Created attachment 688872 [details] llvm-11.0.1:20210301-095647.log.gz When I compiled llvm with gcc all tests ran fine.

What's your current libc++ version? Could you try installing the new one (with 'untested' LLVM) and then trying to rebuild LLVM with tests?

Nah, I meant 11.0.1. So it's not a version incompatibility.
I'm afraid I can't help you here, unless you are able to figure it out yourself. A good first step would be to try to reproduce with 13.0.0.9999. You may want to choose a single revision and set EGIT_COMMIT for all packages to avoid inconsistency-due-to-fetch-delay.
With 13.0.0.9999 (Commit 955365524aeea122243cb8ef201cd2687e7694b4) and corresponding libcxx and libcxxabi, I get: ******************** Failed Tests (14): LLVM-Unit :: IR/./IRTests/CGSCCCallbacksTest.InstrumentedInvalidatingPasses LLVM-Unit :: IR/./IRTests/CGSCCCallbacksTest.InstrumentedPasses LLVM-Unit :: IR/./IRTests/CGSCCCallbacksTest.InstrumentedSkippedPasses LLVM-Unit :: IR/./IRTests/FunctionCallbacksTest.InstrumentedPasses LLVM-Unit :: IR/./IRTests/FunctionCallbacksTest.InstrumentedSkippedPasses LLVM-Unit :: IR/./IRTests/LoopCallbacksTest.InstrumentedInvalidatingLoopNestPasses LLVM-Unit :: IR/./IRTests/LoopCallbacksTest.InstrumentedInvalidatingPasses LLVM-Unit :: IR/./IRTests/LoopCallbacksTest.InstrumentedPasses LLVM-Unit :: IR/./IRTests/LoopCallbacksTest.InstrumentedSkippedPasses LLVM-Unit :: IR/./IRTests/ModuleCallbacksTest.InstrumentedSkippedPasses LLVM :: ExecutionEngine/MCJIT/eh-lg-pic.ll LLVM :: ExecutionEngine/MCJIT/eh.ll LLVM :: ExecutionEngine/MCJIT/multi-module-eh-a.ll LLVM :: ExecutionEngine/MCJIT/remote/eh.ll So half of the problem has been 'solved', but new failures have emerged. Unless you have new suggestions, I think I'll stop here, I don't have the skills to go any further on my own. Thanks anyway.
As I said, I'm currently unable to dedicate any time into this. We don't really have the capacity to provide first-class support for clang builds with all their intricacies and the problem is really hard because clang's Linux backend is basically a big heap of hacks for different setups. I'm not going to ask you to dig any further. If you even managed to find the root cause, I can't give you any guarantees that someone will fix it upstream. This could also be related to your CFLAGS.
