This patch makes changes to the <spec_reg> operand for VMRS and VMSR instructions as per the Armv8.1-M Mainline. New <spec_reg> options to support are: 0b0010: FPSCR_nzcvqc, access to FPSCR condition and saturation flags. 0b1100: VPR, privileged only access to the VPR register. 0b1101: P0, access to VPR.P0 predicate fields 0b1110: FPCXT_NS, enables saving and restoring of Non-secure floating point context. 0b1111: FPCXT_S, enables saving and restoring of Secure floating point context *** gas/ChangeLog *** 2019-05-21 Sudakshina Das <sudi.das@arm.com> * config/tc-arm.c (parse_operands): Update case OP_RVC to parse p0 and P0. (do_vmrs): Add checks for valid operands with respect to cpu and fpu options. (do_vmsr): Likewise. (reg_names): New reg_names for FPSCR_nzcvqc, VPR, FPCXT_NS and FPCXT_S. * testsuite/gas/arm/armv8_1-m-spec-reg.d: New. * testsuite/gas/arm/armv8_1-m-spec-reg.s: New. * testsuite/gas/arm/armv8_1-m-spec-reg-bad1.d: New. * testsuite/gas/arm/armv8_1-m-spec-reg-bad2.d: New. * testsuite/gas/arm/armv8_1-m-spec-reg-bad3.d: New. * testsuite/gas/arm/armv8_1-m-spec-reg-bad1.l: New. * testsuite/gas/arm/armv8_1-m-spec-reg-bad2.l: New. * testsuite/gas/arm/armv8_1-m-spec-reg-bad3.l: New. * testsuite/gas/arm/vfp1xD.d: Updated to allow new valid values. * testsuite/gas/arm/vfp1xD_t2.d: Likewise. *** opcodes/ChangeLog *** 2019-05-21 Sudakshina Das <sudi.das@arm.com> * arm-dis.c (coprocessor_opcodes): New instructions for VMRS and VMSR with the new operands. |

README
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.
