anyone more experienced with the code. Check out for examples the r128
driver from the trunk, for a good example. Notice there are files in there
such as r128_tritmp.h. This is a template that gets included in r128_tris.c.
What it does basically is consolidate code that is largly reproduced over
several functions, so that you set a few macros. For example:
#define IND (R128_TWOSIDE_BIT)
#define TAG(x) x##_twoside
followed by
#include "r128_tritmp.h"
Notice the inline function's name defined in r128_tritmp.h is the result of
the TAG macro, as well the function's content is dependant on what IND value
is defined. So essentially the inline function is a template for various
functions that have a bit in common. That way you consolidate common code
and keep things consistent.
The current mach64 branch is only using one template in the driver. But yes,
it does have some of the driver template code there.
