The last I heard on the gcc development list was that DJ Delorie and Nick Clifton (both Redhat) are officially appointed as gcc maintainers for the port, and checked in support on 12/09/2013. I guess that means it will be released with gcc 4.9 - but it should be fine as an example for the OP's use. > > I would add that out-of-tree, it works well and supports Ada very > nicely. I don't know how much of the gcc port was changed when Red Hat took it over (with TI paying the bills) and moved it in-tree. Some of it had to be changed or re-written due to copyright issues. I know that a lot of the library and support code was re-done, and I think this is based on newlib-nano. First priority is obviously for C, followed by basic C++ (typically without exceptions, RTTI, and limited library support - but that's what embedded users generally want anyway). I can't say anything concrete about the state of Ada, but my guess is that the code generation will work but the library will be limited. > > Thanks, > - Brian > >
