When I use the llvm to print out the code, it actually gives
out the number of uses for each variable, for example, I get
lines like this:
%S.i = alloca %struct.SimpleStruct ;
%cast216.i = getelementptr %struct.SimpleStruct* %S.i, long 0,
ubyte 0 ; <int*> [#uses=1]
My question is how the program knows about the number of uses.
If I want to check all the future uses of this variable, say
%S.i. Is there a way that I can directly find the uses of this
variable? Or I have to iterate over the function, inspect all
the instructions and ompare all the operands of each
instruction to see if they are the same?
