[Patch][binutils][arm] Armv8.6-A Matrix Multiply extension [9/10]
Hi,
This patch is part of a series that adds support for Armv8.6-A
(Matrix Multiply and BFloat16 extensions) to binutils.
This patch introduces the Matrix Multiply (Int8, F32, F64) extensions
to the arm backend.
The following Matrix Multiply instructions are added: vummla, vsmmla,
vusmmla, vusdot, vsudot[1].

(do_vummla): New.
(insns): Add vsmmla, vummla, vusmmla, vusdot, vsudot mnemonics.
(armv86a_ext_table): Add i8mm extension.
(arm_extensions): Move bf16 extension to context sensitive table.
(armv82a_ext_table, armv84a_ext_table, armv85a_ext_table):
Move bf16 extension to context sensitive table.
(armv86a_ext_table): Add i8mm extension.
* doc/c-arm.texi: Document i8mm extension.
* testsuite/gas/arm/i8mm.s: New test.
* testsuite/gas/arm/i8mm.d: New test.
* testsuite/gas/arm/bfloat17-cmdline-bad-3.d: Update test.
include/ChangeLog:
2019-11-07 Mihail Ionescu <mihail.ionescu@arm.com>
* opcode/arm.h (ARM_EXT2_I8MM): New feature macro.
opcodes/ChangeLog:
2019-11-07 Mihail Ionescu <mihail.ionescu@arm.com>
* arm-dis.c (neon_opcodes): Add i8mm SIMD instructions.
Regression tested on arm-none-eabi.
Is this ok for trunk?
