[PATCH 37/46] s390: Add .insn pseudo-mnemonic smi
This patch introduces support for the SMI instruction format, which was introduced with the IBM zEC12 processor, into the s390 assembler using the .insn pseudo-mnemonic. It requires the respective minimum architecture or CPU level. The changes involve adding the format to s390-opc.c, documenting it in gas/doc/c-s390.texi, and adding corresponding tests in the gas testsuite.
