From 82e9597c9ec1c14a402d47f2d9b544235998be1e Mon Sep 17 00:00:00 2001 From: Matthew Malcomson Date: Mon, 13 Jan 2020 15:31:39 +0000 Subject: [PATCH] [gas][aarch64] Turn on SVE when using f32mm or f64mm extensions There are no instructions under these matrix multiply extensions that can be used without having SVE enabled. Since these extensions require SVE, we make that explicit in the options table. Tested on aarch64-none-elf without regressions. gas/ChangeLog: 2020-01-13 Matthew Malcomson * config/tc-aarch64.c (f64mm, f32mm): Add sve as a feature dependency. --- gas/ChangeLog | 5 +++++ gas/config/tc-aarch64.c | 4 ++-- 2 files changed, 7 insertions(+), 2 deletions(-) diff --git a/gas/ChangeLog b/gas/ChangeLog index 0bf722b209..184af58abc 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,8 @@ +2020-01-13 Matthew Malcomson + + * config/tc-aarch64.c (f64mm, f32mm): Add sve as a feature + dependency. + 2020-01-13 Claudiu Zissulescu * config/tc-arc.c (arc_select_cpu): Re-init the bfd if we change diff --git a/gas/config/tc-aarch64.c b/gas/config/tc-aarch64.c index 8fa8657afc..4f9c6030c5 100644 --- a/gas/config/tc-aarch64.c +++ b/gas/config/tc-aarch64.c @@ -9063,9 +9063,9 @@ static const struct aarch64_option_cpu_value_table aarch64_features[] = { {"i8mm", AARCH64_FEATURE (AARCH64_FEATURE_I8MM, 0), AARCH64_ARCH_NONE}, {"f32mm", AARCH64_FEATURE (AARCH64_FEATURE_F32MM, 0), - AARCH64_ARCH_NONE}, + AARCH64_FEATURE (AARCH64_FEATURE_SVE, 0)}, {"f64mm", AARCH64_FEATURE (AARCH64_FEATURE_F64MM, 0), - AARCH64_ARCH_NONE}, + AARCH64_FEATURE (AARCH64_FEATURE_SVE, 0)}, {NULL, AARCH64_ARCH_NONE, AARCH64_ARCH_NONE}, };
