unsigned getCheckerSizeInBytes(AuthCheckMethod Method)
Returns the number of bytes added by checkAuthenticatedRegister.
AuthCheckMethod
Variants of check performed on an authenticated pointer.

@ XPACHint
Check by comparing the authenticated value with an XPAC-ed one without using PAuth instructions not e...
Definition AArch64PointerAuth.h:75
@ DummyLoad
Perform a load to a temporary register.
Definition AArch64PointerAuth.h:49
@ HighBitsNoTBI
Check by comparing bits 62 and 61 of the authenticated address.
Definition AArch64PointerAuth.h:59
@ None
Do not check the value at all.
Definition AArch64PointerAuth.h:46
@ XPAC
Similar to XPACHint but using Armv8.3-only XPAC instruction, thus not restricted to LR:
Definition AArch64PointerAuth.h:85
This is an optimization pass for GlobalISel generic memory operations.
