Blueprint changed by kan hu:

Looks like these work are related to toolchain. Here are some my cents,

• GDB and Oprofiler on Cortex a9(required for profiling or look for a workaround) : TODO

We plan to improve the correctness of GDB and Oprofile on cortex-a9. If you find bugs on them, please file tickets in launchpad, and we can have a look.

• Check FFMpeg test application or write a new one to measure performance: TODO
• Select contents with different parameter setting for using measure performance. TODO
• Check current performance result and find a reasonable target performance: TODO

Speed performance improvement is one of our task also. Feedback on GCC performance on cortex-a9 are welcome.

• Measure and record performance increased by NEON optimize method: TODO

Recent Linaro GCC release includes some NEON improvements. This may be helpful to this task.
