Hi!

* V8 - SunSpider
The pieces for building in cbuild and parsing with the
linaro-toolchain-benchmark scripts are in place. Ran the SunSpider
benchmark across a few toolchains with the o2-neon and o3-neon variants.
I have documented my work on this page, but not analyzed the results yet.

What worries me is that there is too much variation in some of the test
results. Probably caused by the garbage collection kicking in at
unpredictable times. I will try to monitor the gc and investigate if it can
be controlled somehow.

I would like to do a gcc-4.4 run as well. Android's original toolchain is
based on gcc-4.4.3(?) and that is what I compared against when doing
measurements internally.
However, I have problem compiling C++ with gcc-4.4 - it is this one again:
home/asa-san/cbuild/slaves/ursa3/gcc-4.4.5/gcc-binary/bin/../libexec/gcc/armv7l-unknown-linux-gnueabi/4.4.5/cc1plus:
/home/asa-san/cbuild/slaves/ursa3/gcc-4.4.5/gcc-binary/lib/libstdc++.so.6:
version `GLIBCXX_3.4.14' not found (required by /usr/lib/libppl.so.7)


* Handed over daily tasks to Zhenqiang.

Åsa
