armv6: Accelerate butterflies_float
I benchmarked the result by measuring the number of gperftools samples that
hit anywhere in the AAC decoder (starting from aac_decode_frame()) or
specifically in butterflies_float_c() / ff_butterflies_float_vfp() for the
same sample AAC stream:
Before After
Mean StdDev Mean StdDev Confidence Change
Audio decode 1542.8 43.7 1470.5 41.5 100.0% +4.9%
butterflies_float 130.0 11.9 70.2 12.1 100.0% +85.2%

floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.
Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also. |
