Hi,
* regtested vzip/vuzp patch
* looked into big-endian build
* applied all the required patches and checked that Viterbi gets
vectorized giving ~2x performance improvement (compiled with
cross-compiler)
* looked into vld/vst implementation - mostly discussions with Richard
* DenBench analysis:

Hello,
* Analyzing DENBench benchmarks.
* Running mp3 player on Crotex A9 with gcc-linaro -r99463 using SMS flags
(*) gives 21% improvement in execution time compared to using only base
flags(**).
(*) -fmodulo-sched -fmodulo-sched-allow-regmoves
(**) -mcpu=cortex-a9 -mtune=cortex-a9 -mthumb -
