From 259a2647dc158e196e4e03719cdc6bb0ff657d1d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christoph=20M=C3=BCllner?= Date: Fri, 30 Jun 2023 22:44:05 +0200 Subject: [PATCH] RISC-V: Add support for the Zvksh ISA extension MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Zvksh is part of the vector crypto extensions. This extension adds the following instructions: - vsm3me.vv - vsm3c.vi bfd/ChangeLog: * elfxx-riscv.c (riscv_multi_subset_supports): Add instruction class support for Zvksh. (riscv_multi_subset_supports_ext): Likewise. gas/ChangeLog: * testsuite/gas/riscv/zvksh.d: New test. * testsuite/gas/riscv/zvksh.s: New test. include/ChangeLog: * opcode/riscv-opc.h (MATCH_VSM3C_VI): New. (MASK_VSM3C_VI): New. (MATCH_VSM3ME_VV): New. (MASK_VSM3ME_VV): New. (DECLARE_INSN): New. * opcode/riscv.h (enum riscv_insn_class): Add instruction class support for Zvksh. opcodes/ChangeLog: * riscv-opc.c: Add Zvksh instructions.
