Dear LLVM'ers (or whatever name you will soon have),
I want to create a pass option, that I could pass at command line, and that would be visible among many different MachineFunction passes. It would be something like the join-liveintervals used in LiveIntervalAnalysis, but I want my option to be visible among many passes, and not only one. I browsed the documentation, but I did not find the info I was looking for. Could any of you tell me a little about it?
I mean, do I have to write something like:
cl::desc("Join compatible live intervals"),
in some .h, and then include it in every pass that would read EnableJoining? Is there a standard way of doing this?
