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-th...@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. r~ Richard Henderson (1): meson: Deprecate 32-bit host support docs/about/deprecated.rst | 8 ++++++++ meson.build | 6 ++---- 2 files changed, 10 insertions(+), 4 deletions(-) -- 2.43.0
