Let's eliminate duplicate definitions by aliasing ALIGN_UP to ALIGN. #define ALIGN_UP(a, b) ALIGN(a, b) There's also a macro to do ALIGN_DOWN, which is called ROUND_DOWN_TO(). Note that the existing ALIGN() and ROUND_DOWN_TO() macros only work when b is a power of two.
In this patch, b is always a power-of-two. So no problem. _______________________________________________ mesa-dev mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-dev
