* sched-deps.c (sched_get_condition): Enable #if 0'ed code.
(sched_insns_conditions_mutex_p): Split out from...
(add_dependence): ...here. But don't call it from here.
(add_dependence_list): Check sched_insns_conditions_mutex_p
before calling add_dependence.
(add_dependence_list_and_free): Likewise.
(fixup_sched_groups): Likewise.
(sched_analyze_1): Likewise.
(sched_analyze_2): Likewise (and replace a "0" with REG_DEP_TRUE).
(sched_analyze): Likewise.
(sched_analyze_insn): Likewise.
* sched-ebb.c (add_deps_for_risky_insns): Likewise.
* sched-rgn.c (add_branch_dependences): Likewise. Also, add
dependencies on all COND_EXEC insns to jumps ending basic blocks
when doing intrablock scheduling.
* sched-int.h (sched_insns_conditions_mutex_p): Add prototype.
