Michael Niedermayer	90e9e94d0f	workaround gcc bug, untested as my gcc is not complaining Originally committed as revision 10236 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	cefa599953	optimize the first vertical lifting step, this also prevents another overflow, the last known possible overflow Originally committed as revision 10234 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	8b5029295d	get rid of totally senseless "m" + read in register we have enough registers to keep everything in registers Originally committed as revision 10229 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	bc1e78d896	simplify senselessly complex addressing Originally committed as revision 10228 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	25bb359f73	cosmetics remove brain amputated mmx wrappers around sse2 macros fix name of ..._sub macro to match ..._add naming Originally committed as revision 10227 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	629750290f	avoid overflow in the 3rd lifting step, this now needs mmx2 at minimum (patch for plain mmx support is welcome ...) Originally committed as revision 10226 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	b696a4c91d	avoid an overflow in the 1 horizontal lifting step Originally committed as revision 10225 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	9caa1cccb9	prevent one overflow in the first vertical lifting step Originally committed as revision 10224 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	3e0f7126b5	update mmx code to latest snow changes note, the code likely can overflow and thus needs some more changes sse2 updated too but disabled as it is untested Originally committed as revision 10223 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	ce611a27be	Change rounding of the horizontal DWT to match the vertical one. This allows some simplifications and optimizations and should not have any effect on quality. Originally committed as revision 10172 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
