When pointer authentication is enabled, some upper bits of the link register (LR[63:VA_SIZE]) are used to store a signature. Therefore, GDB need to remove the signature to get backtraces. GDB has support of pointer authentication. When pointer authenticaion is enabled, GDB requests 8-bytes mask to the target to remove the signature. mask[63:VA_SIZE] should be all set and mask[VA_SIZE-1:0] should be all cleared. GDB removes the signature by addr&~mask or addr|mask. I added a feature to provide the mask for pointer authentication.
