36 * This file contains definitions for various T4 register value hardware
37 * constants. The types of values encoded here are predominantly those for
38 * register fields which control "modal" behavior. For the most part, we do
39 * not include definitions for register fields which are simple numeric
42 * These new "modal values" use a naming convention which matches the
43 * currently existing macros in t4_reg.h. For register field FOO which would
44 * have S_FOO, M_FOO, V_FOO() and G_FOO() macros, we introduce X_FOO_{MODE}
45 * definitions. These can be used as V_FOO(X_FOO_MODE) or as (G_FOO(x) ==
48 * Note that this should all be part of t4_regs.h but the toolset used to
49 * generate that file doesn't [yet] have the capability of collecting these
59 * SGE register field values.
