Re: [Mesa3d-dev] X renderer speedup (write_span_mono_pixmap optimization)

[Keith W. <ke...@va...>]

How about this as a cleaner (untested) version of the loop:

      for (i = 0 ; i < n ;) {
	 GLuint start = i;

	 /* Identify and emit contiguous rendered pixels 
	  */
	 for( ; i < n && mask[i]; i++)
	    ;

	 if (start < i) 
	    XMesaFillRectangle( dpy, buffer, gc, 
				(int)(x+start), (int) y, 
				(int)(i-start), 1);

	 /* Eat up non-rendered pixels
	  */
	 for( ; i < n && !mask[i]; i++)
	    ;
      }
