+// These pointer authentication instructions require armv8.3a
+let Predicates = [HasV8_3a, HasPA] in {
let Uses = [LR], Defs = [LR] in {
def PACIAZ : SystemNoOperands<0b000, "hint\t#24">;
def PACIBZ : SystemNoOperands<0b010, "hint\t#26">;
let isAuthenticated = 1 in {
def AUTIAZ : SystemNoOperands<0b100, "hint\t#28">;
----------------
IIRC these instructions are deliberately allowed in pre-armv8.3 targets because
they are encoded in the NOP-space and can be deployed on pre-armv8.3 targets
