== Progress ==
* 64bit division for targets without 32bit div instructions
- Finished the implementation
- Benchmarked it
- Getting ready to post RFC patch
* Connect Slides
- Worked on slides for connect
* Vector regression in 4.8-2013.09
- Started bisecting to find the issue
== Plan ==
* post RFC patch for 64bit division
* Vector regression in 4.8-2013.09
* Connect preparation
== Progress ==
* Improved the format of the emails that get sent to the cbuildv2
list from commits.
* Get Odroid U2 running stably, did native build on an external
USB disk. Upgraded to saucy. Did full toolchain build and test
run. 65 minutes per build.
* Got Odroid XU board to boot, then upgraded to saucy, not very
stable yet. Unlike the XU, it has a horrible lag when typing to
it via ssh.
* Updated chromebook to saucy, did native build and test run on
external USB drive. The U2 was faster, even with an older USB 2
only drive. 192 minutes for a build.
* Worked at verifying Cbuildv2 produced tarballs again since there
have been many little tweaks. The few differences between
Cbuildv2 produced tarballs and the official Linaro releases is
documentation related. For example, Cbuildv2 doesn't build the java
docs.
* Did slides for Connect presentation.
* Sat bagged an 900 foot ice route at over 13,000 feet. 8 mile
approach.
== Plan ==
* Try to work around problem with importing test results. (need to
work with LAVA team for this one)
* Copy tarballs to snapshots.linaro.org. (need to work with LAVA
team for this one)
* Get remote toolchain testing working on the newly functioning
Odroid board(s).
* Continued improvements to Cbuildv2.
== Issues ==
* My network and landline was down to upstream repairs for a day
and a half, bad timing during release week... :-(
Hi Bharath. Have a look under contrib/linaro/sysroot - there's a
script in there that you can fiddle with to pick a later distro.

Objective before Linaro Connect:
* Wiki/README on using cbuildv2 sources.conf and <package>.conf:latest=
* git workflow document: collaborative use of git in Linaro
* wiki/README on using cbuildv2 local_snapshots for
specific/non-remote archives or git repositories.
General Cbuildv2:
* Audit usage of "local foo=`bar`; if test $?". Change to: "local
foo; foo=`bar`; if test $?".
- This is a known issue and very nefarious.
* Investigate dryrun to use stderr 2>&1?
* Port get_URL, get_source, and find_snapshot to unique behind
<repo>/<branch>@<revision> return type.
* Test local_snapshot overrides

Hi,
We are working on userspace aarch64 and aarch32 apps and we are trying
to run 32/64 mode app simultaneously.
Is there any multi-arch support for mixed rootfs (has linkers/libs of
both arm and arm64)?

Thanks,
-Zhou
Progress:
* back from sabbatical!
* caught up on admin, email, etc
