[LLVMdev] insert nop instruction
Hi.
I need to write a function pass that insert nop instruction in function.
Examples of these instructions are: %nop = add i1 0, 0 or %nop = alloca i1,
i1 0. This link couldn't help me:
http://llvm.org/docs/ProgrammersManual.html#creating-and-inserting-new-instructions
I need a clear example about inserting new instruction. Anyone can help me?
Thanks.
