Amber noticed this on her Twitter feed: a L4 microkernel based
para-virtualisation that runs on the A9:

They're currently running the 11.12 LEB on a Versatile Express. The
project overview:
http://l4dev.org/codezero_overview
talks about their 'hyperswitch' method to reduce the
para-virtualisation overhead and reduce the number of changes to the
Linux kernel.

The GCC release tested up just fine. The branch is now open for commits.
The next release is Thursday the 9th of February. Note that this is
in the middle of Connect.

The Linaro Toolchain Working Group is pleased to announce the 2012.01
release of Linaro GCC 4.6 and Linaro GCC 4.5.
No changes were made in Linaro GDB this month and, as such, no release
has been made.
Linaro GCC 4.6 2012.01 is the eleventh release in the 4.6 series.
Based off the latest GCC 4.6.2+svn182894 release, it contains a few
bug fixes from over the Christmas break.
Interesting changes include:
* Updates to 4.6.2+svn182894
Fixes:
* PR51301 ICE in vectorised widening multiplies
* LP: #897583 Code generation bug with -O2 (-foptimize-sibling-calls)
* LP: #736661 armel FTBFS due to compiler ICE
Linaro GCC 4.5 2012.01 is the seventeenth release in the 4.5 series.
Interesting changes include:
* Updates to 4.5.3+svn182893
Fixes:
* LP: #736661 armel FTBFS due to compiler ICE

The Linaro Toolchain Working Group is pleased to announce the
release of Linaro QEMU 2012.01.
Linaro QEMU 2012.01 is the latest monthly release of
qemu-linaro. Based off upstream (trunk) QEMU, it includes a
number of ARM-focused bug fixes and enhancements.
New in this month's release:
- Several bug fixes which reinstate support for running on ARM hosts
- Support for previously missing *xattr syscalls in usermode emulation
- A (dummy) model of the L2x0/PL310 L2 cache contrnoller (thanks to
Rob Herring and Mark Langsdorf of Calxeda)
Known issues:
- Graphics do not work for OMAP3 based models (beagle, overo)
with 11.10 Linaro images.
The source tarball is available at:

Hi Åsa. Well, the first proposals have arrived. I've cc'ed this to
linaro-toolchain so we have a record.
First, visit:
http://ex.seabright.co.nz/helpers/proposals
and see there are new merge requests from Ulrich with new results.
Next, login:
http://ex.seabright.co.nz/helpers/login
Your login is your Launchpad OpenID login "https://launchpad.net/~asa-sandahl"
After logging in, go back to the proposals page.
See that the fwprop-subreg merge request has a i686 and x86_64 result.
The i686 one is fine so click 'Record' and follow your nose. The
x86_64 is interesting - the fault might be real. Click 'Record'.
Note the subject line has 'regressed' in it. Ulrich will have to
investigate.
The lp-879725 results look fine so record both of those. Scanning
down the page shows that everything else is recorded so you're done!
The tool is a bit slow so don't be surprised if an operation takes ~10
s. The tool is backed by a cache so you won't see the results for ~2
hours.

Hi Michael,
I can't remember if I told you before, but I shall be away at the
CodeSourcery (Ok, Mentor Graphics's ESD TOOLS) annual meeting most of
next week.
I ought to be back at work on Friday. In the meantime I shall be reading
email, but not spending much time on Linaro work.
I can probably still get the GCC release process done, but if you'd
prefer Ramana did it this month then that's fine with me.

Hi there. Linaro is about what's next and, as part of this, we should
backport any reasonable Cortex-A15 changes to our 4.6 branch.
Richard and Matthew, could you let us know directly when new patches
from ARM land upstream?
We're already doing this but I thought I'd say it out loud.

Hello,
I'm trying to build the Linaro GCC from source on an x86_64 Fedora 16 box.
I'm using as a guide a wiki entry I found in linaro.org site [1] that
explains how to build a native version of the compiler. But instead of a
native version I want to be able to cross-compile ARM binaries for my
target machine.
This is what I tried:
[javier@munra src]$ wget -c
http://launchpadlibrarian.net/86993387/gcc-linaro-4.6-2011.12.tar.bz2
[javier@munra src]$ tar xaf gcc-linaro-4.6-2011.12.tar.bz2
[javier@munra src]$ mkdir build && cd build
[javier@munra build]$ ../gcc-linaro-4.6-2011.12/configure
--target=arm-linux --disable-bootstrap --enable-languages=c
--prefix=/home/javier/tools
[javier@munra build]$ make -j4 && make install
But got this error:
make[2]: Leaving directory `/home/javier/src/build/gcc'

Before trying to compile I've installed the libgmp, libmpfr and arm cross
tool-chain [2] Fedora packages so I guess all gcc dependencies are met
(binutils, glibc, etc).
Could someone be so kind to point me out what am I doing wrong? I'm sending
as an attachment the config.log generated file.
Please let me know if you need any more information about my setup and
environment.
