Few small questions - in context of latest oggenc2. When I do 3 simple tests:

oggenc2 -q8 test.wav
oggdec test.ogg -w check.wav

Then P4 and x64 give the same check.wav, but the result differs from generic version.

I presume icl version uses sse2 instructions, while generic one relies on x87 code (besides other optimizations potentially influencing the ogg encode) - so this is kinda expected.
Similary, rhe results are also different from vorbis-tools' oggenc (built against the same libs, but compiled with gcc on linux host).


This is I guess normal and nothing to worry about ?
