New Revision: 125913

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=125913
Log:
        * cse.c (hash_rtx_string): Export.
        * sel-sched.c (struct hard_regs_data): New struct.
        (sel_all_regs): Rename to regs_ever_used, change to HARD_REG_SET
        and move to the above struct.  Update all uses.
        (sel_hrd): New global variable.
        (init_hard_regno_rename, sel_hard_regno_rename_ok,
        init_regs_for_mode, init_hard_regs_data): New functions.
        (mark_unavailable_hard_regs): Move some code to the above
        functions and use them.  Return early when a destination
        is not a register.  Move code dealing with frame pointers
        from ...
        (choose_best_reg_1): ... here.
        (find_best_reg_for_rhs): Tidy comment.
        (undo_transformations): Fix comment.  Use hashes instead of bitmaps
        to determine whether an expr was changed on this insns.
        (moveup_set_rhs): Likewise.
        (sel_global_init): Call init_hard_regs_data.
        * sel-sched-ir.c (sel_hash_rtx): New static function.  Adopt from
        hash_rtx, tidy.  Leave only necessary comments.
        (vinsn_init): Use it.
        (find_in_hash_vect_1, find_in_hash_vect, insert_in_hash_vect): New
        functions.
        (vinsns_correlate_as_rhses_p): Use vinsn hashes.
        (init_expr, copy_expr, merge_expr_data, clear_expr): Update to use
        hash vectors instead of bitmaps.
        (sel_bb_head): Check for head being NULL before using it.
        (sel_add_or_remove_bb): Disable too expensive check.
        * sel-sched-ir.h: Include vecprim.h.
        (struct _expr): Change the type of change_on_insns field to a vector.
        (struct vinsn_def): New field hash.
        (VINSN_HASH): New accessor macro.
        (find_in_hash_vect, insert_in_hash_vect): Declare.
        * rtl.h (hash_rtx_string): Declare.
        * vecprim.h: Define a vector type for unsigned values.
