sched-int.h (ds_t, dw_t): Make unsigned int.
* sched-int.h (ds_t, dw_t): Make unsigned int.
Fix documentation that describes how all the ds_t bits are used.
Reserve the last bit for delayed-branch scheduling.
(BITS_PER_DEP_STATUS): Move to ds_t typedef.
(BITS_PER_DEP_WEAK): Fix definition and documentation.
(gen_dep_weak_1): Remove prototype.
* sched-deps.c (get_dep_weak_1): Make static.
* target.def (speculate_insn, needs_block_p, gen_spec_check,
get_insn_spec_ds, get_insn_checked_ds): Adjust hook prototypes.
* doc/tm.texi: Regenerate.
* config/ia64/ia64.c (ia64_needs_block_p): Update prototype.
