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...

Hello, llvm developers! I am running LLVM with JIT on ARM. For simple programs it runs ok, but for lager code I have stumbled upon some issues. See following C++ code to which I have reduced the problem: #include <stdio.h> struct Global { typedef unsigned char ArrayType[4]; ArrayType value; Global(const ArrayType& arg) { for (int i = 0; i < 4; i++) this->value[i] = arg[i]; } }; static const unsigned char arr[] = { 1, 2, 3, 4 }; static const Global Constant(arr); int main() { for (int i=0; i<4; i++) printf("%i", Constant.value[i]...

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 cant use a BitCastInst to make them all generic pointers. What else can I do? In other words * I built up a vector id like to eventually store as a GlobalVariable array: vector<Constant *>...

What else can I do? You can use a ConstantExpr (constant expression) for Function and GlobalVariable objects. The A...

.... affinityElement.__bits[0] worked fine for me, thank you. I am new in using the API for Constants and I am facing the error "incomplete type is not allowed" on the last last of below code: Type * ET = IntegerType::getInt64Ty(I.getContext()); unsigned long size = cpuAffinityVector.size(); ArrayType * AT = ArrayType::get(ET,size); Internet gives different solutions for this error but none of them was appropriate for this case.

Hi Chris, > I'm happy about factoring the code better, but a vectortype isn't an > arraytype (isa<ArrayType>(V) should be false). Maybe a common base > class (like sequential type) would be better? currently anything you can do with an array you can do with a vector. So from this functional viewpoint it would make sense to have a vector be an array with more stuff (i.e. a sub...

Hiya, I want to declare a constant global variable as: @.str = private constant [4 x i8] c"%f\0A\00", align 1 ; <[4 x i8]*> [#uses=1] I guess I should firstly declare an arrayType object, then declare a GlobalVariable object. I have two problems: 1. What element type I should set for the arrayType? 2. How to set the constant value as :c"%f\0A\00" Cheers, Zheng
