Fix issue #301:
summary of changes: - Use MANGLE when loading some constants into MMX registers. - Convert those constants to non-static and thus add ff_ prefix. - Remove last parameter of MSPEL_FILTER13_CORE (was constant). - Use of "+r" instead of stricter but unnecessary "+g". - Use of REG_c and direct loading of some of the above. patch by Christophe GISQUET, christophe.gisquet free fr Subject: [FFmpeg-devel] [PATCH] Roundup issue #301 Date: Fri, 28 Dec 2007 19:22:18 +0100 Originally committed as revision 11376 to svn://svn.ffmpeg.org/ffmpeg/trunk
