From 361ca5c927eae645069e73cebc9840c5ee8d5a5f Mon Sep 17 00:00:00 2001 From: Jim Laskey Date: Wed, 17 Aug 2005 00:41:40 +0000 Subject: [PATCH] Remove ISel code generation for UINT_TO_FP and SINT_TO_FP. Now asserts if marked as legal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22816 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/PowerPC/PPCISelPattern.cpp | 36 ++------------------------- 1 file changed, 2 insertions(+), 34 deletions(-) diff --git a/lib/Target/PowerPC/PPCISelPattern.cpp b/lib/Target/PowerPC/PPCISelPattern.cpp index ccc4e08f0f1..d2b4ad421ed 100644 --- a/lib/Target/PowerPC/PPCISelPattern.cpp +++ b/lib/Target/PowerPC/PPCISelPattern.cpp @@ -1816,42 +1816,10 @@ unsigned ISel::SelectExpr(SDOperand N, bool Recording) { return Result; case ISD::UINT_TO_FP: - case ISD::SINT_TO_FP: { - assert (N.getOperand(0).getValueType() == MVT::i32 - && "int to float must operate on i32"); - bool IsUnsigned = (ISD::UINT_TO_FP == opcode); - Tmp1 = SelectExpr(N.getOperand(0)); // Get the operand register - Tmp2 = MakeFPReg(); // temp reg to load the integer value into - Tmp3 = MakeIntReg(); // temp reg to hold the conversion constant - - int FrameIdx = BB->getParent()->getFrameInfo()->CreateStackObject(8, 8); - MachineConstantPool *CP = BB->getParent()->getConstantPool(); - Opc = DestType == MVT::f64 ?
