Can you guys tell how to recognize local & global variables ? Is there any
macro on Value* defined in LLVM?

Global variable: isa<GlobalVariable>(V)
Local variable: isa<AllocaInst>(V)

Ciao,

Duncan.

Yeah that's true. But I want somewhat different. Through Instruction how do
u know that? If an instruction like %a = alloca i32 is there, how to get the
variable 'a' ? Then on that variable we can check as you have said
Right?
How to capture that variable ?
