=== Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to add support for ARMv8-R in GAS: instructions, build attributes and readelf. === Patch description === Although some differences exist for system registers, from GAS point of view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state and a subset of its extensions. This patch therefore introduce a new feature bit to distinguish the availability of the pan, ras and rdma extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd extensions to be used by ARMv8-R. Most of the changes are then in the testsuite to (i) rename source files and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename files with expected output for ARMv8-A build attributes and (iii) add new files with expected output for ARMv8-R build attributes. 2017-06-24 Thomas Preud'homme <thomas.preudhomme@arm.com> binutils/ * readelf.c (arm_attr_tag_CPU_arch): Fill value for ARMv8-R. gas/ * NEWS: Mention support for ARMv8-R architecture. * config/tc-arm.c (arm_archs): Add entry for ARMv8-R.

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.
