armv6: Accelerate vector_fmul_window
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 vector_fmul_window_c() / ff_vector_fmul_window_vfp() for the same sample AAC stream: Before After Mean StdDev Mean StdDev Confidence Change Audio decode 1598.2 47.4 1529.2 25.4 100.0% +4.5% vector_fmul_window 244.0 22.1 188.9 22.3 100.0% +29.2% Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
