--- Comment #4 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Evan Teran from comment #3) > Any unsupported feature would do. All the core features are at least partially supported, only some ABI-breaking library changes have been postponed. > A quick read of that page shows a pretty good solution. Has any word towards > implementing its recommendations been done? I don't think so. Feel free to start. Defining a bunch of macros seems like a nice and easy way to start contributing to gcc ;-)
