Strange ARM results with iOS device #32

Closed Codewyvern closed 9 years ago

Codewyvern commented 9 years ago

Can someone please answer this question, have you tried to run the ARM neon code on an iOS device? I am getting very incorrect values with ffts_init_1d_real forward transform starting with any signal size 16 and above. I am testing with i = i + 1 so 1,2,3,4... etc.

At this point I have tried this master branch and a few forks but it seems like no matter what I try there is something wrong with the results on ARM. The same exact code I have works perfectly with SSE but gives completely wrong results on ARM.
