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

== 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
== Blueprints ==

* On x86_64 to see what the actual benefit we could get
* fix-gcc-multiarch-testing
* Come up with strawman proposal for updating testsuite to handle
testing with varying command-line options.
== Future ==
* backport-fma-intrinsic & fused-multiply-add-support
* Backport patches once fix-gcc-multiarch-testing has been done.

Is there any issue with the toolchain or any flags I am using?

Thanks and Regards,
Shiva.
I've done a couple of tweaks to the scheduler. You now see pending
jobs by the class of machine they'll run on. Clicking a job takes you
to the detail, which includes a link to drop/cancel the job.
