From 6551c119bf788b6b9e3475e5bacf21d589ba9405 Mon Sep 17 00:00:00 2001 From: Tsukasa OI Date: Wed, 26 Jul 2023 01:39:44 +0000 Subject: [PATCH] RISC-V: Add actual 'Zvkt' extension support The 'Zvkt' extension is listed on the added extensions in the GNU Binutils version 2.41 (see binutils/NEWS). However, the support of this extension was actually missing. This commit adds actual support of this extension and adds implications from 'Zvkn' and 'Zvks' superset extensions. bfd/ChangeLog: * elfxx-riscv.c (riscv_implicit_subsets) Add implications from 'Zvkn' and 'Zvks'. (riscv_supported_std_z_ext): Add 'Zvkt' to the supported extension list. --- bfd/elfxx-riscv.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/bfd/elfxx-riscv.c b/bfd/elfxx-riscv.c index b43d2cfa0fa..ba5165766b2 100644 --- a/bfd/elfxx-riscv.c +++ b/bfd/elfxx-riscv.c @@ -1162,6 +1162,7 @@ static struct riscv_implicit_subset riscv_implicit_subsets[] = {"zvkn", "zvknha", check_implicit_always}, {"zvkn", "zvknhb", check_implicit_always}, {"zvkn", "zvbb", check_implicit_always}, + {"zvkn", "zvkt", check_implicit_always}, {"zvkng", "zvkn", check_implicit_always}, {"zvkng", "zvkg", check_implicit_always}, {"zvknc", "zvkn", check_implicit_always}, @@ -1169,6 +1170,7 @@ static struct riscv_implicit_subset riscv_implicit_subsets[] = {"zvks", "zvksed", check_implicit_always}, {"zvks", "zvksh", check_implicit_always}, {"zvks", "zvbb", check_implicit_always}, + {"zvks", "zvkt", check_implicit_always}, {"zvksg", "zvks", check_implicit_always}, {"zvksg", "zvkg", check_implicit_always}, {"zvksc", "zvks", check_implicit_always}, @@ -1296,6 +1298,7 @@ static struct riscv_supported_ext riscv_supported_std_z_ext[] = {"zvks", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, {"zvksg", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, {"zvksc", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, + {"zvkt", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, {"zvl32b", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, {"zvl64b", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, {"zvl128b", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, -- 2.30.2
