Commit Message

Jens Remus April 24, 2026, 8:40 a.m. UTC 
  IBM z13 introduced the "store CPU counter multiple" (stcctm) instruction
with the Store-CPU-Counter-Multiple Facility, which is part of the
CPU-Measurement Facilities (CPUMF) [1].

While at it add a comment to the s390 opcode table for the existing
CPUMF instructions.

[1]: The Load-Program-Parameter and the CPU-Measurement Facilities,
     SA23-2260-08,
     https://www.ibm.com/docs/en/module_1678991624569/pdf/SA23-2260-08.pdf

opcodes/
	* s390-opc.txt (stcctm): Add store CPU counter multiple
	instruction.  Add comment on CPUMF instructions.

gas/testsuite/
	* gas/s390/zarch-z13.d (stcctm): Add test for store CPU counter
	multiple instruction.
	* gas/s390/zarch-z13.s (stcctm): Likewise.
