Binutils with MCST patches
df6780137d
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 following BFloat16 instructions to the aarch64 backend: bfdot, bfmmla, bfcvt, bfcvtnt, bfmlal[t/b], bfcvtn2. Committed on behalf of Mihail Ionescu. gas/ChangeLog: 2019-11-07 Mihail Ionescu <mihail.ionescu@arm.com> 2019-11-07 Matthew Malcomson <matthew.malcomson@arm.com> * config/tc-aarch64.c (vectype_to_qualifier): Special case the S_2H operand qualifier. * doc/c-aarch64.texi: Document bf16 and bf16mmla4 extensions. * testsuite/gas/aarch64/bfloat16.d: New test. * testsuite/gas/aarch64/bfloat16.s: New test. * testsuite/gas/aarch64/illegal-bfloat16.d: New test. * testsuite/gas/aarch64/illegal-bfloat16.l: New test. * testsuite/gas/aarch64/illegal-bfloat16.s: New test. * testsuite/gas/aarch64/sve-bfloat-movprfx.s: New test. * testsuite/gas/aarch64/sve-bfloat-movprfx.d: New test. include/ChangeLog: 2019-11-07 Mihail Ionescu <mihail.ionescu@arm.com> 2019-11-07 Matthew Malcomson <matthew.malcomson@arm.com> * opcode/aarch64.h (AARCH64_FEATURE_BFLOAT16): New feature macros.

(BFLOAT_SVE_INSN, BFLOAT_BFMMLA4_INSN, BFLOAT_INSN): New macros to define BFloat16 instructions. (aarch64_opcode_table): Define new instructions bfdot, bfmmla, bfcvt, bfcvtnt, bfdot, bfdot, bfcvtn, bfmlal[b/t] bfcvtn2, bfcvt. Regression tested on aarch64-elf. Is it ok for trunk?

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
