If we're worried about machine compatibility of SSE2, it may be helpful to
note that it was introduced with the Pentium4 in 2000 and the Athlon64 in
2003. With the exception of the Quark line of processors, no important x86
processor in recent years has lacked SSE2 support.

I cannot say for this specific case. If you
Thanks.
I should probably start a new subject, but I have related questions. Please
don't feel obligated to answer ... I'm just curious.
1) What would affect the ability of an embedded FLAC firmware to decode certain
files?
Is it possible that the SD702 is not capable of processing complex

Playing Devil's Advocate here, but isn't the point of compression standards
like FLAC that encoders can vary quite a bit, so long as decompression always
produces the correct results? In other words, I think it might be taking it too
far to require that the encoder produce identical results on

Hi Martijn,
Great work!
I concur with David that compression should work the same on all
platforms. There can be SIMD optimizations for some routines, but they
should produce the same result as the non-SIMD versions. If outdated
optimizations cannot be updated, better drop them instead of
Martijn,
Just a lone voice here, but I would opt for the best compression on the
most platforms. As I am one of the people who always run FLAC at the
placebo max compression, my vote will always be for best compression over
any other resource use.
I also can make ARMv7 hardware available to you
