pass and a LoopPrinterPass with the expected associated wiring. I've added a RUN line to the only test case (!!!) we have that actually prints loops. Everything seems to be working. This is somewhat exciting as this is the first analysis using another analysis to go in for the new pass manager. =D I also believe it is the last analysis necessary for porting instcombine, but of course I may yet discover more. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226560 91177308-0d34-0410-b5e6-96231b3b80d8
