== Progress ==
* Disable peeling:
- spawned benchmarking jobs using recent trunk and another older
one to check for performance regressions.
- locally generated the code for the same benchmark to analyze the
differences
* cbuildv2:
- retried to create 4.8-2013.11 source release. Identified a couple
of minor issues, reported to Rob.
- for 4.7-2013.11, need support for subdir in git URLs, fix on-ongoing by Ryan
* Backports:
- gave some support to Michael
- a few have been reviewed/accepted.
* libsanitizer: little progress this week; advised to take a look at
recent LLVM sources.
* trunk validation: filed some bugzilla reports; 2 of them fixed by Kyrill.
== Next ==
* Disable peeling:
- check benchmarks results
- check code generation
* cbuildv2: re-do source releases 4.8 and 4.7 2013.11
* Backports:
- commit already approved ones, once cbuildv2 releases are OK
- see which ones can be easily added
- work on MULTILIB_DEFAULTS backport for 4.7
== Issues ==
* None.
== Progress ==
* LRA on AArch32:
o TCWG-342 : UPSTREAM: LRA issue in gfortran with store minmaxsi
- Committed as rev205526 .
- Card resolved.
o TCWG-344 : UPSTREAM: Thumb bootstrap failure with LRA
- Committed THUMB_SECONDARY_INPUT_RELOAD_CLASS patch as rev205527.
- Committed PR58785 patch as rev205581.
- Card resolved.
o TCWG-345 : Analyse performance of LRA for ARM
- Gathered results and analysis still ongoing.
o Working on a new failure with iWMMXT (LRA loops during constraints solving).
* Reviewed some merge requests.
== Next ==
* Continue on LRA
* Loop specialization patch review.
== Progress ==
* Investigated remaining testsuite failures in ARM process record/replay.
* Tested VFP, SIMD and other advance instruction types recording.
* Ran GDB testsuite in various configurations on gdb7_6_1 code base
and latest git repo.
* Learnt some prologue and epilogue analysis heuristics for resolving
process record bugs in arm.
== Plan ==
* Analyze test results from gdb testsuite runs in various configs and
update JIRA issues.
* Complete testing of VFP, SIMD and other advance instruction types
recording patch and Send updated patch.
* Try to find a epilogue analysis heuristics for resolving reverse
stepping issues in solib code.
== This week ==
- Completed backport of 202872
- Final checkin to upstream GCC SVN will be complete by Christophe Lyon
== Next week ==
- Begin work on other assigned backports
== Future ==
Document missing features of cbuild for backports
== Progress ==
- libssp gcc
Posted RFC V2 patch to community. Updated comments from Richard and
wating for some feed backs.
- Libssp glibc
- Sent out a patch for stack_chk_guard in Aarch64 along with TLS
stack guard support.
== Plan ==
- post RFC patches for glibc and gcc libssp
- explore on cbuildv2
29-11-2013 Friday - Leave (AMD internal event) .
== 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...
== Progress ==

* Buildbots
- Work-around for ClamAV (r195646), new bot in!
- http://lab.llvm.org:8011/buildslaves/linaro-chrome-03
- After a week stable, I'll deactivate the old chromebook and re-fit it
- Looking at MCJIT random breakages on A15 self-hosting tests
- http://llvm.org/PR18057
- Proposed a fix, http://llvm-reviews.chandlerc.com/D2287
- Installed Arch on the ODroid XU, running a local buildbot on it
- Investigating llvm-rtdyld but in reading debug information
- http://llvm.org/PR18085
* Vectorizer
- Mapping, discussing and proposing implementation for pragmas
- http://llvm.org/PR18086
- http://llvm-reviews.chandlerc.com/D2289
* Release 3.4 RC1
- Running benchmarks comparing 3.3 with 3.4
- EEMBC within noise levels for geomean
- 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
- Trying to put Android on the ODroid XU (the official one is quite poor)
- XU redirected to set as a buildbot, once ready, I'll use the other
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
