Diego Pettenò	be449fca79	Convert asm keyword into __asm__. Neither the asm() nor the __asm__() keyword is part of the C99 standard, but while GCC accepts the former in C89 syntax, it is not accepted in C99 unless GNU extensions are turned on (with -fasm). The latter form is accepted in any syntax as an extension (without requiring further command-line options). Sun Studio C99 compiler also does not accept asm() while accepting __asm__(), albeit reporting warnings that it's not valid C99 syntax.

Michael Niedermayer	61240ae556	fix chroma mc2 bug, this is based on a patch by (Oleg Metelitsa oleg hitron co kr) and does slow the mc2 chroma put down, avg interrestingly seems unaffected speedwise on duron this of course should be rather done in a way which doesnt slow it down but its better a few % slower but correct then incorrect Originally committed as revision 8093 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
