[llvm-dev] distinguish program and temporary variables

[Mohammad Norouzi via llvm-dev]

Hi,

I need to check if a variable belongs to the program originally. Consider
the following code line:

y = x + 4

and its corresponding llvm ir (roughly):

%16 = load i32 %x
%add = add i32 %16, i32 4
store i32 %add, %y

I need to distinguish between %16, %add and %x, %y.

Any help is appreciated.

Best,
Mohammad
