Basically I want to create the data IR for following C code:
extern int myarr1[];
int myarr2 = {(int)&myarr1, 0, 0};
So I created an llvm::GlobalVariable object for myarr1. But llvm asserted out and said it can’t be used as an initializer.
Wrong type in array element initializer
Is it possible to do this?
Got the answer:
llvm::Constant *cons = ConstantExpr::getCast(Instruction::PtrToInt, gvar_array_myarr1, IntegerType::get(mod->getContext(), 32));
Thanks!
