== Progress ==
* Lots of little changes to the Jenkins configure files and
Cbuildv2 so Jenkins can do a builds in a 32 bit chroot. (4/10)
* Misc - meetings and misc tasks (2/10).
* Helped with binutils & GCC releases. 4/10)
* New Arndale Octa arrived.
== Plan ==
* Get back to adding the neon intrinsics tests to the GCC
testsuite.
* More Jenkins hacking for 32bit chroot builds.
* More hacking on binary release automation.
* Review Kugan's benchmarking support in Cbuildv2.
== Issues ==
* Loosing ssh access to many of the machines we work on is a
problem...
== Leave ==
* A bit complicated. On the road till Jan 13, offline some, mixed with
some work days depending on the weather. Should have email
access most nights.
Hi All,
I am getting a weird error while building binutils from
http://cbuild.validation.linaro.org/snapshots/Latest/binutils-linaro-2.23.2…
GCC version gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu9)
Ubuntu 13.10
Steps:
1)
/work/sources/binutils/configure --target=aarch64-unknown-linux-gnu
--prefix=/work/builds/gcc-fsf-trunk/tools
--with-sysroot=/work/builds/gcc-fsf-trunk/sysroot-aarch64-unknown-linux-gnu
2)
make
(Snip)
gcc -c -DHAVE_CONFIG_H -g -O2 -I.

Can anyone point me what is going wrong here.

== Issues ==
* none
== Progress ==
* LRA on AArch32:
o TCWG-343 : Make LRA the default for the ARM backend (8/10)
- Validated and committed a fix from Vladimir for Thumb1 issues.
- iWMMXT issue : Tried a fix without success, continue working on it.
o TCWG-345 : Analyse performance of LRA for ARM. (0/10)
- No progress this week.
* Various meetings. (2/10)
== Next ==
* Vacation
== Progress ==
* Debugged and Fixed process record memory corruption problem.
[TCWG-315][TCWG-317][8/10]
* Sick Time off [2/10]
== Plan ==
* Send patches for bug fixes and look into remaining arm-native gdb issues.
* Respond to maintainer's suggestion on process record patches.
* Public Holiday on 25th
* Time off for setting up new office space.
== Progress ==
* Libssp GCC patch
Replied to Marcus comments on libssp machine description support for
stack protect and test. Analyzed other ports implementations on
clearing register that loaded canary value. Waiting for his feedback.
* Pointer mangling Aarch64 glibc.
Investigated mangling support and implemented a patch. Testing glibc
test suites in V8 Foundation model is in progress.
* Attend Linaro Tool chain status meeting.
* Attend 1-1 with Christophe (Linaro).
* Attend 1-1 with Matt (Linaro) .
== Plan ==
- Pointer Guard support in Aarch64 glibc
- Continue tesing Cbuildv2
== Issues ==
* None.
== Progress ==
* Rebase aarch64 build scripts to crosstool-ng upstream, test and send
out the patch for community review (2/10).
* Investigate https://ci.linaro.org/jenkins/job/openembedded-armv8b-rootfs/gcc_version=4.….
It seams build configure issue. Some MICRO is not correctly defined.
Can not follow-up it due to no access to the build system.
* Continue on "uninit warning testsuite failures" (CARD 304 7/10)
- Identify another reason why uninit-pred-8_b.c FAIL: The control
flow is too complex, it can not normalize the condition at line 22 to
( n < 10 || m > 100 || r < 10 ).
- Work on patch to fix PHI issue to make uninit-pred-9_b.c PASS.
* Test builds for backporting "ftruncate() and truncate() stubs"
related patches in Linaro newlib.
== Plan ==
* Linaro toolchain binaries 2013.12 release.
== Progress ==

* Vectorizer
- Progressing on the implementation of the pragma parser
- http://llvm.org/PR18086
- Discussions about introduction of generic function vectorizer (ARM)
* Release 3.4
- Tested RC3, no regressions on tests or benchmarks
- http://people.linaro.org/~rengolin/llvm/
- http://llvm.org/pre-releases/3.4/rc3/
- Looked at a bug on the vectorizer for pentium3/freebsd
- Work around found, not easy enough to get them to RC4
* Background
- Many discussions, many support requests, many patch reviews
- Adding BOF notes to dev meeting site
- Booking train and hotel for FOSDEM 14
* Time
- CARD-862 8/10
- Others 2/10
* Happy Holidays! And see you in January!
== Issues ==
* Running benchmarks on my Chromebook is very unstable.
- Even though the standard deviation is small in two different moments,
the two results are statistically incompatible.
- The wireless network on the Chromebook, as widely known,
is unstable and unpredictable.
- I need a graphical interface, so I can do stuff during Connects,
or to see Phoronix results and that is probably the responsible
for all instability
- Next release, I'll use an ODroid (or Arndale) for benchmarks
== Plan ==
* Holidays!
== Progress ==
- 2013.12 releases (4/10)
* Handover to Michael
* Committed remaining backports/branch merges
* Unexpected regression in 4.7 branch narrowed to a linker bug, now fixed.
