I am new to LLVM and couldn't find any llvm-user list, so I am posting my user question here, sorry. I am trying to create a simple "puts" call accepting the static string, with the code below. The last line (CallInst::Create) fails with an assert: "Calling a function with a bad signature!" Because the type of function is void(u8*) and the argument supplied is:

I am trying to create such module with API (it's equivalent to c++: const char* ss[] = {"s1","s2"};): @ss = global [2 x i8*] [i8* getelementptr inbounds ([3 x i8]* @.str1, i32 0, i32 0), i8* getelementptr inbounds ([3 x i8]* @.str2, i32 0, i32 0)] ; <[2 x i8*]*> [#uses=0] @.str1 = private constant [3 x i8] c"s1\00", align 1 ; <[3 x i8]*> [#uses=1]

Hi all. I would like to declare a function that takes a function pointer as an argument. In C, it would be : void execute(char (*func)(void*), void *param) So, in my compiler, I have : std::vector<const Type *> cbFPtrArgs(1, Type::getInt8PtrTy(C)); FunctionType * cbFPtrTy = FunctionType::get(Type::getInt8Ty(C), cbFPtrArgs, false); Function * func =

I am new to LLVM API. and I am experimenting with it. I want to create Global Variables in a module. I am able to create local variables using IRBuilder class. I tried using GlobalVariable class to create global variables. but it doesn't work. my code looks like this: Module* mod = new Module("test", getGlobalContext()); Constant* c = mod->getOrInsertFunction("main",

I got a little problems with strings (const char pointers). Global variables holding the string literal are declared correctly, but i have a problem when I pass this string to a function: it asserts with this message. Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"), function

Ok, now it's arising another problem. IR code that I obtain is the following: i8* bitcast ([5 x i8] c"hello\00" to i8*) generated from instructions: ConstantExpr::getBitCast (ConstantDataArray::getString (getGlobalContext (), "hello"), PointerType::get (Type::getInt8Ty (getGlobalContext ()), 0)) but the LLC tool says: invalid cast opcode for cast from '[5 x i8]'

Hi Victor, this code from the verifier broke the Ada front-end build: const Module* M = CI.getParent()->getParent()->getParent(); Constant *MallocFunc = M->getFunction("malloc"); if (CI.getOperand(0) == MallocFunc) { const PointerType *PTy = PointerType::getUnqual(Type::getInt8Ty(CI.getParent()->getContext())); Assert1(CI.getType() == PTy, "Malloc

I create a function with an empty signature: void llvm_start_new_function() { llvm::outs() << "Staring new LLVM function ...\n"; Mod = new llvm::Module("module", llvm::getGlobalContext()); builder = new llvm::IRBuilder<>(llvm::getGlobalContext()); llvm::FunctionType *funcType = llvm::FunctionType::get(builder->getVoidTy(), false);

I'm encountering a few problems in my migration that I haven't yet figured out. `getOrInsertFunction` is generating a SEGFAULT at FunctionType::isValidArgumentType(llvm::Type*).  I'm calling it as:     generic_ptr_ = llvm::PointerType::get( llvm::Type::getInt8Ty(context), 0 );     f_natural_int = llvm::IntegerType::get(context, 64);     module->getOrInsertFunction(        

You need a pointer-to-function type, but FunctionType just gives you a function type. Use PointerType::getUnqual(FunctionType::get(...)). Or TypeBuilder<char (*func)(void*), false>::get(context) from Support/TypeBuilder.h.

Evening, I was writing some code that tried to insert calls to the llvm.annotation intrinsic function, which has a signature of (i32, i8*, i8*, i32). The code is below. void addAnnotation( BasicBlock *block, Function *F) { string foo = "foo"; string bar = "barr"; Type *charTy = Type::getInt8Ty(block->getContext()); ArrayType *s1Ty =

I am trying to get a handle on IR builder, at least some basics. I ran through a tutorial here: Create a working compiler with the LLVM framework, Part 1 <http://www.ibm.com/developerworks/library/os-createcompilerllvm1/>, and it worked well enough. I have some simple code that creates a hello world IR. I am trying to now bring in some concepts from the Kaleidoscope tutorial, namely

Hello; Thanks to Eli for the pointer to the ConstantDataArray::getString() fucntion. Now I am trying to declare a global char array with the content "hi" and call a function "print" (which takes a char pointer and return an insteger. I am doing the following in the code - Function Creation: PointerType* array = PointerType::get(IntegerType::getInt8Ty(getGlobalContext())

Hi,everyone. I'm writing a pass in which a CallInst to an external function will be inserted. The function is declared like this: void func(int a, unsigned chat *p); and in the Pass(a Function Pass ,and using the InstVistor template ), I wrote like this: void visitStoreInst(StoreInst &SI) { //Get the refference of the types Module *M =

IR code that I obtain is the following: > > i8* bitcast ([5 x i8] c"hello\00" to i8*) You need to put your "hello" in a (constant) global variable. You can then bitcast the address of the global to i8*. I suggest you compile some C code that makes use of the address of a
