I can generate the CFGs using 'analyze', but I am having trouble loading the profile data. I added the line AU.addRequired<ProfileInfo>(); to the getAnalysisUsage. It is returning zero for all the edge

For my own understanding, I wondered if using the opt command-line is the only way to request a ProfileInfoLoaderPass? What if I want to use this information in the 'analyze' utility instead of 'opt'? Also, rather than requesting the pass...
