URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=135816
Log:
        * tree-pass.h (pass_sel_sched): Remove.
        * sel-sched.c (maybe_skip_selective_scheduling): New.  Export it.
        (gate_handle_sel_sched, handle_sel_sched, pass_sel_sched): Remove.
        (debug_state): New.
        (advance_one_cycle, advance_state_on_fence): Use it.
        (extract_new_fences_from): Fix formatting.
        (can_substitute_through_p): Disallow substitutions through CONST_INTs.
        (estimate_insn_cost): New, factored from ...
        (vinsn_dfa_cost): ... here.  Renamed to get_expr_cost.
        (choose_best_insn): When max_issue is not used, try to select
        the first available insn from the ready list.  Correctly set can_issue.
        (stall_for_cycles): When stalling for more than one cycle, always
        set FENCE_AFTER_STALL_P.
        (track_scheduled_insns_and_blocks): Always add found insns to
        current_originators.
        (reset_sched_cycles_in_current_ebb): New variables real_insn,
        after_stall.  Use estimate_insn_cost.  Handle the corner case when
        state_transition seems to be lying about the cost.
        * sel-sched-ir.c (state_create): Always start from advanced state.
        (deps_init_id_note_reg_set): When stack registers are used,
        make the instruction of type use to avoid renaming.
        (maybe_downgrade_id_to_use): Likewise.  Downgrade only SETs.
        (setup_id_reg_sets): Treat writes/reads to/from stack registers
        as corresponding action with the first stack reg.
        (has_dependence_p): Also punt for MOVE_BARRIER.
        * sched-rgn.c (rest_of_handle_sched, rest_of_handle_sched2): Run
        selective scheduling if requested.
        * passes.c (init_optimization_passes): Remove mentions of pass_sel_sched.
        * config/i386/i386.c (override_options): Turn on selective scheduling
        with -O2 for testing purposes.
        * config/ia64/ia64.c (ia64_reorg): Remove debug handling of selective
        scheduling.
