I'm not really sure what you want to do.  If you're trying to print out 
all of the literal constants in instructions in a function, you can use 
the llvm/Analysis/ConstantsScanner.h interface to do this.  Something like 
this:

   Function *F = ...
   for (constant_iterator I = constant_begin(F), E = constant_end(F);
        I != E; ++I)
     std::cerr << *I;

Given code like:

   X = add int Y, 1
   Z = mul int X, 17

It will print out 1 and 17.

Is this what you mean?
