Fail to build and execute 'webkit' bench in Google compiler benchmark suite

[Jim Huang]

In AOSP, there is a benchmark suite developed by Google compiler team, and 'webkit' is one of the items. However, it doesn't really work. I encountered build failure and execution errors.

Messages:

The way to reproduce:

# cd toolchain/benchmark
# ../scripts/bench.py --action=build --toolchain=/tmp/android-toolchain-eabi
# adb push data /sdcard/perflab_input/
# ../scripts/run_on_android.py
../scripts/bench.py --action=runcmd

../scripts/bench.py --action=export
./out/libwebcore.so ./out/webkit_bench
adb shell rm -r /data/local/perflab

adb shell mkdir /data/local/perflab

my understanding is that the benchmark fails with our toolchain?

if so, same rational as in https://bugs.launchpad.net/linaro-android/+bug/732564/comments/3 applies for priority and milestone.

also setting to confirmed until we have an assignee and clarification that its just with our toolchain.

[Apr 6] sent mail to Google again to confirm if there is a duplicated work.

[Apr 6] Google compiler team is working on upgrading this to work with newer OS releases, but it will take some time.
