[PATCH] D73070: Add function attribute "patchable-function-prefix" to support -fpatchable-function-entry=N,M where M>0

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

-fpatchable-function-entry=N,M (where M>0) + -mbranch-protection=bti is quite clear (https://gcc.gnu.org/ml/gcc-patches/2020-01/msg01185.html).

For -fpatchable-function-entry=N,0 + -mbranch-protection=bti/-fcf-protection=branch, if you have preference for placement (a) or (b), please make a comment:) and/or reply at https://gcc.gnu.org/ml/gcc-patches/2020-01/msg01185.html
If you are not subscribed to the gcc-patches mailing list (like me), you will have to download the raw email file `Other format:	[Raw text]` and reply...

(b) will require separate patches.
