[RFC PATCH v1] Decode(float) optimize using libNe10
Hello All,
I extended the libNE10 optimizations for float towards
mdct_backwards/opus_ifft.
I am able to get about 14.26% improvement for Decode use
case now on my Beaglebone Black. Please see [1] for measurements.
Questions
1. Since this patch needs to go in after Encode [2] patch)
should I submit this as patch series?
2. Since Jonathan Lennox posted intrinsics cleanup [3]
patch, should

Make check failure on clone from 31 January
Hi,
Apologies if this is a known issue, but running make on revision e3187444692195957eb66989622c7b1ad8448b06 fails one of the tests when using fixed point configuration (floating point is ok) on my linux x86.
Note that libopus1.1, as extracted from the tar ball, is OK.
Specifically, the tests that fail are in celt/tests/test_unit_mdct:
nfft=32 inverse=0,snr = 85.341197
nfft=32 inverse=1,snr =
