The Binutils assembler (gas) now supports the IBM z13’s stcctm (store CPU counter multiple) instruction. This instruction is part of the CPU-Measurement Facilities (CPUMF). The change also adds comments to existing CPUMF instructions in the opcode table and includes new test cases for the stcctm instruction.
