The upstream gcc and newlib are OK. But since binutils and gdb are now in a single repo, it will need to come from the github site until it is merged upstream. And obviously patches just need to go upstream to whereever the code is. :) Jeremy also encouraged you to openly discuss things on their forums. He thought you would get good insight and advice there. And I don't doubt that. If it is a relatively low volume place, I may track it. But my email volume is already high and I don't have time to poke around on a bulletin board. > It will not have RTEMS as a target but that shouldn't be hard to address once > we know where the master binutils, GCC, Newlib, and gdb are.
