llvm dev - May 2014 - [LLVMdev] loop identification

Hello everybody,

I have developed a pass to identify the loops in a bitcode file. For 
files less than 1500 lines of code I am able to identify all the loops, 
however if the file is bigger I cannot find any of the loops.
Is there any limit or something about the LoopInfo?

Regards,
Vasileios

Are all of these loops in one large function? I don't recall any such limits
in LoopInfo. It would be helpful to know what your pass is doing, what version
of LLVM you're using, etc.

Plus examples of the IR that works and another that doesn't. ;)
