similar to: [LLVMdev] Declaring constant global variables

Can I do this in my own pass module? Because the string is actually depended on the type of a value object.

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]

>The type you pass to GlobalVariable's constructor for that variable should be "[10 x %struct.dlist]" because that's what you want storage for. Then the GlobalVariable itself will be a Constant of type "[10 x %struct.dlist]*". Yes, I verified that this is the case. I enabled assertions and the error seems to occur while creating GlobalVariable for both struct dhash

I'm a bit confused. For the Type did you mean something like: ArrayType *type = ArrayType::get(Type::getInt8PtrTy(M.getContext()), 4); This does not work, it gives me ""Wrong type in array element initializer" at runtime. Also it doesn't look like ConstantExpr inherits ConstantArray, so I'm not sure how I could use this instead. Thanks On Thu, Oct 20, 2011 at

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'm trying to create a ConstantArray(whose contents will be of types Function*, GlobalVariable *) so I can immediately create a new GlobalVariable(that will be in its own section). I'm doing this so I have these address stored. In order to create this ConstantArray I need a valid ArrayType, but I'm not sure what to use for the element type. I want this to be done at compile time, so I

Hello, I'm trying to get the pointer to the first element of a string (so that I can pass it to a function). The string itself is a constant kept in a global variable. My end goal is to generate the IR for something like "puts("Hello World")"; I'm stuck on the parameter part of the call instruction. So far I have something like this: const std::string& str =

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 =

Thank you very much. The code to initialize h1 to non-zero values was what I was looking for. It's almost working except for a type mismatch wrt dlist* llist field of h1. dlist static_lst[10] = { {1, 5, NULL}, ... }; dhash h1[10] = {{"myfile.txt", static_lst}, ... }; Along the lines of the code you had sent, I created a GlobalVariable* llist of type [10 x %struct.dlist]* for the

Hello, I want to add a global variable of arrayType in my MachineFunctionPass. However, I only get const Module from MachineFunction.getMMI().getModule(). I can't add any global variable to a const Module. Another way is to add a global variable in doInitialization in my MachineFunctionPass, but I can't determine the size of my arrayType for global variable in doInitialization. Is there

Sorry for emailing both group. As I will have a constant array of BlockAddress, what type I should use in Constant Array for its ArrayType declaration? I am creating the list in following way: unsigned int nBr = fit->second.size(); llvm::Constant *listBA[nBr]; unsigned int Idx = 0; for (std::set<llvm::BasicBlock *>::iterator it = fit->second.begin(); it != fit->second.end(); ++it)
