@efriedma - Do you have access to Windows running on HW that actually supports the PAC instructions? Can you check what happens when unwinding through a call frame that is built with PAC enabled today (where the unwind info lacks the opcode that corresponds to the signing) - does the unwind fail, or does the unwinder leniently strip out the pointer authentication before stepping to the next function?
