A mistake with rebasing the ARMv8.2 AT instruction patch left this part + /* AT S1E1RP, AT S1E1WP. Values are from aarch64_sys_regs_at. */ + if ((reg->value == CPENS (0, C7, C9, 0) + || reg->value == CPENS (0, C7, C9, 1)) + && !AARCH64_CPU_HAS_FEATURE (features, AARCH64_FEATURE_V8_2)) + return FALSE; in aarch64_pstatefield_supported_p rather than in aarch64_sys_ins_reg_supported_p, where it was supposed to be. The patch adding support for id_aa64mmfr2_el1, also had the effect of removing a conditional branch in aarch64_sys_reg_supported_p. The effect of both of these is to suppress an error if some ARMv8.2 system registers are used with the wrong -march settings. This patch fixes these mistakes. opcodes/ 2015-12-14 Matthew Wahab <matthew.wahab@arm.com> * aarch64-opc.c (aarch64_sys_reg_supported_p): Add mistakenly removed statement. (aarch64_pstatefield_supported_p): Move feature checks for AT registers .. (aarch64_sys_ins_reg_supported_p): .. to here. Change-Id: I48783d118eaaf0f3312e8b08a8340ef7af4e36a4 |

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.
