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

[Leonard Chan via Phabricator via llvm-commits]

@pcc Do you happen to have a list of platforms that you suspect use libgcc and will break with this CFI? If this is a bug compatibility issue, we're thinking that instead of just disabling this for everyone, we should instead disable it for a blacklisted set of targets. So all targets by default would go through this branch except for those that actively crash from this.
