From 255f20f7f76e4ca1ac1c73294852cb6fcb18c77d Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Thu, 1 Apr 2010 06:04:33 +0000 Subject: Fix sdisel memcpy, memset, memmove lowering: 1. Makes it possible to lower with floating point loads and stores. 2. Avoid unaligned loads / stores unless it's fast. 3. Fix some memcpy lowering logic bug related to when to optimize a load from constant string into a constant. 4. Adjust x86 memcpy lowering threshold to make it more sane. 5. Fix x86 target hook so it uses vector and floating point memory ops more effectively. rdar://7774704 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100090 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/PowerPC/PPCISelLowering.cpp | 4 ++-- lib/Target/PowerPC/PPCISelLowering.h | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) (limited to 'lib/Target/PowerPC') diff --git a/lib/Target/PowerPC/PPCISelLowering.cpp b/lib/Target/PowerPC/PPCISelLowering.cpp index 2c072c1..d00fbff 100644 --- a/lib/Target/PowerPC/PPCISelLowering.cpp +++ b/lib/Target/PowerPC/PPCISelLowering.cpp @@ -5539,8 +5539,8 @@ PPCTargetLowering::isOffsetFoldingLegal(const GlobalAddressSDNode *GA) const { return false; } -EVT PPCTargetLowering::getOptimalMemOpType(uint64_t Size, unsigned Align, - bool isSrcConst, bool isSrcStr, +EVT PPCTargetLowering::getOptimalMemOpType(uint64_t Size, + unsigned DstAlign, unsigned SrcAlign, SelectionDAG &DAG) const { if (this->PPCSubTarget.isPPC64()) { return MVT::i64; diff --git a/lib/Target/PowerPC/PPCISelLowering.h b/lib/Target/PowerPC/PPCISelLowering.h index 9c390ac..2d5daef 100644 --- a/lib/Target/PowerPC/PPCISelLowering.h +++ b/lib/Target/PowerPC/PPCISelLowering.h @@ -347,8 +347,8 @@ namespace llvm { virtual bool isOffsetFoldingLegal(const GlobalAddressSDNode *GA) const; - virtual EVT getOptimalMemOpType(uint64_t Size, unsigned Align, - bool isSrcConst, bool isSrcStr, + virtual EVT getOptimalMemOpType(uint64_t Size, + unsigned DstAlign, unsigned SrcAlign, SelectionDAG &DAG) const; /// getFunctionAlignment - Return the Log2 alignment of this function. -- cgit v1.1
