Hello Jonathan, Just FYI, I started doing review of your patch and will get back to you in few days. After review, I would like to rebase your patch (as necessary) myself and do some testing.. and re-submit.

Using GCC 4.9.2, decoding the opus test vector set 10 times. All tests pass. I will do longer tests later with a larger test set, but it looks good so far. I am having a lot of trouble with the Ne10 detection. Using the precompiled Ne10 binaries at http://people.linaro.org/~viswanath.puttagunta/opus/NE10_root/ Both NE10 and Ne10 capitalizations seem to be in use. Also, where should the NE10 headers be installed? In $PREFIX/include or $PREFIX/include/Ne10/? The configure.ac tests seems to assume the former, but your precompiled root disagrees.

Hello opus-dev, Can we please have review on RFCv2? We have quite a few optimizations (Eg: ifft/mdct_backwards, fixed point fft/ifft mdct_forward/backward etc) that are in my pipeline that depend on this patch series being accepted.

...on the hook to rebase after your fix goes in. Looking over your patch quickly, I don?t think any of my changes should be that difficult to merge with yours. I haven?t studied your patch in depth yet. Does Ne10 use its own RTCD code, or do you use Opus?s?

Sorry for typo.. from shows as "--no-chain-reply-to --thread ./*" instead of from "Viswanath Puttagunta". So resent it again after fixing my command line.. Otherwise, the patch for RFCv2 is identical.

Hi, Can you apply this change to the MDCT test and run it again. See if more (all) sizes pass. Given the results, I strongly suspect an overflow.

I'm trying to get these cleaned up and landed, but I'm running into some trouble with this patch. Using commit a08b29d88e3c (July 21) of Ne10, I'm seeing test failures for 60-point FFTs: nfft=60 inverse=0,snr = -3.312408 ** poor snr: -3.312408 ** nfft=60 inverse=1,snr = -16.079597 ** poor snr: -16.079597 ** All other sizes tested appear to work fine (84 to 140 dB of SNR).
