Create the GlobalVariable which have extern in one header file
...ave 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 has failed to complete it. Here is the runtime fault. Any guess what I am doing incorrect?
'common' global must have a zero initializer!

[LLVMdev] Disabling certain optimizations at -O1?
Could we move this setting to function attributes?
We already have OptimizeForSize / MinSize there, but not the other opt
levels. We also have OptimizeNone, which seems to be completely
unused.
This would let us support __attribute__((optimize())) in the future,
which is currently ignored.
Another example would be an LTO link of objects compiled with
different optimization settings. I'm not sure if anyone would want
this in practice.

Create the GlobalVariable which have extern in one header file
...Why it is creating another global variable instead of linking? Is that because of array size 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::Optimize...

My example was a very crude example of simplicity. But the more
complex your application is, the simpler you want the compiler to be
for a debug
