* armv6: Accelerate butterflies_floatBen Avison2014-07-16
| | | | | | | | | | | | | | 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% Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| * floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | | | | | | | | 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.
