Given we see multiple organizations with an interest in this work, but that the bulk of the work can't be integrated in the short term, y'all might consider a shared development branch for coordination. That gives the two organizations a place to coordinate their work while things like the ISA spec and such get solidified. Presumably the goal for the main body of work is not gcc-14, but gcc-15. I don't want to dictate how coordination happens. Ultimately it's something the relevant developers can decide. jeff
