2021-11-17 Jim Wilson <jimw@sifive.com> Kito Cheng <kito.cheng@sifive.com> Nelson Chu <nelson.chu@sifive.com> This patch is porting from the following riscv github, https://github.com/riscv/riscv-binutils-gdb/tree/rvv-1.0.x And here is the vector spec, https://github.com/riscv/riscv-v-spec bfd/ * elfxx-riscv.c (riscv_implicit_subsets): Added imply rules of v, zve and zvl extensions. (riscv_supported_std_ext): Updated verison of v to 1.0. (riscv_supported_std_z_ext): Added zve and zvl extensions. (riscv_parse_check_conflicts): The zvl extensions need to enable either v or zve extension. (riscv_multi_subset_supports): Check the subset list to know if the INSN_CLASS_V and INSN_CLASS_ZVEF instructions are supported. gas/ * config/tc-riscv.c (enum riscv_csr_class): Added CSR_CLASS_V. (enum reg_class): Added RCLASS_VECR and RCLASS_VECM. (validate_riscv_insn): Check whether the rvv operands are valid. (md_begin): Initialize register hash for rvv registers. (macro_build): Added rvv operands when expanding rvv pseudoes. (vector_macro): Expand rvv macros into one or more instructions. (macro): Likewise. (my_getVsetvliExpression): Similar to my_getVsetvliExpression, but used for parsing vsetvli operands. (riscv_ip): Parse and encode rvv operands. Besides, The rvv loads and stores with EEW 64 cannot be used when zve32x is enabled. * testsuite/gas/riscv/priv-reg-fail-version-1p10.d: Updated -march to rv32ifv_zkr. * testsuite/gas/riscv/priv-reg-fail-version-1p11.d: Likewise. * testsuite/gas/riscv/priv-reg-fail-version-1p9p1.d: Likewise. * testsuite/gas/riscv/priv-reg.s: Added rvv csr testcases. * testsuite/gas/riscv/priv-reg-version-1p10.d: Likewise. * testsuite/gas/riscv/priv-reg-version-1p11.d: Likewise. * testsuite/gas/riscv/priv-reg-version-1p9p1.d: Likewise. * testsuite/gas/riscv/march-imply-v.d: New testcase. * testsuite/gas/riscv/vector-insns-fail-zve32xf.d: Likewise. * testsuite/gas/riscv/vector-insns-fail-zve32xf.l: Likewise. * testsuite/gas/riscv/vector-insns-fail-zvl.d: Likewise. * testsuite/gas/riscv/vector-insns-fail-zvl.l: Likewise. * testsuite/gas/riscv/vector-insns-vmsgtvx.d: Likewise. * testsuite/gas/riscv/vector-insns-vmsgtvx.s: Likewise. * testsuite/gas/riscv/vector-insns-zero-imm.d: Likewise. * testsuite/gas/riscv/vector-insns-zero-imm.s: Likewise. * testsuite/gas/riscv/vector-insns.d: Likewise. * testsuite/gas/riscv/vector-insns.s: Likewise. include/ * opcode/riscv-opc.h: Defined mask/match encodings and csrs for rvv. * opcode/riscv.h: Defined rvv immediate encodings and fields. (enum riscv_insn_class): Added INSN_CLASS_V and INSN_CLASS_ZVEF. (INSN_V_EEW64): Defined. (M_VMSGE, M_VMSGEU): Added for the rvv pseudoes. opcodes/ * riscv-dis.c (print_insn_args): Dump the rvv operands. * riscv-opc.c (riscv_vecr_names_numeric): Defined rvv registers. (riscv_vecm_names_numeric): Likewise. (riscv_vsew): Likewise. (riscv_vlmul): Likewise. (riscv_vta): Likewise. (riscv_vma): Likewise. (match_vs1_eq_vs2): Added for rvv Vu operand. (match_vd_eq_vs1_eq_vs2): Added for rvv Vv operand. (riscv_opcodes): Added rvv v1.0 instructions. |

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.
