Same as for D (bug 940470). As I mentioned in https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=799693623d76c89e8b04d2434d0dfece44bb49f9: """ Remaining bits to be done: * Adapting/replacing/supplementing dev-lang/gnat-gpl with a version that can be installed in parallel to sys-devel/gcc:10 so it can be pulled in transparently for bootstrapping; * ... """ We should perhaps copy dev-lang/gnat-gpl into dev-lang/ada-bootstrap (or dev-lang/gnat-bootstrap, whatever) and strip it down so it *only* builds Ada and it does so in a special location which doesn't collide with sys-devel/gcc:10. Later on, we can figure out building our own / sourcing our own binaries but that's separate.
Use this as a start: https://github.com/Lucretia/ada-overlay/tree/master/dev-lang/ada-bootstrap (needs reworking I think for the deps). And build script: https://github.com/Lucretia/ada-overlay/blob/master/scripts/build-bootstrap.sh It can be used for other languages from gcc which need a bootstrap too.

Thanks. We'll need it for D as well.

This ebuild was initially a clone of dev-lang/gnat-gpl-2021-r5 then had some cleanups done, toolchain.eclass use removed, and simplified what it configures/builds/installs. As I mentioned in 799693623d76c89e8b04d2434d0dfece44bb49f9, there were two jobs left -- this fixes the first one: splitting dev-lang/gnat-gpl into its own package which doesn't collide with sys-devel/gcc:10 and also does the least possible work, not with lots of USE, etc.) Some inspiration taken from sys-devel/bpf-toolchain. Considered using the *-toolchain name again but given the purpose of this is *not* just to avoid crossdev use but instead to bootstrap from a binary for Ada, it didn't feel appropriate. (Planned to do this anyway but the issue mentioned in 9732ef3475830dbe289fc80358613e90b612563c pushed me to get on with it now.) Later versions of ada-bootstrap will be our own binaries for both newer GCC as a base (although this is mostly a nice-to-have and to keep things building rather than it being essential, AFAIK) as well as more importantly musl and other arch support. For that future work, see https://bugs.gentoo.org/940471#c1 for a suggestion from Luke A. Guest. That will be tracked in bug #940472.

OK, the splitting / replacement part is pretty much done. I may need to polish it a bit more though. But the groundwork is there for bug 940472 now.

AFAIK it builds its own bootstrap (I've had it enabled since it got merged into gcc w/ no issues, including on new installs).
