GCSPOPX

Guarded Control Stack Pop exception return record loads an exception return record from the location indicated by the current Guarded control stack pointer register, checks that the record is an exception return record, and increments the pointer by the size of a Guarded control stack exception return record.

This is an alias of SYS. This means:
