Guarded Control Stack Pop loads the 64-bit doubleword that is pointed to by the current Guarded control stack pointer, writes it to the destination register, and increments the current Guarded control stack pointer register by the size of a Guarded control stack procedure return record.
This is an alias of SYSL. This means:
| 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 | 0 | 1 | 0 | 1 | 0 | 0 | 1 | 0 | 1 | 0 | 1 | 1 | 0 | 1 | 1 | 1 | 0 | 1 | 1 | 1 | 0 | 0 | 1 | Rt | ||||
| L | op1 | CRn | CRm | op2 | |||||||||||||||||||||||||||
| <Xt> |
Is the 64-bit name of the optional general-purpose destination register, encoded in the "Rt" field. Defaults to XZR if absent. |
The description of SYSL gives the operational pseudocode for this instruction.
