i answered that. the vast majority of the office around me uses 32bit and isn't
going to change in a hurry due to IT/security restrictions. this is 100's of
developers working on tizen all day, every day. not weekend hobbyists. :)

well that's fine. resources need allocation, but the point here i and clark
are making are that 32bit support is needed for various reasons, not just in
self serving "i need it" ways, but in much broader ways too.
the support can be dropped, but it will have consequences.

sure. that's the point of the request - get freedback on people needing/wanting
32bit x86 support. i responded. with more than just a selfish "i need it",
but with a more general and wide-reaching set of side-effects of dropping
such support. :)
personally i don't like the qemu misc binary emulation hack. it's cool and
neat, but really complicates a build env. i personally rather prefer a pure
cross-compile setup (ala OE) OR a full native build (so run qemu-system
emulation and a full os inside of it doing the builds - this also leads to a
nice bi-product of being trivial to "accelerate" by just slapping it on real
hardware and using a distcc cross-compile farm)
