similar to: [LLVMdev] could you give me some advice ?

excuse me for bother you again . a little supplement Constant* c = findValue(m,"E1$entry"); Constant* c2 = findValue(m,"E1$str"); I can get string object from c2 string s = cast<ConstantArray>(c2)->getAsString(); but it is not applicable for c string s= cast<ConstantArray>(c)->getAsString(); // Assert Fail because c is ConstantExpr::GetElementPtr

for example , I have a LLVM bc file generated from c program like this ... char E1$str[3] = "E1"; char* E1$entry = (char*)E1$str; struct { char* name_list[16]; } table = { E1$entry, E2$entry, ... }; ... now I need load the bc file , get all names ("E1","E2"...) , then print and save it. of course, i only know the global variable table name . I can get

lizhuo,您好！ 不是很明白你的意思，好像你想从一个ConstantExpr::getPtrPtrFromArrayPtr 指针得到这个ConstantExpr 的内容， 但你的困难在哪里？ ======= 2006-03-25 22:04:14 您在来信中写道：======= >hi >I have one llvm program like this : >.. >; define ConstantArray >"E1$str" = internal constant [3 x sbyte] c"E1\00" > >; use getPtrPtrFromArrayPtr to define SByte* from ConstantArray

Hi, I got a problem when I am trying to insert a call function with pointer arguments. The function C proto-type is the following, void stat_func(char *); >ConstantArray *Cstr = dyn_cast<ConstantArray>(gI->getInitializer()); ...... >Function *exFunc = M->getOrInsertFunction("stat_func", Type::VoidTy, PointerType::get(Type::SByteTy),0); >std::vector<Value*>

Hello, I found saw some strange behavior (to me) when converting constant arrays to strings. Consider the following example: std::string Text = "HelloWorld"; unsigned TextLengthBefore = Text.length(); ConstantArray *pArray = dyn_cast<ConstantArray>(llvm::ConstantArray::get(pModule->getContext(), Text, true)); unsigned NumElements = pArray->getNumOperands(); Text =

Hi, I haven't seen a response and I'm curious if I should submit a patch for this.

Right now I am trying to capture the function name and the number of arguments , so this following is the pass I wrote . ------------------------------------------------------------- struct pass06a : public ModulePass { virtual bool runOnModule(Module &M) { std::vector<const Type*> pList; pList.push_back( PointerType::get(Type::SByteTy) ); pList.push_back(

Ok, I think I figured it out. I talked to someone, and we figured out that when I make a call to printf with a constant string, I need to make a global variable and use getElementPtr to reference it. The modified call for accessing the printf is: /* m is Module*, f is Function*, i is Instruction* */ Constant* constStr = ConstantArray::get("test\n"); GlobalVariable* gv =

I am writing a pass where I need to make a function deceleration for printf. Below is the code I'm trying to use. ----- bool MyPass::runOnModule(Module &m) { vector<const Type*> args; args.push_back(PointerType::get(Type::SByteTy)); Function* f = m.getOrInsertFunction("printf", FunctionType::get(Type::IntTy, args, true)); ----- When I insert a call

Given an object o of ElemType in an instance of EquivalenceClasses, I need to get a list of all members of the equivalence class that o is in. For various reasons, it is easiest if I could get an EquivalenceClasses::iterator that I can pass to member_begin and member_end. So naturally, I did something like this (pseudo-C++): EquivalenceClasses::iterator i = equiv.findValue(o);

Hello there I'm trying to compile llvm-gcc, but the compilation fails. This is due to the fact that the ConstantArray class does no longer have the getAsString method. It has been actually removed on Jan 31 (commit 6a89228faca4b30c4abc29b5dec98bdac011ea4c). Is there a patch for llvm-gcc which overcomes this problem? I've just svn-updated my working copy but it didn't change

Hello, I'm working on porting a project to LLVM 3.1. Unfortunately, my project makes very heavy use of ContantArray::getAsString() -- which was removed in LLVM 3.1. Is there an equivalent in 3.1? In other words, what is the best way to get the value of a string that was stored in a ConstantArray? Thanks, David -------------- next part -------------- An HTML attachment was scrubbed...

Hello everyone ! I followed http://stackoverflow.com/questions/4976298/modern-equivalent-of-llvm-annotationmanagerin order to get annotations from my target bytecode. All the examples that I give in the following is related to the code from that link. I have `__attribute__((annotate("DS"))) int f=0;` into the target C++ program and the related IR code: @.str = private unnamed_addr

Hi, Sorry for bothering you guys again. I got problem when I am trying to recover the Global Variable Initial value. What I did is like the following ConstantArray *Cstr = dyn_cast<ConstantArray>(gI->getInitializer()); // the above instruction enable me to get the content of initial string of global variable, like char a[10] ="test global"; And then I make some change for

Hi, In llvm 3.0 llvm::ConstantArray had a ::getAsCString() method that returned the buffer as a std::string. Now it seems that 3.1 this method dissapeared. I found that llvm::ConstantDataArray has a method called getAsString(), but it returns a Constant*. What is the safe way to retrieve the pointer of the Constant array as a C string?

HI , I understand that the standard C library functions are executed using the native library of the host machine. ( for example when we execute a bytecode to extract the profile info ) Is it possible to extract for each standard library function that is executed , the arguments that the function is called with. For example if printf ("%d", some_int ) when called during runtime

This question is similar to Ryan Lefever's post on May 1, 2006 about printf declaration. In my case, I want to insert fprintf(stderr, ...) calls. I'm new to LLVM, and I don't know what's the recipe for putting together the arguments. Can someone give me basic instructions or point me in the direction on what to do? I can't find any more documentation on this. Thanks!

Hey Duncan, Thanks! I figured out this piece of code finally: Value *gep = call->getArgOperand(0); if ( ConstantExpr *pCE = dyn_cast<ConstantExpr>(gep) ) { Value *firstop = pCE->getOperand(0); if (GlobalVariable *GV = dyn_cast<GlobalVariable>(firstop)){ Constant *v = GV->getInitializer(); if

How is this done? Everything logical I have tried has failed, here was one attempt: Constant *C = (Constant*) ConstantArray::get(inst2string(I)); //fucnction defined elsewhere //generates a correct Global string GlobalVariable *str = new GlobalVariable(C->getType(), true, GlobalValue::InternalLinkage, C, mkStrName( strNumber++ ), &M); std::vector<Value*>
