In summary the actions from the meeting are:
* ACTION: Matt update meeting template attendees - to include Yvan
* ACTION: mgrettondann split LRA blueprint
* ACTION: Christophe to update Hot/Cold partitioning bugzilla
* ACTION: mgrettondann: benchmark on Hold/Cold partitioning
* ACTION: Christophe to look at the loop peeling cost
Thanks,

This patch provides support to detect the host architecture in
configure.in use the detected architecture to conditionalize parts of
the Makefile.am. The intention is that we retain a single top level
Makefile which contains rules relevant to all supported architectures,
each gated by the AM_CONDITIONAL infrastructure.

Folks, In preparation for adding aarch64 string functions into
cortex-strings, I'd like feed back on the following series of patches.
1/5 Trivial whitespace cleanups.
2/5 Autotools foo for cross building support.
3/5 Autotools foo for architecture detection.
4/5 Missing LDADD and CFLAGS setting.
5/5 Use --std=gnu99
I'm particularly interested in views on 3/5. This patch sets
direction for autoconf detection of the host architecture. The
intention is that we retain the single toplevel Makefile.am which
gains AM_CONDITIONAL support for the detected host triple.
The aarch64 specific code will follow in a different patch set.
Cheers

Hi,
the issue seems indeed to be introduced by r193959 and fixed in
r194161, as it is reported in:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55571
Unfortunately, my merge attempt was at r190461 :(
I redo the merge...

Summary:
* Validate RM toolchain, Linaro QENU 2012.12 and Linaro aarch64 2012.11.
* Collect performance data for different branch cost.
Details:
* Validate RM toolchain release.
* Set up test environment with the help of Michael and validate Linaro
QEMU 2012.12 release.
* Validate aarch64 toolchain 2012.11. From 2012.12, it will be
released regularly like arm-linux-gnueabihf toolchain.
* Collect denbench and spec2000int performance data for branch cost tuning.
* Investigate how to do copy propagation for shrink-wrap to optimize
453.povray benchmark. Will reuse current codes in pass_cprop_hardreg.
Plans:
* Performance reports for branch cost tuning.
* Fix README issue (lp:1068402) in Linaro crosstool-ng.
Best regards!

Hi all，
I am a rookie, and now I'm focusing on ARM virtualization. As we know,KVM (for Kernel-based Virtual Machine) is a full virtualization solution. KVM-Autotest is a set of virtualization tests for X86 platform, but it may not be suitable for ARM.I want to know, in the linaro , what tools can protect the KVM and qemu quality ? Thanks and Regards,Qun Chen
* usual set of meetings etc
* rebased qemu-linaro on upstream 1.3, rolled tarball for 2012.12;
Zhenqiang has tested it and it should be ready to go next week
* qemu arm patch catchup; pinging or resending some patches of
mine from before upstream freeze
* applied a set of boot-wrapper patches from tixy
* virtio patch code review: design definitely coming together now

-- PMM
== Progress ==
* Turn off 64-bits bitos in Neon: Ping-ed patch proposal.
* Disable peeling: benchmarks show good results; sent a proposal
upstream to discuss preliminary implementation & needed testsuite
modifications.
* builtin_bswap16 backport to linaro-4.7: need to investigation an
unexpected regression reported for i686 target.
* Updated gdb linaro sources to 7.5.1, exercising the release process.
* Trying to bootstrap gcc-linaro/4.7 on board: need to retry with a
different rootfs distribution.
== Next ==
* handle 64-bits bitops in Neon and disable-peeling feedback from
upstream if any.
* finish builtin_bswap16 backport
