similar to: [LLVMdev] AllocaInst remapped as NULL in llvm::MapValue

Hi, For the following code const Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type, 0, "flag", Bb); Bb->getInstList().push_back(newInst); It gives me the error " error: no matching constructor for initialization of 'llvm::AllocaInst' AllocaInst* newInst = new

Hi, I'm trying to get my head around c++ - IR - c++ API and getting used tramform manual information to code. The manual states alloca is defined for <type>. FunstionType is a type, so alloca for functionType should be possible? Not? If we have a valid Module *m we can get an allocate instruction allocating space for a non-argumented function as follows: AllocaInst* pa2 = new

Just a note: I just checked in a change that corrects some very non-intuitive behavior of the AllocaInst & MallocInst classes. Before, the constructor would take a Type which would specify the return type of the instruction, instead of the operand type. Now it takes the operand type directly. More concretely: LLVM Code: X = alloca int ; int* Y = malloc int * ; int** Old C++

You should be able to use the second alternative that Nick proposed: cast<PointerType*>(pointer_value->getType())->getElementType() Reid On Fri, May 28, 2010 at 9:37 AM, Curtis Faith <curtis at curtisfaith.com> wrote: > Thanks Nick, > Unfortunately, that is indeed what I asked for but not what I really am > looking for. > My naive approach is to store symbol table

Hi, I'm trying to replace pointer typed alloca instructions to allocate a vector of pointers. The idea is to change from [1] to [2]: [1]: %0 = alloca i<N>* [2]: %0 = alloca <3 x i8*> I did it this way: - first, create and insert [2] (for debug purpose, not necessary to insert) - mutate type so that replaceAllUsesWith can be called in a correctly typed way - replace all

Is there a recommended way to retrieve the original type from an AllocaInst object? For example, I am creating alloca instructions using the IRBuilder interface like: alloca = builder.CreateAlloca( Type::getDoubleTy( context ), 0, variableName.c_str() ); and I place the alloca into a symbol table. Later when I am generating instructions for an assignment operation, I want to check the type of

Thanks Nick, Unfortunately, that is indeed what I asked for but not what I really am looking for. My naive approach is to store symbol table entries as Value* objects so I can allocate global variables and alloca variables and place them into the symbol table and the rest of the code didn't need to know which kind they were, in general. Loads and Stores of these types (as well as other

I remember reading in a previous thread by Chris that all instructions will have the "instruction to insert before" as an argument to their constructors. In the code I have, this hasn't been done for the AllocaInst. I did a recent "cvsupdate", but the code still hadn't changed. Has this code already been updated ? If not, I request that it be updated as soon as

Hello, I have the following problem: I need to allocate an array. I know it's size - it's constant (ConstExpr), but my problem is that I know it only during the runtime (i.e for every variable I'm trying to allocate an array equal to size of a variable). As I understand I can't do it, since it's possible to initialize ArrayType only if I know it's size in integer units.

The plan is to update the CSIL CVS tree soon. When that happens you should get

Hello, Hopefully this is the correct place for this sort of question. I have been trying to do some simple instrumentation of LLVM IR, and I have been confused by the return type of alloca. When passing an AllocaInst as a parameter to a function call, the parameter type is i32**, which is not what I would expect. Really I would like the address of the allocated memory. What am I missing? And is

Hi. I don't know if this a bug or just annoying to me: > x <- c(1,2,3,NA) > table(x, exclude=NULL) x 1 2 3 <NA> 1 1 1 1 > table(factor(x), exclude=NULL) 1 2 3 1 1 1 I don't think many people use factor(x, exclude=NULL): it is not the default handling of character data by read.table().

Hello All, I am having a problem with using CloneFunctionInto to clone a function that includes changing the type of a value using the VMap. Specifically, I am using the VMap to change the address space of values that have particular pointer types. The problem seems to be that RemapInstruction successfully changes the operands using the VMap, but the VTy member indicating the type of the

Hi, I am trying to write a simple interpreter. I am trying to generate LLVM IR for assignment operation. The code for the generation part looks like this llvm::Value* codeGenSymTab(llvm::LLVMContext& context) { > printf("\n CodeGen SymTab \n"); > Value *num = ConstantInt::get(Type::getInt64Ty(context), aTable.value, > true); > Value *alloc = new

Hi there, I am wondering how I can prevent the LLVM from re-ordering the added local variables during instrumentation? Because, during the instrumentation, I add some metadata to some local variables, exactly next to it, and the generated bitcode looks good. However, when it is executed, basically the stack is formed as all original local variables are located next to each other, and then all the

Hi I am having the most basic of problems. I have setup a PDC with samba 2.2.2 and am trying to get my Win200) machine to join the domain.
