URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=131212
Log:
        * config/ia64/ia64.c (ia64_speculate_insn): Use ds_get_speculation_types
        when determining whether we need to change the pattern.
        * sched-int.h (LUID_BY_UID): New accessor macro.
        * sched-rgn.c (compute_block_dependences): Do not call add_branch_dependences
        for selective scheduling.
        (free_rgn_deps): Tidy.

        * sel-sched-ir.c (vinsn_attach, vinsn_detach): Export.
        (find_in_hash_vect{,_1}): Rename to find_in_history_vect{,_1}.
        Rewrite to use a history vector.
        (insert_in_hash_vect): Likewise.  Rename to insert_in_history_vect.
        (init_expr): Change CHANGED_ON parameter to be a history vector.
        Update all callers.
        (merge_expr_data): Update for history vectors.
        (clear_expr): Likewise.
        (free_first_time_insn_data): Handle INSN_ORIGINATORS.
        (is_ineligible_successor): Do not check the path for back edges.
        (bb_ends_ebb_p, clear_outdated_rtx_info): Tidy.

        * sel-sched-ir.h (enum local_trans_type): New.
        (struct expr_history_def_1, expr_history_def): New.
        (struct _expr): Rename changed_on_insns vector to history_of_changes.
        Make it of expr_history_def type.
        (EXPR_CHANGED_ON_INSNS): Rename to EXPR_HISTORY_OF_CHANGES.
        (struct _sel_insn_data): Fix comments.  New field originators.
        (SID_BY_UID, INSN_ORIGINATORS, INSN_ORIGINATORS_BY_UID): New accessor
        macros.

        * sel-sched.c (un_substitute): Mark as unused.
        (apply_spec_to_expr): Inline to ...
        (speculate_expr): ... here.  Change return value to int.
        Do not copy a pattern when no changes were made.
        (un_speculate): Mark as unused.
        (undo_transformations): Perform unspeculation and unsubstitution
        by looking into the history vector.
        (moveup_rhs): Add PTRANS_TYPE parameter, adjust all callers.  Return
        the type of transformation being done.  Assert that we don't do
        speculation and substitution on the same insn.
        (moveup_set_rhs): Record the performed transformation into the history
        vector of an expression.
        (current_copies, current_originators): New static variables.
        (generate_bookkeeping_insn): Record the generated insn in
        current_copies.  Always set SCHED_TIMES of a bookkeeping insn to 0.
        (fill_insns): Clear current_* bitmaps before move_op.
        When some bookkeeping insns were generated, allocate INSN_ORIGINATORS
        for them and set it to the copy of current_originators.
        (move_op): Add dest parameter.  Pass it explicitly instead of
        calculating from original operations.  When an original insn was
        found, adjust current_copies and current_originators accordingly.
        (sel_region_init): Initialize current_* bitmaps.
        (sel_region_finish): Free them.
