ARMv8.2 adds 16-bit floating point operations as an optional extension to floating point and Adv.SIMD support. This patch set adds the 16-bit Adv.SIMD vector and scalar instructions to binutils, making them available when both +simd and +fp16 architecture extensions are enabled. The series also adds support for a new vector type, 2H, used by the FP16 scalar pairwise instructions. The patches in this series: - Add a FP16 Adv.SIMD feature macro for use by the encoding/decoding routines. - Add FP16 instructions in the group Vector Three Register Same. - Add FP16 instructions in the group Scalar Three Register Same. - Add FP16 instructions in the group Vector Two Register Misc. - Add FP16 instructions in the group Scalar Two Register Misc. - Add FP16 instructions in the group Vector Indexed Element. - Add FP16 instructions in the group Scalar Indexed Element. - Add FP16 instructions in the group Adv.SIMD Across Lanes. - Add FP16 instructions in the group Adv.SIMD Modified Immediate. - Rework some code for handling vector types to weaken its assumptions about available vector-types. - Add support for the 2H vector type. - Add FP16 instructions in the group Adv.SIMD Scalar Pairwise. - Add FP16 instructions in the group Adv.SIMD Shift By Immediate. - Add a FP16 instructions in the group Adv.SIMD Scalar Shift By Immediate. This patch adds the feature macro SIMD_F16 to the AArch64 encoding/decoding routines. It is used to decide when the new instructions are available to the assembler and is true when both +simd and +fp16 are selected. opcodes/ 2015-12-14 Matthew Wahab <matthew.wahab@arm.com> * aarch64-tbl.h (aarch64_feature_simd_f16): New.

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.
