I’ve got instruction itineraries in a target schedule.td file. I’m wondering if they’re having much effect on the output code - is there a commandline switch to llc or opt that tells it to not use itineraries so I can examine the resulting assembly code? I’d like to be able to easily compare a .s file created with itineraries to one without itineraries without having to recompile all of LLVM - is that possible?
Also, are there commandline switches (maybe an option to -debug-only ?) that will output information about how the itineraries are impacting scheduling? (or output any itinerary info at all?)
