I've done some minor updates to the instructions for working with
gcc-linaro, bzr, and merge requests at:
https://wiki.linaro.org/WorkingGroups/ToolChain/BzrTips
The interesting changes are using:
* bzr commit --fixes=lp:nnnn to link a branch to a bug number
* bzr branch --hardlink to cut down on branch time and disk usage
* bzr-merge-changelog to automatically merge ChangeLog.linaro

Greetings,
I successfully built BusyBox using the 4.5.2 toolchain. When I try to build BusyBox using the same config with the 4.6.3 toolchain I get the following error:
The Linaro 4.5.2 toolchain was installed in my Ubuntu 11.04 distro using aptitude.
The Linaro 4.6.3 toolchain binaries, downloaded via Launchpad, were installed into my own tools directory.
busybox # make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
scripts/kconfig/conf -s Config.in
can't find file Config.in
make[2]: *** [silentoldconfig] Error 1
make[1]: *** [silentoldconfig] Error 2
make: *** [include/autoconf.h] Error 2
I get the same error if I try 'make oldconfig' or 'make menuconfig'.
Is there a PATH I need to set? Am I missing a package?
Right now my PATH has following 4.6.3 directories set:
linaro-4.6.3/bin
linaro-4.6.3/arm-linux-gnueabi/libc/usr/include
linaro-4.6.3/arm-linux-gnueabi/libc/lib/arm-linux-gnueabi
linaro-4.6.3/arm-linux-gnueabi/libc/usr/include
Thanks,
Dan
I thought I'd send an update on the SPEC 2000 twolf variance. We're
seeing a high amount of variance in the results for the SPEC 2000
twolf, vpr, and galgel benchmarks. I've run tests on a PandaBoard,
Origen, and IGEPv2 and gotten a coefficent of variance of 0.014,
0.017, and 0.003 which suggests that the problem is Cortex-A9
specific. twolf is hard on the cache so my theory is that it's
something to do with the memory subsystem. I currently have a
PandaBoard running with SMP, heap randomisation, virtual address
randomisation, and the branch predictor off and the CPU down clocked
to the non-overdrive 600 MHz. I'll let this run overnight and see if
the results are tighter.
To solve Andrew's immediate problem, I'm running SPEC on the 64 bit
core register shifts on the OMAP3. The results are tight enough that
we should be able to show any regressions.
