From bdb91009cf250fb22c21ae7f5072263492f2b08c Mon Sep 17 00:00:00 2001 From: Richard Sandiford <richard.sandiford@arm.com> Date: Thu, 29 Sep 2022 11:32:56 +0100 Subject: [PATCH 023/157] [Backport][SME] aarch64: Make more use of aarch64_feature_flags Reference: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=fed55a60e5b230bc159617f26e33611073c672fd A previous patch added a aarch64_feature_flags typedef, to abstract the representation of the feature flags. This patch makes existing code use the typedef too. Hope I've caught them all! gcc/ * common/config/aarch64/aarch64-common.cc: Use aarch64_feature_flags for feature flags throughout. * config/aarch64/aarch64-protos.h: Likewise. * config/aarch64/aarch64-sve-builtins.h: Likewise. * config/aarch64/aarch64-sve-builtins.cc: Likewise. * config/aarch64/aarch64.cc: Likewise. * config/aarch64/aarch64.opt: Likewise. * config/aarch64/driver-aarch64.cc: Likewise. --- gcc/common/config/aarch64/aarch64-common.cc | 19 +++++++------- gcc/config/aarch64/aarch64-protos.h | 5 ++-- gcc/config/aarch64/aarch64-sve-builtins.cc | 29 ++++++++++++--------- gcc/config/aarch64/aarch64-sve-builtins.h | 9 ++++--- gcc/config/aarch64/aarch64.cc | 29 +++++++++++---------- gcc/config/aarch64/aarch64.opt | 2 +- gcc/config/aarch64/driver-aarch64.cc | 10 +++---- 7 files changed, 56 insertions(+), 47 deletions(-) diff --git a/gcc/common/config/aarch64/aarch64-common.cc b/gcc/common/config/aarch64/aarch64-common.cc index ac3486d71..3efa57b26 100644 --- a/gcc/common/config/aarch64/aarch64-common.cc +++ b/gcc/common/config/aarch64/aarch64-common.cc @@ -204,9 +204,9 @@ aarch64_handle_option (struct gcc_options *opts, struct aarch64_option_extension { const char *name;
