From 7553c341354c7790cebda40ea0d647f9d204544b Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Tue, 6 Mar 2007 03:41:50 +0000 Subject: Fix a bug in IntToPtr. Truncating to 64-bits only works if the integer is larger. Adjust so that it truncates to pointer width, only if necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34954 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/ExecutionEngine/Interpreter/Execution.cpp | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'lib/ExecutionEngine/Interpreter/Execution.cpp') diff --git a/lib/ExecutionEngine/Interpreter/Execution.cpp b/lib/ExecutionEngine/Interpreter/Execution.cpp index 76104b9..4a0c589 100644 --- a/lib/ExecutionEngine/Interpreter/Execution.cpp +++ b/lib/ExecutionEngine/Interpreter/Execution.cpp @@ -1058,7 +1058,11 @@ GenericValue Interpreter::executeIntToPtrInst(Value *SrcVal, const Type *DstTy, GenericValue Dest, Src = getOperandValue(SrcVal, SF); assert(isa(DstTy) && "Invalid PtrToInt instruction"); - Dest.PointerVal = (PointerTy) Src.IntVal.trunc(64).getZExtValue(); + uint32_t PtrSize = TD.getPointerSize(); + if (PtrSize != Src.IntVal.getBitWidth()) + Src.IntVal = Src.IntVal.trunc(PtrSize); + + Dest.PointerVal = (PointerTy) Src.IntVal.getZExtValue(); return Dest; } -- cgit v1.1
