The assembler code is in SVN. The code is in routines:
filter_shrink_X_MMX, filter_expand_X_MMX, filter_shrink_Y_MMX and
filter_expand_Y_MMX.
Giving this more thought it is too late in the Pygame release cycle to
add an Intel translation of the assembly code to Pygame 1.8.0. This
would lead to four versions of each of four subroutines. The resulting
conditional expressions will be ungainly. Also the Intel translations
will need properly tested. The AT&T assembly code has been out for
awhile and shows no problems. For the moment a MinGW compiled
transform.pyd can be used in the Windows binaries for Pygame 1.8.0. But
it is desirable to translate the AT&T assembly code to Intel at some
point in the future. If the gcc x86 C compiler truly handle VC style
inlined assembly, including C identifiers within assembly code, then the
AT&T code can be entirely replaced. Otherwise separate AT&T and Intel
versions will need to be maintained. It has also been discussed to
reintroduce the original SSE versions of the routines. But this will
involve a rethink on how MMX/SSE support is provided.
