[PATCH] D72215: [AArch64] Add function attribute "patchable-function-entry" to add NOPs at function entry

[Fangrui Song via Phabricator via llvm-commits]

MaskRay updated this revision to Diff 236772.
MaskRay added a comment.

I think GCC's __patchable_function_entries has severe design flaws.
I try to address these problems.

Will update this comment soon.
