After doing the GIMPLE_MODIFY_STMT work, I've come to the conlusion that to continue overloading trees will be more work in the long run than doing the actual separation between tuples and trees. This business of "this is a tree, but not really", includes far too much special casing. It seems it's best to bite the bullet now and separate the data structures in one sweep.
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. Gr. Steven
