Interesting.

I'll note that the likes of -march=3Dx86-64-v2 was added in 2020-Oct
for gcc/g++ and clang/clang++ so older notes would not reference
the possibility.

It is associated with:

https://gitlab.com/x86-psABIs/x86-64-ABI/-/commit/77566eb03bc6a326811cb7e9a=
6b9396884b67c7c

For all I know it may have the same issues for lock free code
in the tool chains.
