llvm dev - Aug 2010 - [LLVMdev] About loop information in LLVM during compiling

Hi, all
	Can we get the loop information in LLVM during compiling? In which
phase or function we can obtain the loop related information?

Thanks
May

Hello,

I'd suggest starting by having a look at the LoopInfo analysis pass in
lib/Analysis/LoopInfo.cpp. Other passes which operate on loops use this pass via
getAnalysis<LoopInfo>. There are various examples of usage in
lib/Transforms/Scalar/Loop*.cpp.

Regards,
  Jim
