Unable to build Handbrake with llvm-15/clang-15 on linux

Problem Description

Unable to build Handbrake with llvm-15/clang-15 on linux.

I'm able to build it without problems on llvm-14/clang-14 on linux.

I'm building to generate FDO/PGO data

These are my build options in the custom.defs file:
GCC.args.O.speed = -fasynchronous-unwind-tables -fno-semantic-interposition -fno-trapping-math -ffat-lto-objects -march=native -mtune=native -pipe -O3
GCC.args.extra = -w -feliminate-unused-debug-types -fstack-protector-strong -fstack-clash-protection -D_FORTIFY_SOURCE=2 -fPIE -pie -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now -Wp,-D_GLIBCXX_ASSERTIONS -fprofile-instr-generate=<path-hidden>/HandBrake/clangFDO/default_%m.profraw -fprofile-update=atomic -flto=thin

This is my build command line:
LDFLAGS="-fuse-ld=lld" ./configure --ld /usr/bin/ld.lld --ar /usr/bin/llvm-ar --ranlib /usr/bin/llvm-ranlib --strip /usr/bin/llvm-strip --cc /usr/bin/clang --optimize=speed --enable-fdk-aac --disable-nvenc --build=build-v1.5.1-CLANG && cd ./build-v1.5.1-CLANG && time LDFLAGS="-fuse-ld=lld" make -j$(( $(nproc) + 2 ));

With llvm-14 and clang-14 as mentioned, I can build smoothly using the options and command line above.
However with version 15 I get the following errors:
bfd plugin: LLVM gold plugin has failed to create LTO module: Not an int attribute (Producer: 'LLVM15.0.3' Reader: 'LLVM 13.0.1') LLVM ERROR: Type mismatch in constant table!

Also not sure why bfd plugin is triggering the use of the gold linker. I've explicitly added "-fuse-ld=lld".
Any help here would be greatly appreciated thanks in advance!

Activity Log, Crash Log or any other details

This reminds me to the Clang error I'm seeing if I try to build with -flto=thin on macOS with current Xcode. If its the same reason, then its because x264 does set -mstack-alignment=64 in configure, FFmpeg does set -mstack-alignment=16 and this seems to be a conflict when linking. There was a change in the recent Clang/LLVM which does makes this now an error.

Can you try to build with your build options and build commands from this branch:
https://github.com/Nomis101/HandBrake/tree/mstack-test

It this does fix your issue, it is the same reason, if not, its a different one.

May very well be!
I can't build with the fork atm as I'm in the midst of doing a FDO generation of several videos of various qualities with llvm-14. Takes several days.
Once done I'll try llvm-15 again.

If it does the trick then perhaps you should try and get it into upstream to at least get the discussion going.

Still relevant ?
