== 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

The Linaro Toolchain Working Group is pleased to announce the 2013.09
release of Linaro eglibc 2.18, the first release in the 2.18 series.
This release is based on the latest upstream eglibc 2.18 stable branch,
but with additional features and bug fixes.
#### Additional Features
* None
#### Bug Fixes
* Fix for clone(2) built for Thumb2.
### Source
#### Release Tarball
* https://releases.linaro.org/13.09/components/toolchain/eglibc-linaro
#### Development Tree

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
== Progress ==
* Libssp support for AArch64 TCWG 23:
My approach to Cross testing eglibc from host failed since it needs
the build directories to be shared. Mounting the image in build
system and building eglic will not help as the changes will not be
reflected, in the image booted in V8 model dyanamically. The test
system only issues command via ssh but does not copy binary to the
model.
Need to try creating NFS mount from build system into the model.
* Backports
Lots of back porting and merging.
201624 and 201666 can be back ported together. Merge request submitted.
201406 to linaro branch. Small test case comment change. But the test
case fails in linaro 4.8, but passes in trunk.
It needs other revisions to be back ported, since vectorization
improvement in trunk. I tried back porting all relevant versions
r199402,r200394,r200600, r201282. But still fails since interface of
function get_loop has changed in trunk somewhere.
For 201411 look like need to hand pick and apply changes in arm.md
file. since lot of changes gone in that file and simple merge will not
be good. Also it may need some other revision to backport.
* TCWG-209, Looked at wiki pages, Christophe assigned to me and gave
some comments about updating/deleting them.
== Plan ==
* Post RFC patch for Libssp support for AArch64 in GCC
* GCC patch for gprof accepted, need to post patch in glibc.
* Continue testing the patch for Libssp support for AArch64 in GCC
and glibc TCWG-23. Try NFS mouting into the model.
* Backport 201411 201406 from trunk.
== Issues ==
* LTO/PGO work stopped now since libssp support priority is more.
== Issues ==
* None
== Progress ==
* Conditional compare (CCMP)
- Design tens of test cases to verify the codes.
- Handle CCMP in vrp pass. If the compare in CCMP can be simplified,
CCMP will be converted to a copy, compare or a bit operator.
- Investigating to handle CCMP in jump-thread related optimization.
- Investigating bootstrap issue when expanding conditional compare
to optimized RTL.
. It seams that there are illegal combinations of different
compares since bootstrap OK if the two compares of CCMP have the same
CODE.
. Current check bases on function "arm_select_dominance_cc_mode".
Need narrow down the root cause.
== Plan ==
* Continue on conditional compare.
== Panned leaves ==
* Sept. 3-6: internal meeting.
