From b5da8a4ae1fbd8e4ffab06cfeb5b32a94d0381bb Mon Sep 17 00:00:00 2001 From: Chandler Carruth Date: Mon, 21 Jan 2013 12:05:16 +0000 Subject: [PATCH] Move the inline cost analysis's primary cost query to TTI instead of the old CodeMetrics system. TTI has the specific advantage of being extensible and customizable by targets to reflect target-specific cost metrics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173032 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Analysis/InlineCost.cpp | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/lib/Analysis/InlineCost.cpp b/lib/Analysis/InlineCost.cpp index 5c4e7026d1e..cd211c408d6 100644 --- a/lib/Analysis/InlineCost.cpp +++ b/lib/Analysis/InlineCost.cpp @@ -422,7 +422,7 @@ bool CallAnalyzer::visitPtrToInt(PtrToIntInst &I) { if (lookupSROAArgAndCost(I.getOperand(0), SROAArg, CostIt)) SROAArgValues[&I] = SROAArg; - return isInstructionFree(&I, TD); + return TargetTransformInfo::TCC_Free == TTI.getUserCost(&I); } bool CallAnalyzer::visitIntToPtr(IntToPtrInst &I) { @@ -452,7 +452,7 @@ bool CallAnalyzer::visitIntToPtr(IntToPtrInst &I) { if (lookupSROAArgAndCost(Op, SROAArg, CostIt)) SROAArgValues[&I] = SROAArg; - return isInstructionFree(&I, TD); + return TargetTransformInfo::TCC_Free == TTI.getUserCost(&I); } bool CallAnalyzer::visitCastInst(CastInst &I) { @@ -469,7 +469,7 @@ bool CallAnalyzer::visitCastInst(CastInst &I) { // Disable SROA in the face of arbitrary casts we don't whitelist elsewhere. disableSROA(I.getOperand(0)); - return isInstructionFree(&I, TD); + return TargetTransformInfo::TCC_Free == TTI.getUserCost(&I); } bool CallAnalyzer::visitUnaryInstruction(UnaryInstruction &I) { @@ -782,7 +782,7 @@ bool CallAnalyzer::visitCallSite(CallSite CS) { bool CallAnalyzer::visitInstruction(Instruction &I) { // Some instructions are free.
