Re: [ros-dev] [ros-diffs] [tkreuzer] 42353: asm version of DIB_32BPP_ColorFill: - Add frame pointer - Get rid of algin_draw, 32bpp surfaces must be DWORD aligned - Optimize the loop - Add comments

A correction of my previous msg:

In asm I would write the loop as:
	mov eax, iColor	
	mov ebx, pulLine
	mov edx, cy
L1:
	mov edi, ebx
	mov ecx, _cx
	rep stosd
	add ebx, lDelta
	dec edx
	jnz l1

It is not possible to optimize the loop further AFAIK, and this only saves a
cmp and jnz in the outer loop, a tiny gain.
