<pre>Assembly files should not be compiled as C and instead use CMake's assembly
language support to allow for vendors and users to specify flags, compiler
options, use a different executable, have correct architecture flags, interact
properly with toolchain files, etc.
The compiler-rt ARM64 outline atomic helpers are a new and the only case of
this improper usage in the codebase.
It seems these should use the already-existing compiler-rt add_asm_sources()
helper.
Previous occurrences of this were fixed by
<a href="https://github.com/llvm/llvm-project/commit/45344cf7ac5b848f77825ffa37b0cb3b69b9b07b">https://github.com/llvm/llvm-project/commit/45344cf7ac5b848f77825ffa37b0cb3b69b9b07b</a>.
The improper usage resulted in multiple reports from users and vendors,
requiring a backport to resolve build issues.
It would be best to avoid a recurrence of the problems. Marking as a release
blocker due to this.
Pavel, could you take a look at this?</pre>
