similar to: [LLVMdev] Extraction of constant operands from the instruction

Hi all, I am trying to extract the operands from an instruction, for that i am iterating over the operand list as defined by the user class. for (User::op_iterator O = i->op_begin() ;O != i->op_end(); ++O) { Value *v = *O; llvm::cout << v->getNameStr() ; } However, whenever there is a constant operand like a numerical value, it does not displays any value at all, i checked

Hi, I'm gonna try to give some feedback, but I have only been working with LLVM for a few days, so don't take what I'm saying without verifying :-) > BasicBlock *ProgSlicer::CloneBasicBlock(const BasicBlock *BB, > DenseMap<const Value*, Value*> &ValueMap, > const char *NameSuffix, Function *F) { > > BasicBlock

Hi all, I am trying to write a pass where i am creating a clone of a function (the only difference being, the new function returns void , instead of any value). I am creating a new Function Type with a void return type (rest being the same as original function), and using this i am creating a new function body. Then, i clone the body of the old function into new function, but when ever i

Tobias, I've attached an updated copy of the patch. I believe that I accounted for all of your suggestions except for: 1. You said that I could make AA a member of the class and initialize it for each basic block. I suppose that I'd need to make it a pointer, but more generally, what is the thread-safely model that I should have in mind for the analysis passes (will multiple threads

Hi all, I am a newbie in LLVM and I am trying to replace the function like: old function || new function ======================================= int haha(int a) { int haha(int a, char* ID) { ===> } } Of course in the newly replaced function "int haha(int,

Hi all, I just start to learn llvm. I am trying to get the operand's name of some instruction that invokes a function field of a struct. While, I found in the result that there is a sequence number attached to the function field name. Below is an example: /******source code t2.c*******/ #include <stdio.h> void F(){printf("F\n");} void E(){printf("E\n");} void

Hello All, I am creating a Module and getting Function pointer as below in some function. Function *fn = module->getFunction(fnName); printf("func Name: %s.\n", fn->getName().str().c_str()); . . return (intptr_t) fn; This prints : "func Name: main." I convert the ptr to int and return it. Later I am receiving this as a Func Handler in other function

Hi, I am trying to extract the name of the variables passed as an Argument to a Function. I am using a runOnFunction Pass. For example in the following IR respresentation, define void @foo(i32 %limit) { entry: -- -- } I should be able to walk the IR and get '%limit' as the external variable passed to the function. Another question, Is it possible to create a basic symbol table (

HI all, here is a llvm IR : invoke void @__cxa_throw(i8* %7, i8* bitcast (%struct.__fundamental_type_info_pseudo* @_ZTIi to i8*), void (i8*)* null) noreturn to label %invcont unwind label %lpad say I want to get the Invoke's Operand's name, I use getOperand(i)->getName(), it can work for that the Operand hasname, but some Operand hasn't name, So, My problem is how

Hello, I have a couple of doubts, as listed below: 1. To list all the global variables in the module, I am iterating using type_iterator and for each Type I get, I am using value_iterator to iterate over Values . In the second iteration I am getting unexpected results. For each type obtained from type_iterator->second, value_iterator->first produces the same list as what

Hello, I am a newbie to LLVM and right now I am on the hook to parse some IR code and do some instrumentations. However, my problem is that no matter how I tweak my parsing code, it simply cannot print out anything. So here is my C code: int your_fun(int arg2) { int x = arg2; return x+2; } And here is my parsing code: #include <llvm/IR/Module.h> #include

If I have an operand as a Value from an instruction like: Value* V = opnd->get(); and I am sure this is a variable, I want to know the variable name (in source code) for this Value object. I am doing it like this: const Function* Func; if (const Argument* Arg = dyn_cast<Argument>(V)) { Func =

if (ConstantInt *c = (ConstantInt *) dyn_cast<ConstantInt>(index)){ errs() << "And it's a constant!!!!!!1111oneone!!

Sir, I am using the op_begin and op_end iterator for iterating over the operands as mentioned below. for (User::op_iterator operand=j->op_begin(),operand_end=j->op_end();operand!=operand_end;++operand){ Value *v=operand->get(); const Type *t=v->getType(); cerr<<endl<<" operand: "<<"[ "<<v->hasName()<<"

Hi, all I try to get the Instructions where one function use the global variable. for (llvm::Module::global_iterator gvar_iter = M.global_begin(); gvar_iter != M.global_end(); gvar_iter++) { llvm::GlobalVariable *gvar = &*gvar_iter; llvm::errs() << "const global var: " << gvar->getName() << "\n"; for (

Hi, all I want to know how a llvm pass output constant char array defined from the input source. Here's an example that I want to do. == test input source == char* msg = "hello, world\n"; void msg_out(char * in) { printf("msg: %s \n", in); } main () { ... msg_out(msg); ... } == llvm pass snippet == ... const CallInst* ci =

Closing this, found below links to get variable name.   http://groups.google.com/group/llvm-dev/browse_thread/thread/1a239f0d24db2b5c   http://markmail.org/message/fj5qg44vyjsdde7k#query:+page:1+mid:5zhmyncisenomcga+state:results           I could do following, to get the required information.                 const CallInst *CI = dyn_cast<CallInst>(Insn);                 int numoperands =
