This patch removes the vx2 facility flag. It will not be used by GCC and was a misnomer anyway. Committed to mainline and 2.28 branch. include/ChangeLog: 2017-03-21 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * opcode/s390.h (S390_INSTR_FLAG_VX2): Remove. (S390_INSTR_FLAG_FACILITY_MASK): Adjust value. gas/ChangeLog: 2017-03-21 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * config/tc-s390.c (s390_parse_cpu): Remove S390_INSTR_FLAG_VX2 from cpu_table. Remove vx2, and novx2 from cpu_flags. opcodes/ChangeLog: 2017-03-21 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * s390-mkopc.c (main): Remove vx2 check. * s390-opc.txt: Remove vx2 instruction flags.
