Pointer Authentication Code for Data address, using key A. This instruction computes and inserts a pointer authentication code for a data address, using a modifier and key A.
The address is in the general-purpose register that is specified by <Xd>.
The modifier is:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
1 | 1 | 0 | 1 | 1 | 0 | 1 | 0 | 1 | 1 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | Z | 0 | 1 | 0 | Rn | Rd |
PACDZA <Xd>
boolean source_is_sp = FALSE; integer d = UInt(Rd); integer n = UInt(Rn); if !HavePACExt() then UnallocatedEncoding(); if Z == '0' then // PACDA if n == 31 then source_is_sp = TRUE; else // PACDZA if n != 31 then UnallocatedEncoding();
<Xd> | Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field. |
<Xn|SP> | Is the 64-bit name of the general-purpose source register or stack pointer, encoded in the "Rn" field. |
