...generating edge count profile by the PGOInstrumentationGen pass and then interpreting the edge count profile with PGOInstrumentationUse. In the original code, where I had au.addRequired< ProfileInfo >(), I now have *au.addRequired< BlockFrequencyInfoWrapperPass >();au.addRequired< BranchProbabilityInfoWrapperPass >();* Now, I have the following queries. - How do I use the edge count and branch weights data obtained using PGOInstrumentationUse in my pass and replace the *getEdgeWeight()* from ProfileInfo? - If I call *getBlockProfileCount() *from the BlockFrequency pass, will that give me...

...of "opt -irce test.ll" invocation, which does not work with a direct translation to "opt -passes=irce test.ll". It only works with explicit   opt -passes='require<branch-prob>,irce' test.ll Legacy pass manager version of IRCE does have an explicit dependency on BranchProbabilityInfoWrapperPass and that automatically installs that analysis into the pipeline before irce. How do I express that kind of dependency with new pass manager? If I did not miss something obvious that already handles these kinds of dependencies then what should be the best way to go? - Add BPI to LoopStandardAnal...
