== Progress ==
- Monday was a public holiday
- Studied benchmarks and analysed the rtl/asm for redundant sign extensions
- Came up with simple test cases based on this (have 6 test cases now)
- Looked at gcc tree documentations and helper macros; tried it by
adding more debug dumps for types at tree level
== Plan ==
- Start with the algorithm for sign extension elimination
- Skipping manual changes at source level/asm level to see the
performance improvement for now.
Short week...
== Progress ==
* Catch up on internal tasks / email that piled up during holidays + Connect
* Resumed work on disable-peeling:
- local benchmarking on snowball
- restarting benchmarks via cbuild for an additional check
== Next ==
* Check benchmark results on disable-peeling
* Have a look at how to dejagnu-ize my Neon intrinsic tests
* Check results of libsanitizer branch
* Check results of 'revert-coalesce' branch
* Check bench results of '4.7-backport-vect-cost-model'
* Check bench results of '4.7-turnoff-64bits-ops'
* Investigate why cbuild did not generate all the comparisons I
expected (*-diff.txt files)
* Check whether 2013.03 release process exposed the same problems I
observed with 2013.02.
Progress (in a 1 day week...):
* qemu maintenance:
** released qemu-linaro 2013.03
** arm-devs pullreq
* VIRT-4 [Guest migration support for KVM]
** audited vexpress code for migration issues: there are a few
devices needing minor cleanup, and one (pflash_cfi01) which
has no migration support at all and needs it writing
* KVM other:
** reviewed virtio-blk refactoring patchset
-- PMM
== Progress ==
* Recuperating from Connect, catching up on email
* Attended David's and Maddog's presentation on Monday
* Investigating Arndale bug (seems to work with new kernel)
- Bootstrapping LLVM works, GCC doesn't
* Reviewing patches upstream (Mans', Tim's, others)
* Fixed three bugs on test-suite that depended on RNGs
- Only two more tests broken only in ARM
- Five others broken on both (but only visible on our bot)
- Nine EH tests that need disabling, for now
== Plan ==
* Tackle the two last ARM specific bugs
* If time allows, clear the other 5
* Try to disable any EH-specific test on ARM
* Start talks about getting an internal binary distribution process going
This is to let you know that the migration of lists.linaro.org has been
successfully completed.
As per the email I sent on Wednesday, it may take some time for the new
address of the server to be seen by your computer. You can check this by
trying to connect to the web site:
http://lists.linaro.org/
If you are able to connect and you do not get an error, this means you are
connecting to the new server and you can send email to the lists.
If you experience any problems after the weekend and you find that you
still cannot connect to the server, please reply to this email to let us
know.

The Linaro Toolchain Working Group is pleased to announce the release of
Linaro QEMU 2013.03.
Linaro QEMU 2013.03 is the latest release of qemu-linaro. Based off
upstream (trunk) QEMU, it includes a number of ARM-focused bug fixes
and enhancements.
This release has been updated to be based on upstream's recent 1.4.0
release. It also includes ARM KVM support patches which are in sync
with the ABI as committed to the upstream Linux kernel for 3.9.
This feature is still under development but will no longer be subject
to kernel-vs-userspace ABI breaks.
The source tarball is available at:
https://launchpad.net/qemu-linaro/+milestone/2013.03

Hello
You are receiving this email because you are subscribed to one or more
mailing lists provided by the lists.linaro.org server.
IT Services are announcing planned maintenance for this server scheduled
for *Friday 15th March 2013, starting at 2pm GMT*. The purpose of the work
is to move the service to another server. There will be some disruption
during this maintenance.
In order to ensure that you do not accidentally try to use the service
while it is being moved, the current server will be shut down at 2pm.
A further email will be sent on Friday afternoon to confirm that the
migration of the service is completed. However, due to the way servers are
found, it may take a while before your computer is able to connect to the
relocated service.
After the old server has been shut down, email sent to any of the lists
will be queued, but it is possible that the sending server will still
trying to deliver the email to the old server rather than the new one when
it is started.
It is therefore *strongly* recommended that you do not send any email to an
@lists.linaro.org email address until you can connect to the new service,
which you will be able to test by trying to use a web browser to connect to
http://lists.linaro.org after you receive the email confirming that the
migration has been completed. Since the old service will be shut down, if
you are able to connect, you can be sure you have connected to the new
service.
If by Monday you are still unable to connect to the service or you are not
able to send email to an @lists.linaro.org email address, please send an
email to its(a)linaro.org.
Thank you.

Linaro
== This Week ===
* Couldnt help my luck and wasnt able to reach Hong Kong due to delay in
visa processing by Hong Kong immigration department.
* Remotely attended live streams of Linaro Connect Asia
* Tried to reproduce all open bugs under linaro-gdb project on launchpad
and created a review sheet.
* Created a comparison sheet to figure out why certain gdb tests are
failing or not being run in different configurations.
== Next week ==
* Try to enable some native only tests and see if the functionality can be
tested for remote configurations as well.
* Set out some priority on blue prints and bugs under linaro-gdb project
and start with some stuff with higher priority.
* Caught some flu over the weekend and still a bit down with fever n
headache.
