Intel AVX512 FP16 instructions use maps 3, 5 and 6. Maps 5 and 6 use 3 bits in the EVEX.mmm field (0b101, 0b110). Map 5 is for instructions that were FP32 in map 1 (0Fxx). Map 6 is for instructions that were FP32 in map 2 (0F38xx). There are some exceptions to this rule. Some things in map 1 (0Fxx) with imm8 operands predated our current conventions; those instructions moved to map 3. FP32 things in map 3 (0F3Axx) found new opcodes in map3 for FP16 because map3 is very sparsely populated. Most of the FP16 instructions share opcodes and prefix (EVEX.pp) bits with the related FP32 operations. Intel AVX512 FP16 instructions has new displacements scaling rules, please refer to the public software developer manual for detail information. gas/ 2021-08-05 Igor Tsimbalist <igor.v.tsimbalist@intel.com> H.J.

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.
