[PATCH] D37405: [safestack] Experimental mode where stack pointer is accessed with a function call.

[Evgenii Stepanov via Phabricator via llvm-commits]

eugenis added a comment.

The function should really have coldcc or preserve_allcc but those are either not implemented (i.e. crash the compiler) or just not do anything useful on arm and aarch64.
As is, generated code is atrocious.
