;; Backport z15 record/replay
;; Andreas Arnaz, RH BZ 1659535
commit 6d9d6da48e84a65871a9d72fa785105d603990a6
Author: Andreas Arnez <arnez@linux.ibm.com>
Date: Wed Oct 9 11:09:22 2019 +0200
s390: Add record/replay support for arch13 instructions
Enable recording most of the new "arch13" instructions on z/Architecture
targets, except for the specialized-function-assist instructions:
SORTL - sort lists
DFLTCC - deflate conversion call
KDSA - compute digital signature authentication
gdb/ChangeLog:
* s390-tdep.c (390_process_record): Handle new arch13 instructions
except SORTL, DFLTCC, and KDSA.
