Hi all, I've patched theora-mmx to build on x86_64. The patch against SVN is attached. Basically all I did was to copy lib/i386 to lib/x86_64 and tweak the assembler code a bit: * added to each file: typedef unsigned long int ogg_uint64_t * converted all asm inputs to 64-bit in: dsp_mmxext.c, fdct_mmx.c, recon_mmx.c * left all asm outputs at 32-bit * I didn't patch dsp_mmx.c, since all x86_64 processors have SSE, thus there's no need for the old mmx version I also made minor modifications to cpu.c to get CPUID working correctly on x86_64. I've tested the patch usin...

...4 and replace .rept .. .endr with #defines. but to makes things more complicated apple's GAS does not support movsx instructions and thus the following line does not work: " movsx %%di, %%edi \n\t" [ more details at https://trac.xiph.org/browser/trunk/theora/lib/ x86_32/dsp_mmx.c#L443 ] if anyone has an idea how that could be replaced or written in a way that it works on OS X, please let me know. making asm optimization available for os x intel would be nice. j -------------- next part -------------- A non-text attachment was scrubbed...

quite some speed improvement indeed. attached the updated patch to apply to svn/trunk. j -------------- next part -------------- A non-text attachment was scrubbed...
