[PATCH 14/46] s390: Add .insn pseudo-mnemonic mii
This patch adds the ‘.insn mii’ pseudo-mnemonic to the GNU Assembler for the s390 architecture. It reflects the MII instruction format, which was introduced with the IBM zEC12 processor. The changes include updates to the opcode definitions and documentation, along with new test cases for z/Architecture.
