[LLVMdev] About loop information in LLVM during compiling

[Jim Grosbach]

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
