llvm-project-19.1.1.src/llvm/test/tools/dsymutil/X86/DWARFLinkerParallel/../ -y /home/ncopa/aports/main/llvm19/src/llvm-project-19.1.1.src/llvm/test/tools/dsymutil/X86/DWARFLinkerParallel/odr-string.test

Here is a backtrace from the core dump:
