[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

(Haven't looked carefully ) but the Pipeline model: matches AArch64 (ideal model in my view https://community.arm.com/arm-community-blogs/b/tools-software-ides-blog/posts/compiler-flags-across-architectures-march-mtune-and-mcpu)
(I probably need to update my https://maskray.me/blog/2022-08-28-march-mcpu-mtune)

"Architecture extension has quite complicated behavior now:" looks too complex.
