@Crivella could you maybe take a look? The full log can be found at /project/def-users/SHARED/build-logs/jobs/188050/easybuild-5apt_nb3.log on the AWS cluster.

It seems all the failures are of the type

Using __unused seems to be allowed on FreeBSD and ANDROID

i guess we could add an EESSI specific patch where we add an && false to that section?

We could also ignore those tests (would be the same as the proposed patch), trying to understand the implications.

It seems they were introduced to avoid errors of the type llvm/llvm-project#161808

From what i can tell this tests are checking that LLVM code itself is not using system reserved names.
In our case the definition is coming not from LLVM itself but from the chain of includes related to stdlib.h in our compat layer so it should be safe to ignore this

According to an AI friend, glibc 2.43 (which we use) initially shipped with __unused, but this was later changed to __glibc_reserved. Slightly newer revisions of Gentoo's ebuild file for 2.43 (r3, we have r2) also use a patch 0039-Rename-__unused-fields-to-__glibc_reserved.patch that probably solves this. But in order to apply that, we would have to recompile glibc.

Those test are to protect against breaking user code or system code that might be using those defines (as far as i understand).

Since __unused is coming from our glibc it should not be breaking system code, i guess the only worry is if we risk breaking user code that uses #define __unused

So should be safe to ignore for LLVM itself, we just need to decide if we want to rebuild glibc or ignore them.

Concerning the other tests we can most likely safely ignore also:

  •       FAIL: Clang :: Driver/aarch64-toolchain-extra.c (11928 of 108545)
      FAIL: Clang :: Driver/arm-toolchain-extra.c (12048 of 108545)

    This should be cross-compiling toolchain which do not seem like they are failing but just giving slightly different verbose output than expected (potentially due to the sysroot but would need to verify)

  •       FAIL: libFuzzer-x86_64-default-Linux :: stack-overflow-with-asan.test (90568 of 108545)
      FAIL: libFuzzer-x86_64-libcxx-Linux :: stack-overflow-with-asan.test (90703 of 108545)
      FAIL: libFuzzer-x86_64-static-libcxx-Linux :: stack-overflow-with-asan.test (90843 of 108545)

    Here we are not hitting an expected stack overflow, but i am not sure if this is really a problem

The others are related to LLVM tooling and i think we already hit some of them in 20.1.8 on EESSI but decided we were fine with them.

I would probably just add an hook that adds these to the ignored tests for our LLVM 21.1.8 builds
