From 715a8bc8d471d9b8ed5361b32055ae2be6b75fb7 Mon Sep 17 00:00:00 2001 From: Uros Bizjak Date: Thu, 26 Nov 2020 15:18:26 +0100 Subject: [PATCH] i386: Cleanup argument handling in ix86_expand_*_builtin functions. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There is no need for struct with rtx and mode members since mode is never used. 2020-11-26 Uroš Bizjak gcc/ * config/i386/i386-expand.c (ix86_expand_multi_arg_builtin): Remove args array of structs, declare rtx xops array instead. Update all uses. (ix86_expand_args_builtin): Ditto. (ix86_expand_round_builtin): Ditto. (ix86_expand_special_args_builtin): Ditto. --- gcc/config/i386/i386-expand.c | 112 +++++++++++++++++------------------------- 1 file changed, 44 insertions(+), 68 deletions(-) diff --git a/gcc/config/i386/i386-expand.c b/gcc/config/i386/i386-expand.c index 4707ebff2..408cd9b 100644 --- a/gcc/config/i386/i386-expand.c +++ b/gcc/config/i386/i386-expand.c @@ -8299,16 +8299,12 @@ ix86_expand_multi_arg_builtin (enum insn_code icode, tree exp, rtx target, enum rtx_code sub_code) { rtx pat;
