In fact rev8/orc.b/zext.h are the aliases of grevi/gorci/pack[w], so we should update them to INSN_ALIAS when we have supported their true instruction in the future. Though we still use the [MATCH|MAKS]_[GREVI|GORCI|PACK|PACKW] to encode them. Besides, the orc.b has the same encoding both in rv32 and rv64, so we just keep one of them in the opcode table. This patch is implemented according to the following link, https://github.com/riscv/riscv-bitmanip/pull/101 2021-01-07 Claire Xenia Wolf <claire@symbioticeda.com> Jim Wilson <jimw@sifive.com> Andrew Waterman <andrew@sifive.com> Maxim Blinov <maxim.blinov@embecosm.com> Kito Cheng <kito.cheng@sifive.com> Nelson Chu <nelson.chu@sifive.com> bfd/ * elfxx-riscv.c (riscv_std_z_ext_strtab): Added zba, zbb and zbc. gas/ * config/tc-riscv.c (riscv_multi_subset_supports): Handle INSN_CLASS_ZB*. (riscv_get_default_ext_version): Do not check the default_isa_spec when the version defined in the riscv_opcodes table is ISA_SPEC_CLASS_DRAFT. * testsuite/gas/riscv/bitmanip-insns-32.d: New testcase. * testsuite/gas/riscv/bitmanip-insns-64.d: Likewise. * testsuite/gas/riscv/bitmanip-insns.s: Likewise. include/ * opcode/riscv-opc.h: Added MASK/MATCH/DECLARE_INSN for ZBA/ZBB/ZBC. * opcode/riscv.h (riscv_insn_class): Added INSN_CLASS_ZB*.

(MASK_RVB_IMM): Used for rev8 and orc.b encoding. |

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.
