Did you just become my latest hero? Yes you did, yes you did!
I think it's very brave of you to draw this conclusion, and my guess
is that it is the right one ;-) . I hope you can get some folks to
help you. I'll try if I can.
Wrt. the locations discussion, people have suggested you can look at
other compiler's IRs, which seems like a good idea. But you may also
want to check out how INSN_LOCATORs work in RTL. There, we keep the
file/line info on the side, which seems to work rather well.
