...dct.c...where most of the vectorization occurs...these files lean towards a 50% speedup. Anyhow, if someone wanted to get these changes into a mainline libvorbis, they should: - diff libogg and libvorbis from that CVS. - Make sure the build system #defines MACOSX=1 and gcc is invoked with the -faltivec command line (-O3, -ffast-math, and -falign-loops=16 are huge helps, too). - Change the _al_has_vector_unit() define in misc.h to point to a static variable in libvorbis and set that variable in a convenient place during initialization. Currently this variable exists in my AL implementation and...

Well, if what you want is auto-detection, turning on -march=pentium3 means that the code will crash on anything lower than a pentium3. Not really useful. Of course,

When compiling Speex 1.1.4 with GCC 3.3.2, the option -msse must be added to the CFLAGS in libspeex/Makefile. GCC 3.1.1 added a new option "-msse" (see http://gcc.gnu.org/gcc-3.1/changes.html , specifically under "New Targets and Target Specific Improvements") to enable SSE instructions within the compiler's output (for appropriate architectures).
