similar to: [LLVMdev] Question about Constants

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

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

Hi all; I have been trying to use the llvm::ConstantArray::get(llvm::LLVMContext&, llvm::StringRef, bool) function but seems it has been deprecated. ProfileDependence.cpp:68:73: error: no matching function for call to ‘llvm::ConstantArray::get(llvm::LLVMContext&, llvm::StringRef, bool)’ ProfileDependence.cpp:68:73: note: candidate is:

Hi, I tried passing the array directly using and changing the getorInsertFunction accordingly but this didn't work. It fails with Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed. hookFunc = M.getOrInsertFunction("hook", Type::getVoidTy(M.getContext()),

I'm trying to create a GlobalVariable that is a ConstantArray. Id like each element to be a pointer to other things in the program(global variables, functions). So that they all have the same type Id like to make the elements void pointers. I think I am going about this wrong, heres how I am doing it: void writeArray(Module &M, GlobalVariable *shadow, Function *val,

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)

Hi all, I am new to LLVM, and I am learning how to use LLVM for profiling. I need to pass an array to an external method, and insert a call instruction to the method in the code. After reading a few source files, I've tried using GetElementPtrInst to pass an array, but it fails at llvm::GetElementPtrInst::hasAllZeroIndices() const + 0 std::vector<Value*> Args(1);

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]

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

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 =

>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

Let me clarify my question. I have a struct array h1 as follows: dhash h1[10]; I want to get a Constant* to variable h1. It looks like I can use ConstantStruct::get(StructType*, ArrayRef<Constant *>) to do this. My question is how to get the second argument of type ArrayRef<Constant *> from the above variable h1.

OK here's a new version of the patch - and the unions.ll test actually passes :) On Mon, Jan 18, 2010 at 1:40 PM, Chris Lattner <clattner at apple.com> wrote: > > On Jan 16, 2010, at 11:15 AM, Talin wrote: > > OK here's the patch for real this time :) >> >> On Fri, Jan 15, 2010 at 4:36 PM, Talin <viridia at gmail.com> wrote: >> Here's a work
