[PATCH 0/1] meson: Deprecate 32-bit host systems

[Richard Henderson]

Time for our biennial attempt to kill ancient hosts.

I've been re-working the tcg code generator a bit over the holidays.
One place that screams for a bit of cleanup is with 64-bit guest
addresses on 32-bit hosts.  Of course the best "cleanup" is to not
have to handle such silliness at all.

Two years after Thomas' last attempt,

  https://lore.kernel.org/qemu-devel/20230130114428.1297295-1-thuth@redhat.com/

which resulted only in deprecation of i686 host for system emulation.
By itself, this just isn't enough for large-scale cleanups.

I'll note that we've separately deprecated mips32, set to expire
with the end of Debian bookworm, set to enter LTS in June 2026.

I'll note that there is *already* no Debian support for ppc32,
and that I am currently unable to cross-compile that host at all.

Showing my hand a bit, I am willing to limit deprecation to
64-bit guests on 32-bit hosts.  But I'd prefer to go the whole hog:
unconditional support for TCG_TYPE_I64 would remove a *lot* of
32-bit fallback code.
