1 i'm pleased to announce the initial x32 release candidate:
4 the x32 ABI is the default one, and includes x86/amd64 ABIs. it is not using
5 /lib32/ (and /lib is not a symlink) like our existing amd64 multilib as that
6 is being phased out, and the x32 port allows me to do a clean break.
8 i call this a release candidate as it is using glibc-2.15 with backported
9 patches. the ABI however should be the same as glibc-2.16, so hopefully the
10 upgrade will go smooth. but i don't want to make an official release on the
11 chance that things aren't smooth, so this is a release candidate.
13 once glibc-2.16 is released upstream, we should have x32 stages released
14 alongside the existing x86/amd64 stages.
16 caveats:
17 - you have to be running linux-3.4+ with the x32 ABI enabled in your config
18 - the x32 profile has marked toolchain packages stable ahead of other arches:
19 - linux-headers-3.4
20 - binutils-2.22
21 - glibc-2.15 (and will have stable glibc-2.16)
22 - gcc-4.7.0
23 - strace-4.7
24 - gdb-7.4.1
25 - gdb will probably be flaky, but the new gdb-7.5 release should address that
27 so if you try running stable amd64, you will hit some failures unrelated to
28 x32, but related to the newer toolchain packages. this will get better over
29 time as other packages go stable, and i'll be trying to push at least
30 binutils/linux-headers stable soonish.
32 for the adventurous souls, please review the existing x32 tracker bug:
34 and file new bugs for packages you come across that aren't yet known
