S/390: Support vector alignment hints
This patch adds the vector alignment hints to the vector load and
store instructions as documented in the IBM z14 Principles of
Operations manual:
http://publibfi.boulder.ibm.com/epubs/pdf/dz9zr011.pdf
opcodes/ChangeLog:
2018-10-23 Andreas Krebbel <krebbel@linux.ibm.com>
* s390-opc.txt: Add vector load/store instructions with additional
alignment parameter.
gas/ChangeLog:
2018-10-23 Andreas Krebbel <krebbel@linux.ibm.com>
* config/tc-s390.c (md_gather_operands): Fix for optional operands
following memory addresses.
* testsuite/gas/s390/zarch-arch12.d: Add regexp checks for new
instruction variants.
* testsuite/gas/s390/zarch-arch12.s: Emit new instruction
variants.
