Hi,
Tony removed support of ia32 binaries back in 2010. ia32 support was
supposedly broken since Al Viro killed altroot in 2008 [2]. I've no
clue what altroot is and what's its relationship with ia32 support,
but even without altroot, x86_64 still can execute ia32 binaries, a
(large?) part of the ia32 support coming from ia64 [3]. How is that
x86_64 can run ia32 binaries and no more ia64? There was also talk
about merging ia64 implementation with x86_64 one some times ago [4],
but I don't know how all this ended (by copying part of ia64
implementation into x86_64 as alluded to earlier? In this case, it's
code duplication, not merge).
An alternative is using Intel's proprietary IA-32 EL software, that
cannot be found anymore on Earth...
How do you deal with (rare) ia32 binaries on ia64 nowadays?
