New Revision: 132752

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=132752
Log:
        * sel-sched-dump.c (dump_expr_1): Print correct value of
        EXPR_TARGET_AVAILABLE.
        * sel-sched-ir.h (struct vinsn_def): New field hash_rtx.
        (VINSN_HASH_RTX): New accessor.
        (struct transformed_insns): New.
        (struct _sel_insn_data): New field transformed_insns.
        (INSN_TRANSFORMED_INSNS): New accessor.
        * sel-sched-ir.c (vinsn_init): Initialize VINSN_HASH_RTX.
        (vinsn_delete): Kill outdated comment.
        (speculate_expr): Return 2 when we think that the target
        register is unavailable for speculation.
        (hash_transformed_insns, eq_transformed_insns,
        free_transformed_insns): New.
        (init_first_time_insn_data): Init INSN_TRANSFORMED_INSNS.
        (free_first_time_insn_data): Free INSN_TRANSFORMED_INSNS.
        (finish_insns): Likewise.
        (finish_global_and_expr_insn): Do not assert that the vinsn
        is connected only to one insn.
        * sel-sched.c (undo_transformations): Also undo when only
        a dependence status has changed, not insn's pattern.
        Update comment.
        (was_target_conflict): New static variable.
        (moveup_rhs): Set it when a target conflict is encountered.
        (moveup_set_rhs): When an expression is changed, record this
        in INSN_TRANSFORMED_INSNS.  Lookup this hashtable before calling
        moveup_rhs.  Use was_target_conflict when recording.
