Yep, but I changed more things from then. I have it in a local tree.
I will send it to gcc-patches once I teach it how to deal with gimple
(I don't remember if you sent me the patch that disables computed gotos,
but I think that's easy to rewrite it if it's missing.)

Yep, this could help improving code quality when used with DCE,
(and even when we have a goto loop with an induction variable...)
