From 3da59db637a887474c1b1346c1f3ccf53b6c4663 Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Mon, 27 Nov 2006 01:05:10 +0000 Subject: For PR950: The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31931 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Utils/Local.cpp | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) (limited to 'lib/Transforms/Utils/Local.cpp') diff --git a/lib/Transforms/Utils/Local.cpp b/lib/Transforms/Utils/Local.cpp index 9a16bfccb3..366a95c49c 100644 --- a/lib/Transforms/Utils/Local.cpp +++ b/lib/Transforms/Utils/Local.cpp @@ -122,8 +122,19 @@ Constant *llvm::ConstantFoldInstOperands(unsigned Opc, const Type *DestTy, case Instruction::LShr: case Instruction::AShr: return ConstantExpr::get(Opc, Ops[0], Ops[1]); - case Instruction::Cast: - return ConstantExpr::getCast(Ops[0], DestTy); + case Instruction::Trunc: + case Instruction::ZExt: + case Instruction::SExt: + case Instruction::FPTrunc: + case Instruction::FPExt: + case Instruction::UIToFP: + case Instruction::SIToFP: + case Instruction::FPToUI: + case Instruction::FPToSI: + case Instruction::PtrToInt: + case Instruction::IntToPtr: + case Instruction::BitCast: + return ConstantExpr::getCast(Opc, Ops[0], DestTy); case Instruction::Select: return ConstantExpr::getSelect(Ops[0], Ops[1], Ops[2]); case Instruction::ExtractElement: -- cgit v1.2.3-18-g5258
