Create the GlobalVariable which have extern in one header file
.... I already have an extern for that global in a header file to use it in the following way
extern const void* DATA_TABLE[];
And with a LLVM PASS, I am trying to create this array with the same name and with initializer. So, I have following:
GlobalVariable *gvar_data = new GlobalVariable(
M, blockItems->getType(), true, GlobalValue::CommonLinkage,
blockItems, "DATA_TABLE");
gvar_data->setAlignment(16);
gvar_data->setSection("data_section");
gvar_data->addAttribute(llvm::Attribute::OptimizeNone);
I am not sure if I am using the correct Linkage or not.
The pass...

[cfe-dev] Create a BlockAddress array from LLVM Pass
...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) {
BlockAddress *bba = BlockAddress::get(fn, *it);
listBA[Idx] = bba;
Idx++;
}
Constant *blockItems =
ConstantArray::get(ArrayType::get(?, 8), listBA);
Thanks

Create a BlockAddress array from LLVM Pass
...balVariable *gvar_ptr_abc = new GlobalVariable(
/*Module=*/*fn->getParent(),
/*Type=*/PointerTy,
/*isConstant=*/false,
/*Linkage=*/GlobalValue::InternalLinkage,
/*Initializer=*/0, // has initializer, specified below
/*Name=*/"labelTracker");
gvar_ptr_abc->setAlignment(16);
Constant *blockItems = ConstantDataArray::get(fn->getContext(), tmp);
gvar_ptr_abc->setInitializer(blockItems);
I get error with following: Unsupported type in Type::getScalarTy
Can anyone suggest what I suppose to do? It is definitely related to my type declaration and BlockAddress items, but I don't know...

Create the GlobalVariable which have extern in one header file
...ize mismatch?
Here is my code:
GlobalVariable *old = M.getGlobalVariable("DATA_TABLE");
old->setAlignment(16);
old->setSection("data_section");
old->addAttribute(llvm::Attribute::OptimizeNone);
old->setDSOLocal(false);
GlobalVariable *gNew = new GlobalVariable(
M, blockItems->getType(), false, GlobalValue::ExternalLinkage,
blockItems, "DATA_TABLE");
gNew->setAlignment(16);
gNew->setSection("data_section");
gNew->addAttribute(llvm::Attribute::OptimizeNone);
