== Issue ==
* AArch64 frame grows downward: no feedback yet.
== Progress ==
* Disable-peeling: Vectorizer cost model has been changed upstream,
quick look at benchmark results show little difference between before
and after the change. Need to analyze further, since I expected the
regressions previously identified with my patch to appear here too.
* AArch64 bootstrap failure: succesfully bootstrapped in the model.
* GCC trunk validation:
- improved configurability (default cpu, fpu, mode, testsuite flags
are selectable)
- requested feedback to build the list of desirable combinations to validate
* Backports/release 2013.10
- a few more backports completed
- re-trying to backport the ILP32 and refactoring series proves
again to be tricky, but helped identify backports which had escaped
from the list.
- cbuild has disk full again
* GCC Neon intrinsics testsuite:
-- posted a proposition to add my executable tests to the existing
framework. No feedback yet.
== Next ==
* Make 2013.10 releases, both with the historical process and using
cbuildv2, in parallel
* Disable-peeling/new vectorizer cost model: analyze bench results
== Progress ==
* Got cbuildv2 google group setup.
(https://groups.google.com/a/linaro.org/forum/#!forum/cbuildv2)
* Got email notifications working for commits to cbuildv2 repository.
* Continued work on release building via Cbuildv2. Source tarballs
checked out OK, binaries too. Probably a few tweaks left to cover
the minor differences, which are all documentation files.
- Rebuild GCC dynamically so the shared libraries for libgcc and
libstdc++ can go in the runtime binary tarball.
- Build runtime binary tarball.
- Added install script to sysroot tarball.
- Make overriding the default release tag with a user supplied
one work fully.
* Got Odroid U2 board working again, did complete native build
using cbuildv2.
* Reviewed more cbuild2 patches from Ryan.
* Got Jenkins building snapshot tarballs.
== Plan ==
* Do slides for Connect presentation.
* Work on duplicating the 2013.10 release via cbuildv2.
* Get Odroid X2 board to boot, which it currently refuses to do.
* Try to work around problem with importing test results.
* Copy tarballs to snapshots.linaro.org.

(CST2 - CST1) == 1 into ((X - CST1) & ~(CST2 - CST1)) == 0" according
to comments.
* Continue on CCMP
- Send the phiopt patch to handle CCMP for community review. Jeff
will follow-up it.

Toolchain Working Group, Linaro
== Progress ==
* EEMBC
- Updating Linaro image with Clang toolchain changes
- Updating compare_all script to rank boards
- Investigating differences in performance against GCC
* ODroid XU
- Setting up server image (Linaro 13.09 + odroid specific changes)
- CPU scheduler is a mess, forcing "performance" governor at boot seems to
work
- No journal in root fs, remounts ro all the time (bad image?)
- LLVM builds are slow (as fast as Chromebook), maybe it's the SDCard
- Setting it as self-host buildbot in the lab, going well
* Background
- Massive patch review (Sub-Register Live Range Analysis for NEON/VFP et
al)
- LLVM Sync and EuroLLVM meetings
== Plan ==
* Continue investigating performance problems in EEMBC
* Check Odroid XU internal buildbot for stability
Hi Term,
I have try to us "crosstool-ng-linaro-1.13.1-4.8 "to build myself cross tool chain,
but some problem happened,just before I have used crosstool-ng offcial version,
every thing is fine,I have got my toolchain, my operation system is Ubuntu 12.10,
when I change to crosstool-ng-linaro,
I am follow these steps.
ct-ng list-samples,
ct-ng linaro-arm-linux-gnueabihf
ct-ng menuconfig
I just change Local tarballs directory ,Prefix directory ,and change target os from
prebuilt to linux,
then,I build it,first time error happened at step "cc_core_pass_1 ",I google it
and found out it is about multilib,I need to install gcc-multilib and g++-multilib,
then,I continue,this time,error happened at step"cc_core_pass_2 ".
