I don't know why Group Reviewers libc++ is blocked by Herald.

We already add -Wno-user-defined-literals in libcxx/CMakeLists.txt:576.

Thanks!

It seems that this code does not work correctly. I think we can modify it to suppress the warning in the building stage.

It works in the CI and on my machine, so I suspect it's a problem with your configuration. Maybe the compiler is too old?

Can you elaborate? Do you not see the compile flag passed through correctly when using target_add_compile_flags_if_supported? Considering we use it below and pretty much everywhere else (including other projects in LLVM), I'm a bit suspicious. Can you please explain your use case/specifically what you're doing, and what's not working, so we can best help?
