From f289749578d114b6fe71f62eaef05d63138d05e0 Mon Sep 17 00:00:00 2001 From: Alexander Monakov Date: Wed, 17 May 2023 21:35:54 +0300 Subject: [PATCH] tree-ssa-math-opts: correct -ffp-contract= check Since tree-ssa-math-opts may freely contract across statement boundaries we should enable it only for -ffp-contract=fast instead of disabling it for -ffp-contract=off. No functional change, since -ffp-contract=on is not exposed yet. gcc/ChangeLog: * tree-ssa-math-opts.cc (convert_mult_to_fma): Enable only for FP_CONTRACT_FAST (no functional change). --- gcc/tree-ssa-math-opts.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/gcc/tree-ssa-math-opts.cc b/gcc/tree-ssa-math-opts.cc index b58a2ac9e6a8..d71c51dc0ea2 100644 --- a/gcc/tree-ssa-math-opts.cc +++ b/gcc/tree-ssa-math-opts.cc @@ -3320,7 +3320,7 @@ convert_mult_to_fma (gimple *mul_stmt, tree op1, tree op2, imm_use_iterator imm_iter; if (FLOAT_TYPE_P (type) - && flag_fp_contract_mode == FP_CONTRACT_OFF) + && flag_fp_contract_mode != FP_CONTRACT_FAST) return false; /* We don't want to do bitfield reduction ops. */ -- 2.47.2
