[PATCH] D143235: [AArch64] Avoid lowering setjmp call to CALL_BTI if harden-sls-blr is enabled

[David Spickett via Phabricator via llvm-commits]

DavidSpickett added a comment.

Not crashing seems reasonable :)

I don't know what the interaction of BTI and the sls-blr is though. Does not emitting the bti actually break things if you have sls-blr and branch target enforcement enabled? Perhaps the `__llvm_slsblr_thunk_x` would make that all work because it would contain the required btis.

I defer to @kristof.beyls on that one.
