[LLVMdev] printing constants

[anubham suresh]

Sir,

Given code like:
> 
>    X = add int Y, 1
>    Z = mul int X, 17

while I iterate over the  operands of the first
instruction i want to print the variable x ,as well as
the constant 1 and while i iterate over the second
instruction i want to print variable x and constant
17. 
what should I do?

thanking you,

yours sincerely,
anubham suresh
