-/* A bit of a glossary:
- *
- * brw_wm_value: A computed value or program input. Values are
- * constant, they are created once and are never modified. When a
- * fragment program register is written or overwritten, new values are
- * created fresh, preserving the rule that values are constant.
- *
- * brw_wm_ref: A reference to a value. Wherever a value used is by an
- * instruction or as a program output, that is tracked with an
- * instance of this struct. All references to a value occur after it
- * is created. After the last reference, a value is dead and can be
- * discarded.
- *
- * brw_wm_grf: Represents a physical hardware register. May be either
- * empty or hold a value. Register allocation is the process of
- * assigning values to grf registers. This occurs in pass2 and the
- * brw_wm_grf struct is not used before that.
- *
- * Fragment program registers: These are time-varying constructs that
- * are hard to reason about and which we translate away in pass0. A
- * single fragment program register element (eg. temp[0].x) will be
- * translated to one or more brw_wm_value structs, one for each time
- * that temp[0].x is written to during the program.
