[LLVMdev] How to transform loop to if-else using LLVM?

[Dmitry Mikushin]

Hi, Zhiyuan Yang,

Are you trying to replace the for-loop with equivalent if-goto loop? In
this case, do you also need a goto after i++?
LLVM IR in fact already contains exactly the goto-form of any loop, because
IR has no high-level constructs like for or while.
