llvm dev - Mar 2013 - [LLVMdev] static variables in the IR

How can I check if an operand is a static variable in the IR? 
I've read that their linkage type should be marked as "internal"
in the .s file,  but I can't find a way to test if an Instruction has static
variables as operands.
Can you help me?

Thank you in advance,

Niko

get the operand, for example:
   Value *Op = Instr->getOperand(0);
You probably want to get rid of any type casts:
   Op = Op->stripPointerCasts();
You can test if it is a global variable using:
   if (isa<GlobalVariable>(Op)) { ... }
If it is, you can cast it to a global variable and test the linkage:
     GlobalVariable *GV = cast<GlobalVariable>(Op);
     if (GV->hasLocalLinkage()) { ... }

Ciao, Duncan.
