Extended Description

llvm2cpp generates incorrcect code in the following case:

1. compile the following function to substitute_bug.bc:

#include <stdio.h>

extern "C" void NewMarker1()
{
printf("NewMarker1 \n");
}

2. lvm2cpp -f -gen-function -funcname=makeNewMarker1 -for=NewMarker1 substitute_bug.bc -o
   substitute_bug.bc.cpp

Function* makeNewMarker1(Module *mod) {

// Type Definitions

FunctionType FuncTy_0 = FunctionType::get(
/Result=/Type::VoidTy,

/isVarArg=/false,
/ParamAttrs=/FuncTy_0_PAL);

PointerType* PointerTy_1 = PointerType::get(IntegerType::get(8));

ArrayType* ArrayTy_3 = ArrayType::get(IntegerType::get(8), 12);

PointerType* PointerTy_2 = PointerType::get(ArrayTy_3);

std::vector<const Type*>FuncTy_5_args;
FuncTy_5_args.push_back(PointerTy_1);

label_entry);
CallInst* int32_tmp1 = new CallInst(func_puts, ptr_tmp, "tmp1", label_entry);
int32_tmp1->setCallingConv(CallingConv::C);
int32_tmp1->setTailCall(false);
new BranchInst(label_return, label_entry);

// Block return (label_return)
new ReturnInst(label_return);
return func_NewMarker1;
}

The "const_array_7" constant definition is missing from the generated code.
