== 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 ==
- cbuild2 benchmarking
- Resolved access issues and imported into repository
- continuing with the missing implementations
- 64bit division for ARMv7-A
- Algorithm is committed to trunk
- enablement patch is posted for review
- trunk bootstrapping issue
- Setup foundation model and resolved space and kernel panic issues
- There is a assembler compatibility issue with older assembler
(-mabi=lp64); trying with the latest binutils
- AARCH64 bootstrapping in progress with this
- AARCH32 bootstraps with glibc but ran into issues with eglibc.
== Plan ==
- Address zero/extension review comments
- investigative bootstrapping issues
- continue with cbuild2 benchmarking
== Issues ==
* None.
== Progress ==
* Commit the fix for test case (lp1243022.c) by skipping arm-neon.
* Spawn arm-none-eabi build for Linaro 2013.11 release.
* Report PR59282: SPEC2K 252.eon ICE.
* Rebase conditional compare patch to trunk and tests.
- Update simplify_while_replacing to skip swapping compare in
conditional compare.
- Check whether operands of gen_ccmp_next clobber cc or not.
- Add a short description about the over all algorithm.
* Investigating loop-invariant impact on SPEC2K INT for x86-64 and
ARM. Testing is ongoing,
== Plan ==
* Continue on CCMP.
== Planed leaves ==
* Dec 3 & 5: Annual leaves
== 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
== 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 ==
* Finish refactor of cbuild2 to use git parser.
* 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}.
* Add lib/git-parser.sh and testsuite/git-parser-tests.sh.
* Fix corner cases with <user>@<url>/<repo>.git[/branch]@<revision>
1) Allow http urls to be processed by 'git' cases.
2) Error check git-new-workdir and git checkout
3) Parse revision and branch properly when there might be a <user>@
in the url.
* testsuite/test.sh: Update for breath to cover
user@<url>/<repo>.git@<revision>
* Fix get_srcdir to work with <user>@<repo>.git/branch@revision
* Fix get_toolname and get_srcdir when using <user>@<repo>.git@revision
== Issues ==
* None
== Next ==
* Have cbuild2 start using the git parser
== Issues ==
* Still some cbuild oddities.
== 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:
