From 8ed77a2356c3562f96c64f968e7529065c128c6a Mon Sep 17 00:00:00 2001 From: Alex Coplan <alex.coplan@arm.com> Date: Wed, 10 Jan 2024 14:50:49 +0000 Subject: [PATCH] aarch64: Make ldp/stp pass off by default As discussed on IRC, this makes the aarch64 ldp/stp pass off by default. This should stabilize the trunk and give some time to address the P1 regressions. gcc/ChangeLog: * config/aarch64/aarch64.opt (-mearly-ldp-fusion): Set default to 0. (-mlate-ldp-fusion): Likewise. --- gcc/config/aarch64/aarch64.opt | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/gcc/config/aarch64/aarch64.opt b/gcc/config/aarch64/aarch64.opt index ceed5cdb201f..c495cb34fbfb 100644 --- a/gcc/config/aarch64/aarch64.opt +++ b/gcc/config/aarch64/aarch64.opt @@ -290,12 +290,12 @@ Target Var(aarch64_track_speculation) Generate code to track when the CPU might be speculating incorrectly. mearly-ldp-fusion -Target Var(flag_aarch64_early_ldp_fusion) Optimization Init(1) +Target Var(flag_aarch64_early_ldp_fusion) Optimization Init(0) Enable the copy of the AArch64 load/store pair fusion pass that runs before register allocation. mlate-ldp-fusion -Target Var(flag_aarch64_late_ldp_fusion) Optimization Init(1) +Target Var(flag_aarch64_late_ldp_fusion) Optimization Init(0) Enable the copy of the AArch64 load/store pair fusion pass that runs after register allocation. -- GitLab
