[PATCH] D79822: [AArch64] Emit CFI instruction for updating x18 when using ShadowCallStack with exception unwinding

[Roland McGrath via Phabricator via llvm-commits]

mcgrathr added a comment.

glibc on Linux and perhaps other platforms has long implemented pthread_cancel via unwinding, and long supported asynchronous unwinding generally for this.  If LLVM intends to support the Linux glibc ABI, then it must support -fasynchronous-unwind-tables generally.
