[LLVMdev] How to insert two instructions with the same name?

i want to insert a PHI into one basicblock like this:

%s.1 = phi int [ 80, %entry ], [ %tmp21, %bb17 ]

then, insert a cast inst. into another basicblock like this:

%s.1 = cast int %s.1 to uint

But, when i do this, the llvm automatically change the same name into a new

Actually, i found that sometimes, llvm will create bytecode containing two
instructions with same name. So, how can i implement that?
