The Statistical Profile Extension adds the instruction PSB CSYNC as an alias for the HINT #17 instruction. This patch adds the instruction to binutils as a HINT alias that takes an operand. A new operand type, AARCH64_OPND_BARRIER_PSB, is added to represent the operand to PSB. A parser for the operand type is added to the assembler and a printer to the disassembler. The operand name "csync" is added to the list of HINT options with HINT number #17. Encoding and decoding of the operand is handled by the ins_hint/ext_hint functions added in the preceding patches. gas/ 2015-12-11 Matthew Wahab <matthew.wahab@arm.com> * config/tc-aarch64.c (aarch64_hint_opt_hsh): New. (parse_barrier_psb): New. (parse_operands): Add case for AARCH64_OPND_BARRIER_PSB.

Update the expected output. * gas/aarch64/system-2.s: Add tests for PSB CSYNC. * gas/aarch64/system.d: Update the expected output. include/opcode/ 2015-12-11 Matthew Wahab <matthew.wahab@arm.com> * aarch64.h (aarch64_opnd): Add AARCH64_OPND_BARRIER_PSB. * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Regenerate. * aarch64-opc-2.c: Regenerate. * aarch64-opc.c (aarch64_hint_options): Add "csync".

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.
