Tom,

My understanding was that all IEEE floating-point implementations followed the same rounding rules, etc?  Is that not the case?

Are the SIMD subsystems not IEEE compliant, for performance reasons?

As said, I'm not an expert in code-optimisation.

I did look up the discussions. It was more then "a few weeks ago", they date back to January this year. :-)

There are two discussions that might be interesting:
http://sourceforge.net/mailarchive/forum.php?forum_name=freetel-codec2&viewmonth=201301

"c2dec produces different wav-files on i386 and on ARM" and "adding compiler flags"


Cheerio! Kr. Bonne.
