== Progress ==
* spec2k comparison between ARM and x86
- More benchmarks analysed.

- Woking on vrp based zero/sign extension elimination based on feedback
- Started addressing comments for divmod optimization
== Plan ==
* Continue with spec2k comparison between ARM and x86
* Wiki Cleanup
== Progress ==
* GDB Record and Replay (TCWG-197)
Completed writing most of gdb process record Thumb32 instruction handling code.
Created test data for various types of Thumb32 instructions
Performed testing fixed some coding mistakes and bugs.
* Visa Application
Filled US visa application online for LCU13.
Prepared US visa documentation to file visa immediately after coming
back from UK.
Made travel arrangement for UK visit.
== Plan ==
* GDB Record and Replay
Integrate gdb process record thumb32 support patch with gdb source and
perform testing.
Submit patch upstream.
* Travel and Visas
Collect travel information and travel to Cambridge UK by Sunday.
* Days Off
Thursday and Friday off for a small visit to Dubai before reaching UK on Sunday.
== Progress ==
* Started setting up a GCC git mirror on git.linaro.org.
* Tweaked Cbuildv2 & Jenkins to work with GIT repositories as well
as source tarballs.
* Jenkins now "bootstraps" a cross compiler by building the native
GCC, and then using that to compile the cross GCC.
* Got aarch64-none-elf building with newlib via Cbuildv2.
* Finished binary tarball release support in Cbuildv2.
* Almost got Canadian crosses building via Cbuildv2.
* Continued work on Jenkins/Cbuildv2 integration.
* Added ccache support to Cbuildv2.
* Cbuildv2 now works on Fedora as well as Ubuntu.
== Plan ==
* Finish setting up GCC git repository with Linaro branches
fetched from svn and bzr.
* Add support for building source tarballs.
* Continuing with Jenkins/Cbuildv2 integration. (waiting for GCC
git repository to be complete)
* Get Jenkins to upload binary & source tarballs to
snapshots.linaro.org.
* Finish getting Canadian Cross builds working in Cbuildv2.
== Issues ==
* Still waiting for Odroid hardware to get shipped.
* Waiting for git-bzr-ng to be installed on git.linaro.org.
* Git-svn is incredibly slow on initial fetch. (fetching the
linaro/gcc-4_8-branch has been running over 24 hours)
== Progress ==
* Worked on getting glibc benchtests into shape for string functions
* More wiki cleanup (done?)
* Backports and release of eglibc 2.18 2013.09
* Booked Cambridge trip for Sept 17th
== Issues ==
* None
== Plan ==
* More improvements to glibc benchtests for strings/malloc if possible
* Get back to malloc and stack guard work

== Progress ==
* Backports for 2013.09:
- committed several
- reviewed
- submitted a few new ones
* Wiki pages cleanup
* GCC trunk cross-validation:
- need to work around results instabilities caused by incomplete
threads support in QEMU.
== Next ==
* Release 2013.09 next week after completing the latest backports.
* Resume investigation on perfomance regression with peeling disabled.
* GCC trunk validation: work on reporting
* Book hotel/plane for Connect
== Progress ==
* Cross-compilation
- Cleaning up v7A cores and features in Clang
- Writing document on how to cross-build using Clang/LLVM
- Creating bugs to deal with the issues found
- Adding LZMA library dep to cross-build in LLVM
- https://cards.linaro.org/browse/TCWG-200
* Divmod 64
- Long discussions about libcalls using registers with ARM
- Trying to revive my old patch due to future improvements from ARM
- It should also help future improvements on value_in_regs attributes, as
well as other library calls in registers or with multiple return values
- https://cards.linaro.org/browse/TCWG-199
* Maintenance
- Patch reviews, discussions, as usual
- Investigating breaking test-suite bot
- Added two pandas to the lab for general use
== Plan ==
* See that all patches created this week get through
* Have a look at automating Phoronix (via Jenkins)
* Find SLP-vectorizer regressions on ARM and fix them
Progress:
* rebased and fixed last issues in aarch64 prep patchset, sent it
out with a note that I'm going to put it in a pullreq to be
applied unless any further comments come up in review
* reviewed Christoffer's GIC save/restore patchset
* reviewed and cleaned up toolchain's QEMU wiki pages

Hi folks,
Since we won't be using Pandas for buildbots any more, I decided to put
them in the lab for general use. This is not LAVA or CBuild managed, and
the purpose is to test, and possibly benchmark, small applications, build
systems, native compilation, generated code, etc, in real hardware. For
this purpose, the Pandas are great, so there you have it.
There is no reservation mechanisms, but the etiquette is to "who" and
"top", and if you're the only active user, go for it. Multiple users can
use a single board if only testing, compiling, running code, but if someone
is benchmarking, would be polite to use the other board.
They're sporting a Linaro 13.03 release with kernel 3.5.0. If you need/want
access to them, just let me know.
cheers,

== Progress ==
* Backports for 2013.09:
- updated list, assigned some to team members
- submitted several requests
- quite a few of them exposed dependencies, making it necessary to
make several attempts.
* Aarch64 frame layout: posted sample code using large frame on
gcc-patches to get feedback.
* Disable-peeling: resumed regression investigation.
* Wiki pages cleanup
* trunk validation:
- continued to work on internal validation of trunk using our
compute farm (build+cross validation) to help catch regressions early.
== Plan ==
* Finish backports, sort out dependencies problems.
* Disable-peeling: investigate regression
* More wiki pages cleanup
* trunk validation: improve reporting
* install Ubuntu on Chromebook
