From 9c3044a210d69d475f76e4e269752e21ca4d3ac0 Mon Sep 17 00:00:00 2001 From: Claudiu Zissulescu Date: Tue, 3 Mar 2020 10:34:50 +0200 Subject: [PATCH] arc: Use accl_operand predicate for fma instructions. With the refurbish of ARC600' accumulator support, the mlo_operand doesn't reflect the proper low accumulator register for the newer ARCv2 accumulator register used by the fma instructions. Hence, replace it with accl_operand predicate. gcc/ xxxx-xx-xx Claudiu Zissulescu * config/arc/arc.md (fmasf4_fpu): Use accl_operand predicate. (fnmasf4_fpu): Likewise. --- gcc/ChangeLog | 5 +++++ gcc/config/arc/fpu.md | 4 ++-- 2 files changed, 7 insertions(+), 2 deletions(-) diff --git a/gcc/ChangeLog b/gcc/ChangeLog index 383aa381129..25e90e9b5f4 100644 --- a/gcc/ChangeLog +++ b/gcc/ChangeLog @@ -1,3 +1,8 @@ +2020-03-03 Claudiu Zissulescu + + * config/arc/arc.md (fmasf4_fpu): Use accl_operand predicate. + (fnmasf4_fpu): Likewise. + 2020-03-03 Claudiu Zissulescu * config/arc/arc.md (adddi3): Early expand the 64bit operation into diff --git a/gcc/config/arc/fpu.md b/gcc/config/arc/fpu.md index 6729795de54..14ebd865206 100644 --- a/gcc/config/arc/fpu.md +++ b/gcc/config/arc/fpu.md @@ -89,7 +89,7 @@ [(set (match_operand:SF 0 "register_operand" "=r,r,r,r,r") (fma:SF (match_operand:SF 1 "nonmemory_operand" "%0,r,0,r,F") (match_operand:SF 2 "nonmemory_operand" "r,r,F,F,r") - (match_operand:SF 3 "mlo_operand" "")))] + (match_operand:SF 3 "accl_operand" "")))] "TARGET_FP_SP_FUSED && (register_operand (operands[1], SFmode) || register_operand (operands[2], SFmode))" @@ -104,7 +104,7 @@ [(set (match_operand:SF 0 "register_operand" "=r,r,r,r,r") (fma:SF (neg:SF (match_operand:SF 1 "nonmemory_operand" "%0,r,0,r,F")) (match_operand:SF 2 "nonmemory_operand" "r,r,F,F,r") - (match_operand:SF 3 "mlo_operand" "")))] + (match_operand:SF 3 "accl_operand" "")))] "TARGET_FP_SP_FUSED && (register_operand (operands[1], SFmode) || register_operand (operands[2], SFmode))" -- 2.30.2
