From 0c37fef39fa0a8f77ea4fc67d1bbf5067d4bddb9 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christoph=20M=C3=BCllner?= Date: Fri, 8 Sep 2023 08:19:32 +0200 Subject: [PATCH] riscv: bitmanip: Remove duplicate zero_extendhi2 pattern MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We currently have two identical zero_extendhi2 patterns: * '*zero_extendhi2_zbb' * '*zero_extendhi2_bitmanip' This patch removes the *_zbb pattern and ensures that all sign- and zero-extensions use the postfix '_bitmanip'. Signed-off-by: Christoph Müllner gcc/ChangeLog: * config/riscv/bitmanip.md (*extend2_zbb): Rename postfix to _bitmanip. (*extend2_bitmanip): Renamed pattern. (*zero_extendhi2_zbb): Remove duplicated pattern. --- gcc/config/riscv/bitmanip.md | 13 +------------ 1 file changed, 1 insertion(+), 12 deletions(-) diff --git a/gcc/config/riscv/bitmanip.md b/gcc/config/riscv/bitmanip.md index 1544ef4e1252..431b32922135 100644 --- a/gcc/config/riscv/bitmanip.md +++ b/gcc/config/riscv/bitmanip.md @@ -283,7 +283,7 @@ [(set_attr "type" "bitmanip,load") (set_attr "mode" "")]) -(define_insn "*extend2_zbb" +(define_insn "*extend2_bitmanip" [(set (match_operand:SUPERQI 0 "register_operand" "=r,r") (sign_extend:SUPERQI (match_operand:SHORT 1 "nonimmediate_operand" " r,m")))] @@ -294,17 +294,6 @@ [(set_attr "type" "bitmanip,load") (set_attr "mode" "")]) -(define_insn "*zero_extendhi2_zbb" - [(set (match_operand:GPR 0 "register_operand" "=r,r") - (zero_extend:GPR - (match_operand:HI 1 "nonimmediate_operand" " r,m")))] - "TARGET_ZBB" - "@ - zext.h\t%0,%1 - lhu\t%0,%1" - [(set_attr "type" "bitmanip,load") - (set_attr "mode" "HI")]) - (define_expand "rotrdi3" [(set (match_operand:DI 0 "register_operand") (rotatert:DI (match_operand:DI 1 "register_operand") -- 2.47.2
