ARMv8.2 adds 16-bit floating point operations as an optional extension. This patch adjusts the utility function expand_fp_imm to support 16-bit values. The function is intended to convert an 8-bit immediate representing a floating point value to a representation that can be passed to fprintf. Because of the limited use of the results, the only change made to the function is to treat a request for a 16-bit float as a request for a 32-bit float. opcodes/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64-opc.c (half_conv_t): New. (expand_fp_imm): Replace is_dp flag with the parameter size to specify the number of bytes for the required expansion. Treat a 16-bit expansion like a 32-bit expansion. Add check for an unsupported size request. Update comment. (aarch64_print_operand): Update to support 16-bit floating point values. Update for changes to expand_fp_imm.

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.
