== Progress ==
* Setup 64 bit centos-5 and suse-10 chroots for testing binary
tarballs, and used them to verify the Cbuildv2 produced ones
compile 'Hello World!", and run on a real target.
* Got remote chromebook testing working in TCWG build farm.
* Worked on getting GDB remote testing with gdbserver working.
* Did build and test run on aarch64 APM board of GCC
linaro-4.8-branch.
* Changed Cbuildv2 to disable parallel make jobs when building GCC
native on ARM or AARCH64 platforms, as the hardware can't handle
the load.
* Got the LSB tools installed and researched what they do.
* Debugged why 32 bit binary tarballs made in a chroot won't run
when installed on multiple x86_64 systems. Works now by statically
linking everything.
* Got test results, converted to Junit format for Jenkins.
* More TCWG build farm admin issues.
== Plan ==
* Continue working on GDB remote testing in the build farm.
* More tweaks for binary releases.
* Continue trying to get GCC trunk to build on APM board.
* Figure out why Jenkins doesn't import the Junit files.
* Probably more TCWG build farm admin issues, which is probably
a continuing task, so I'll stop listing it every week.
== Issues ==
* If I try to monitor a Jenkin's build via the "Console", it
crashes my browser as the logs get huge.
* Long weekend for Thanksgiving holiday means short work week...
== Leave ==
* Off this coming Thursday for my birthday...

- O3: ~0.2% faster, ~0.7% bigger
- Os: ~1.3% slower, ~0.6% bigger
- Phoronix, ImageMagick: OK within std dev
* LLVMAndroid
- Tinti compiled the kernel 3.4 and some libs with LLVM

for Android
* Background
- Lots of patch reviews, discussions
- Helping Graphics WG with Clover
== Issues ==
Still ill because of implant, on/off throughout the week.
== Plan ==
* Put the self-hosting bot up once it's fixed
* Fix the XU bot
* Try LLVM Android on XU again
* Continue with the simple vectorization pragmas
* Waiting on benchmark test-suite mode to create a new benchmark test-suite
== Progress ==
* lib/git-parser.sh: Add support for ~ as branch designator and
multi-/ branches.
* Refactor cbuild2 to use git parser
* Created stamp functions for cbuild2
US Thanksgiving Holiday
== Next ==

* Create unified parser that wraps git parser.
* Finish refactor of cbuild2 to use stamp functions.
== Issues ==
* None
Forgot to hit send on this one
== Progress ==
* Add documentation for git-parser.sh.
* lib/git-parser.sh: Add no-url support.
* testsuite/test.sh fix invocation of testsuite/git-parser-tests.sh
to include ${topdir}.

in the url.

== Progress ==
* LRA on AArch32:
o TCWG-342 : UPSTREAM: LRA issue in gfortran with store minmaxsi
- Performance validation is OK, confirmed by kyrill.
- Waiting for approval.
o TCWG-344 : UPSTREAM: Thumb bootstrap failure with LRA
- Pinged for THUMB_SECONDARY_INPUT_RELOAD_CLASS patch review
- Validate and post patch for PR58785:
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg02459.html
o TCWG-345 : Analyse performance of LRA for ARM
- Analysing results mismatch between 2 pandas
- Configured and ran spec2000 on Chromebook
- Analysis ongoing
== Next ==
* Continue on LRA
* Reviews
== Progress ==
* Released GCC 4.7 and 4.8 2013.11 releases.
* Investigated potential regressions on trunk, as reported by
continuous cross-validation.
Reported some cases to Kyryll. Another, reported to Bin, turns out
to be an unrelated, unstable testcase recently introduced.
Will have to give a closer look at big-endian tests.
* Updated libsanitizer patch for AArch64. It builds again but is not
functional yet (running in the Foundation model currently); getting
support from libsanitizer developers. Support for AArch64 will have to
be committed in LLVM, and merged into GCC later. I'm going to continue
prototyping under GCC though, and will submit changes to the
libsanitizer team when ready.
* GNU tar regression (extended_negsidi pattern): posted bugzilla,
fixed by Richard.
* cbuildv2: gave another try, pointing to staging.g.l.o, to discover
that it was outdated too. Rob has fixed it since then.
* Backports: gave some support to Michael Collison to help him get to speed.
Prepared backport of Zhenqiang's "enhance phiopt
to handle BIT_AND_EXPR" (TCWG -303)
== Next ==
* Resume "disable-peeling" work. Mostly check that the current trunk
contains what we want.
* cbuildv2: retry to create source release 2013.11
* Backports: commit TCWG-303, and Charles' backport of his testsuite fix
look at the others in the list.
* libsanitizer for AArch64: make it functional
== Progress ==
* GDB ARM Process Record:
- Completed work on arm process record Advance SIMD, vfp and coprocessor
instruction recording.
- Submitted initial patch for SIMD. VFP and coprocessor instruction
decoding.
- Resubmitted previous patches after incorporating suggestions.
- Resolved patch line wrap issues and formating issues.
* Macau visa and travel planning
* Got started with using concur
== Plan ==
* GDB ARM Process Record:
- Follow up on previous patches.
- Test VFP, SIMD and other advance instruction types recording.
- Fix issues and submit their fixes if any.
* Run GDB testsuite in various configurations and analyze failures.
