- 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...

* 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>

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:
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
