Any chance you could do a test run with 7.0.1 as well? This doesn't look like a regression but still worth confirming.
Reported upstream.
Could you try running the clang invocation from the test manually, and adding -v to see the include paths it's using?
(per https://bugs.llvm.org/show_bug.cgi?id=40821#c2)
Hmm, alternatively: ebuild clang-8.0.0_rc2.ebuild compile Then check if the following directory (or equivalent for your PORTAGE_TMPDIR) contains stdint.h: /var/tmp/portage/sys-devel/clang-9999/work/lib/clang/9.0.0/include Then try making test.c with: #include <arm_fp16.h> And running it via just-built clang: /var/tmp/portage/sys-devel/clang-9999/work/x/y/clang-9999-*/bin/clang -v -fsyntax-only -ffreestanding --target=aarch64-none-eabi -march=armv8.2-a+fp16 -std=c89 -xc -E test.c The output should use headers from /var/tmp, e.g.: # 1 "test.c" 2 # 1 "/var/tmp/portage/sys-devel/clang-9999/work/x/y/clang-9999-abi_x86_64.amd64/bin/../../../../lib/clang/9.0.0/include/arm_fp16.h" 1 3 4 # 27 "/var/tmp/portage/sys-devel/clang-9999/work/x/y/clang-9999-abi_x86_64.amd64/bin/../../../../lib/clang/9.0.0/include/arm_fp16.h" 3 4 # 1 "/var/tmp/portage/sys-devel/clang-9999/work/x/y/clang-9999-abi_x86_64.amd64/bin/../../../../lib/clang/9.0.0/include/stdint.h" 1 3 4 # 107 "/var/tmp/portage/sys-devel/clang-9999/work/x/y/clang-9999-abi_x86_64.amd64/bin/../../../../lib/clang/9.0.0/include/stdint.h" 3 4

Created attachment 584132 [details] build.log.xz (ppc64, clang-8.0.1) clang-8.0.1 still affected on ppc64.

Had an interesting chat about this problem on #talos-workstation asking if it is seen on other distros too. Got a hint, that the testsuite passes on Adelie Linux. Also someone else pointed out that such errors specifically may happen on non-multilib systems: "Are you per chance running pure 64-bit? Because that might be one reason that 32 bit headers would be missing and exposing this problem. [...] in any case, the error signifies that a 32 bit build is being done without 32 bit headers available. It's possible that the test only works elsewhere because most distros install the 32 bit headers. It's *still* the wrong headers even in that case though. [...] Well, the real problem is that tests like that shouldn't be using system include paths in the first place, unless they are specifically being built to run on the build machine. And if they *ARE* being built to run on the build machine, then there is leakage going on ending up in stuff getting set as if it were going to be a 32 bit build. [...] https://gcc.gnu.org/wiki/FAQ#gnu_stubs-32.h" As I am in no way an expert on compilers I just re-post this information here, hoping it may provide some insight, if not already known.
Created attachment 584670 [details] build.log.xz (ppc, clang-8.0.1) Out of curiosity I built clang on ppc, which passes all tests there, including Clang :: Headers/arm-fp16-header.c Clang :: Headers/arm-neon-header.c
Both tests pass in sys-devel/clang-9.0.0 on ppc64. @tka, how about your amd64 box?
Ah, from your build.log in bug #695412 I worked out they pass on your amd64 box too. So I will close this one.
