(+linaro-toolchain, which I dropped at the start)
I had a hack and set up a chroot on my Tegra 3 OUYA to run distcc.
With the Wandboard driving and a 'ninja make -j12', LLVM 3.3 built in
75 minutes (meh). You really need the 2 GiB of RAM - the 650 MiB left
on the OUYA plus the occasional four 250 MiB g++ hurts.

* Nice holidays in Brittany.
- Wine, cheese, more wine, some beaches...
* ODroid buildbot still running...
- After a long and hot week with all windows close (room temp > 25C), the
bot has held stable no hotter than 63C and is running self-hosting
(partial+full build) without a single hiccup.
- I'd be very happy with them as buildbots (rather than Chromebooks)
- I'd also be very happy to test the ODroid X2 (octo-A15/A7)

* Initial investigation on cross-compilation issues

around)

* Wrote a patch to fix gas NEON addressing mode bug and committed
* Submit and respin of glibc malloc tests and fixes
* Pushed cortex-malloc test and benchmark suite to git.l.o

* Further malloc work
* Get glibc patches applied upstream
* Complete wiki cleanup

Hi,
I was trying to build a gcc-linaro that targets AArch64 (mostly
following guides such as http://jk.ozlabs.org/docs/arm64-toolchain/) and
failing, to be short and simple. Unfortunately I don't have the errors
I was encountering to hand, so instead I'll ask: Is the build process
for building aarch64-linux-gnu-gcc and friends documented anywhere?
Cheers,
mwh
