From e5e719d8854a6bca60aff1d87f5b5eb556f55695 Mon Sep 17 00:00:00 2001 From: Simon Pilgrim Date: Sat, 4 Apr 2020 11:42:06 +0100 Subject: [PATCH] [X86][SSE] lowerV8I16Shuffle - lower compaction shuffles using PACKUSDW(PBLENDW,PBLENDW) on SSE41+ Similar to the lowerV16I8Shuffle implementation, for binary compaction v8i16 shuffles we can avoid the PUNPCKLDQ(PSHUFB,PSHUFB) pattern on SSE41+ targets by using PACKUSDW and PBLENDW. Before SSE41 we would need to use PACKSSDW but that requires sign extension that seems to destroy any gains, even on targets without PSHUFB. This is a bigger gain on AMD than Intel targets but should never be a regression, and avoiding the shuffle mask load(s) is always useful. Noticed in codegen while dealing with PR31443. --- llvm/lib/Target/X86/X86ISelLowering.cpp | 23 +++ llvm/test/CodeGen/X86/cast-vsel.ll | 32 ++-- llvm/test/CodeGen/X86/masked_store_trunc.ll | 38 ++-- llvm/test/CodeGen/X86/masked_store_trunc_ssat.ll | 51 +++-- llvm/test/CodeGen/X86/masked_store_trunc_usat.ll | 63 +++---- llvm/test/CodeGen/X86/phaddsub.ll | 8 +- llvm/test/CodeGen/X86/psubus.ll | 24 +-- llvm/test/CodeGen/X86/shuffle-vs-trunc-256.ll | 231 ++++++++--------------- llvm/test/CodeGen/X86/shuffle-vs-trunc-512.ll | 67 +++---- llvm/test/CodeGen/X86/vector-reduce-and-bool.ll | 8 +- llvm/test/CodeGen/X86/vector-reduce-or-bool.ll | 8 +- llvm/test/CodeGen/X86/vector-reduce-xor-bool.ll | 8 +- llvm/test/CodeGen/X86/vector-shuffle-128-v8.ll | 92 +++++---- llvm/test/CodeGen/X86/vector-trunc-packus.ll | 160 ++++++---------- llvm/test/CodeGen/X86/vector-trunc-ssat.ll | 162 +++++++--------- llvm/test/CodeGen/X86/vector-trunc-usat.ll | 174 +++++++---------- llvm/test/CodeGen/X86/vector-trunc.ll | 141 ++++++-------- 17 files changed, 557 insertions(+), 733 deletions(-) diff --git a/llvm/lib/Target/X86/X86ISelLowering.cpp b/llvm/lib/Target/X86/X86ISelLowering.cpp index 57d27ed..e2df09e 100644 --- a/llvm/lib/Target/X86/X86ISelLowering.cpp +++ b/llvm/lib/Target/X86/X86ISelLowering.cpp @@ -14713,6 +14713,29 @@ static SDValue lowerV8I16Shuffle(const SDLoc &DL, ArrayRef Mask, Zeroable, Subtarget, DAG)) return V;
