[PATCH] D13132: [X86] Emit .cfi_escape GNU_ARGS_SIZE when adjusting the stack before calls

[Michael Kuperstein via llvm-commits]

mkuper updated this revision to Diff 36229.
mkuper added a comment.

Fixed buffer overflow, and changed the condition to only add GNU_ARGS_SIZE if there are any landing pads in the function.
We can probably do better (by adding them only for invokes), but I'd rather leave that for a separate patch.
