From 977a76fbb6ea1b87dfd7fbbe2ae2afb63e982ff3 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Wed, 13 Feb 2008 22:28:48 +0000 Subject: Simplify some logic in ComputeMaskedBits. And change ComputeMaskedBits to pass the mask APInt by value, not by reference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47096 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/ARM/ARMISelLowering.cpp | 2 +- lib/Target/ARM/ARMISelLowering.h | 2 +- lib/Target/CellSPU/SPUISelLowering.cpp | 2 +- lib/Target/CellSPU/SPUISelLowering.h | 2 +- lib/Target/PowerPC/PPCISelLowering.cpp | 2 +- lib/Target/PowerPC/PPCISelLowering.h | 2 +- lib/Target/Sparc/SparcISelDAGToDAG.cpp | 4 ++-- lib/Target/X86/X86ISelLowering.cpp | 2 +- lib/Target/X86/X86ISelLowering.h | 2 +- 9 files changed, 10 insertions(+), 10 deletions(-) (limited to 'lib/Target') diff --git a/lib/Target/ARM/ARMISelLowering.cpp b/lib/Target/ARM/ARMISelLowering.cpp index a6c669dc88..a4ab393812 100644 --- a/lib/Target/ARM/ARMISelLowering.cpp +++ b/lib/Target/ARM/ARMISelLowering.cpp @@ -1762,7 +1762,7 @@ bool ARMTargetLowering::getPostIndexedAddressParts(SDNode *N, SDNode *Op, } void ARMTargetLowering::computeMaskedBitsForTargetNode(const SDOperand Op, - APInt Mask, + const APInt &Mask, APInt &KnownZero, APInt &KnownOne, const SelectionDAG &DAG, diff --git a/lib/Target/ARM/ARMISelLowering.h b/lib/Target/ARM/ARMISelLowering.h index 80ee51a164..285a20d23f 100644 --- a/lib/Target/ARM/ARMISelLowering.h +++ b/lib/Target/ARM/ARMISelLowering.h @@ -106,7 +106,7 @@ namespace llvm { SelectionDAG &DAG); virtual void computeMaskedBitsForTargetNode(const SDOperand Op, - APInt Mask, + const APInt &Mask, APInt &KnownZero, APInt &KnownOne, const SelectionDAG &DAG, diff --git a/lib/Target/CellSPU/SPUISelLowering.cpp b/lib/Target/CellSPU/SPUISelLowering.cpp index 6fe6e48bc8..f6e33599c6 100644 --- a/lib/Target/CellSPU/SPUISelLowering.cpp +++ b/lib/Target/CellSPU/SPUISelLowering.cpp @@ -2668,7 +2668,7 @@ SPUTargetLowering::getRegForInlineAsmConstraint(const std::string &Constraint, void SPUTargetLowering::computeMaskedBitsForTargetNode(const SDOperand Op, - APInt Mask, + const APInt &Mask, APInt &KnownZero, APInt &KnownOne, const SelectionDAG &DAG, diff --git a/lib/Target/CellSPU/SPUISelLowering.h b/lib/Target/CellSPU/SPUISelLowering.h index 3abb9d17fa..29242df71b 100644 --- a/lib/Target/CellSPU/SPUISelLowering.h +++ b/lib/Target/CellSPU/SPUISelLowering.h @@ -108,7 +108,7 @@ namespace llvm { virtual SDOperand PerformDAGCombine(SDNode *N, DAGCombinerInfo &DCI) const; virtual void computeMaskedBitsForTargetNode(const SDOperand Op, - APInt Mask, + const APInt &Mask, APInt &KnownZero, APInt &KnownOne, const SelectionDAG &DAG, diff --git a/lib/Target/PowerPC/PPCISelLowering.cpp b/lib/Target/PowerPC/PPCISelLowering.cpp index 6c4468c359..53be370f0a 100644 --- a/lib/Target/PowerPC/PPCISelLowering.cpp +++ b/lib/Target/PowerPC/PPCISelLowering.cpp @@ -3451,7 +3451,7 @@ SDOperand PPCTargetLowering::PerformDAGCombine(SDNode *N, //===----------------------------------------------------------------------===// void PPCTargetLowering::computeMaskedBitsForTargetNode(const SDOperand Op, - APInt Mask, + const APInt &Mask, APInt &KnownZero, APInt &KnownOne, const SelectionDAG &DAG, diff --git a/lib/Target/PowerPC/PPCISelLowering.h b/lib/Target/PowerPC/PPCISelLowering.h index 2b20e26c16..3843998b50 100644 --- a/lib/Target/PowerPC/PPCISelLowering.h +++ b/lib/Target/PowerPC/PPCISelLowering.h @@ -254,7 +254,7 @@ namespace llvm { virtual SDOperand PerformDAGCombine(SDNode *N, DAGCombinerInfo &DCI) const; virtual void computeMaskedBitsForTargetNode(const SDOperand Op, - APInt Mask, + const APInt &Mask, APInt &KnownZero, APInt &KnownOne, const SelectionDAG &DAG, diff --git a/lib/Target/Sparc/SparcISelDAGToDAG.cpp b/lib/Target/Sparc/SparcISelDAGToDAG.cpp index 81e15397c7..29fe6a4160 100644 --- a/lib/Target/Sparc/SparcISelDAGToDAG.cpp +++ b/lib/Target/Sparc/SparcISelDAGToDAG.cpp @@ -110,7 +110,7 @@ namespace { /// in Mask are known to be either zero or one and return them in the /// KnownZero/KnownOne bitsets. virtual void computeMaskedBitsForTargetNode(const SDOperand Op, - APInt Mask, + const APInt &Mask, APInt &KnownZero, APInt &KnownOne, const SelectionDAG &DAG, @@ -270,7 +270,7 @@ const char *SparcTargetLowering::getTargetNodeName(unsigned Opcode) const { /// be zero.
