So far z15 was identified as arch13. After the machine has been
announced we can now add the real name.

So far we only had an instruction flag which made an arbitrary number
of operands optional. This limits error checking capabilities for
instructions marked that way. With this patch the optparm flag only
allows a single optional parameter and another one is added (optparm2)
allowing 2 optional arguments. Hopefully we won't need more than that
in the future. So far there will be only a single use of optparm2.
gas/ChangeLog:
2017-05-30 Andreas Krebbel <krebbel@linux.vnet.ibm.com>

instruction flag.

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.

gas/ChangeLog:

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.
This adds support of new instructions to the S/390 specific parts.
The important feature of the new instruction set is the support of
single and extended precision floating point vector operations.
Note: arch12 is NOT the official name of the new CPU. It just
continues the series of archXX options supported as alternate names.
The archXX terminology refers to the edition number of the Principle
of Operations manual. The official CPU name will be added later while
keeping support of the arch12 for backwards compatibility.
No testsuite regressions.
Committed to mainline.
Bye,
-Andreas-

This patch adds alternate CPU names which adhere to the number of the
architecture document. So instead of having z196, zEC12, and z13 you
can use arch9, arch10, and arch11. The old cpu names stay valid and
should primarily be used.
The alternate names are supposed to improve compatibility with the IBM
XL compiler toolchain which uses the arch numbering.
