similar to: [LLVMdev] LLVM AllocaInst and StoreInst

Dear All I'm trying to create storeInst using StoreInst *SI = new StoreInst(val, AI, BB); AI is an alloca instruction previously created, BB is the basicBlock I want to put instructionsi in. Val is the value to store. I've created val from a genericValue like this: Value* val = ConstantInt::get(getGlobalContext(), Result.IntVal); Result is the genericValue However I keep getting

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

Hello everybody, my problem is, that I want to get an array of pointers to all local variables in a function. This array will be used for transfering these Variables to another execution engine. I've code which generates this array, and a pointer to the target field of the array. name = variables.fname + "_pointerArray"; Instruction* pointerArray = new

Hi all, Would it be correct to say that the only instructions in LLVM IR that modify/access memory potentially are the following: (1) LoadInst : Ref (2) StoreInst : Mod (3) VAArgInst : Ref (?) (4) AllocaInst : Mod (5) MallocInst : Mod (6) FreeInst : Mod (7) CallInst : Mod/Ref ? Also, my earlier impression was that the GEP instruction only computes the effective address and does not

Hi, For some reason I'm finding that my table caption is disappearing if I print xtable output with the floating argument set to FALSE. Below is a very simple Sweave file that produces two tables the first has no caption and the second has a caption (if you want to see it http://www.zevross.com/temp/test.pdf). Does anyone know what I can do to fix this? Zev (I'm using Windows 7, 64

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

Hello, I am attempting to use llvm casting and intrinsic functions to do basic operations on Value pointers. I have read the online documentation and relevant portions of the source code and wrote the following code to do a Float to Double cast and then a log operation- Value *castFP(Value *i, Type *ty) const { return b->CreateFPCast(i, ty, n); } \\b is an IRBuilder and TheModule is an

Hello all, I set: InitRoots = true; in my gc plugin as i want the roots to be initialized to the "null" value. Is there a way to define which value should be the initial one? For example, i would like to initialize my roots to -5 (tagged, null value for the GC in my runtime system) instead of 0. Ofcourse, i could do it in the frontend (storing -5 to all GC roots), but i was wondering

Hi, I am trying to write a RMySQL sql script inside R such that part of the SQL would be R list or vector. For example, I want to select * from Atable where ID would equal to a members of R list or vector of "1, 2, 3". Here the ID list was generated inside R and then try to feed to mysql to call to get additional data sets. Can someone on the list help? Thanks. -- Waverley @ Palo

Hi All, we have an issue with our LLVM-based JIT compiler - executing the compiled code corrupts memory (and subsequently crashes) if we alloca more than 4k of variables (more than 511 8-byte ints). The same code works on Windows 7 (32 and 64 bit), Linux, MacOS. We compile LLVM and our program with Microsoft's Visual Studio 2010. Both debug and release builds are affected. The variables

Hi, I want to access an array in my instrumentation code. For example: GlobalVariable: int *counter; //counter the number of load/store operations in run-time int *counterArray; //record the load/store addresses //increase the counter if a load/store is performed std::vector<Constant *>index(2); index[0] = Constant::getNullvalue(Type:getInt32Ty(Context)); index[1] =

Good evening guys, I''m using now with 3 rails web app themes rails to generate the layouts, almosteverything working ok, only the names I write code in such a ride when I put atable in the header with character "ç" character shows the strange but data thatcomes from the database shows normal, which can be and how can I fix? Thank you all ... -- Alcelyo R Mariz Bacharel em

I don't think it's the same problem as you described. By printing I meant calling printf function and passing my global variable as one of the arguments. My code: Instruction* InstructionVisitor::incrementGlobalKey(Instruction* I) { IRBuilder<> Builder(I->getContext()); Builder.SetInsertPoint(I->getNextNode()); GlobalVariable* key =

Hello, I am receiving this error: assert(Slot != -1 && "Value in symtab but has no slot number!!"); While trying to generate a module at run time using LLVM classes. Specifically with an instance of StoreInst class. After I generate all the instructions, I try to save the Module to bytecode, but I receive that error in the method 'outputSymbolTable' Does anyone

Hi Tan Guangming, > I want to access an array in my instrumentation code. For example: > > GlobalVariable: > int *counter; //counter the number of load/store operations in run-time > int *counterArray; //record the load/store addresses strictly speaking these are not arrays, they are pointers. Also, you have written them in some kind of C-style idiom. What are the declarations
