[MPlayer-dev-eng] [PATCH] Improve MMX/SSE support on OS X/Intel

[Valtteri Vuorikoski]

The attached patch allows cpudetect.c to detect the usability of SSE/ 
SSE2 instructions on OS X/Intel and allows mp3lib to be compiled. SSE  
support for mp3lib is enabled, but MMX isn't due to (as far as I  
understand) use of addressing modes not supported by the Apple  
assembler in tabinit_MMX.c.

I have used the patch from http://trac.videolan.org/vlc/browser/trunk/ 
extras/contrib/src/Patches/ffmpeg-svn-mactel.patch to fix the MMX/SSE  
assembly used in libavcodec. This patch seems reasonable to me in  
that it doesn't make any changes in functionality and seems otherwise  
clean except that the /nop -> "nop" conversion as such is not  
portable. What the heck is "/nop, %mm0" anyway?

Besides that issue, are there other arguments against using the vlc  
patch?

With these changes plus my earlier DLL support patch, it should be  
possible to cleanly ./configure;make the command-line mplayer on OS X/ 
Intel.
