When built with gcc 4.6, the MMX rgb24 to yuv conversion gives
wrong output. The compiler produces this warning:
libswscale/swscale_template.c:1885:5: warning: use of memory input without lvalue in asm operand 4 is deprecated
Changing the memory operand to a register makes it work.
Signed-off-by: Mans Rullgard <mans@mansr.com>
(cherry picked from commit f344903ca5)
Don't change paramater passing, but instead use casts.
Shouldn't affect asm output on anything other than win64.
libswscale should work on win64 now.
The rest of ffmpeg still isn't win64 compatible due to the issue of xmm
clobbers, but swscale doesn't use any SSE.

long was being incorrectly used as an x86-sized register, both for 32 and 64
bits, but this is not the case in win64.

This is of course done with permissions from the authors. The only GPL
component left are MMX optimizations for YUV to RGB conversion.

These index variables are incremented before each use, so they should be
initialized to -1.

All functions in swscale_template.c should be declared with the RENAME macro.
