Cool, I was thinking about adding both a C and an asm version, but it looks
like you already did it! =)
Now, can you make it to be a common API, so we can use the same code base
for all the windowed drivers? Or is it so tightly attached that this would
break the Win32 port?
Of course we'd need both asm and C versions, for non i386 platforms...
Having optimized asm routines (even with MMX support) would really benefit X
and BeOS drivers (not counting the upcoming QNX and maybe MacOS ones)!
