Simplification within reorg.c

[official-gcc.git] / gcc / ChangeLog

2014-09-05  David Malcolm  <dmalcolm@redhat.com>

        * reorg.c (relax_delay_slots): Move declaration of "trial_seq"
        above the conditional, and convert the check on GET_CODE to a
        dyn_cast, so that "trial_seq" is available as an rtx_sequence * in
        the conditional.  Simplify the conditional by using methods of
        "trial_seq".

2014-09-05  David Malcolm  <dmalcolm@redhat.com>

        * haifa-sched.c (check_clobbered_conditions): Strengthen local

        (restore_last_backtrack_point): Likewise.
        (queue_to_ready): Use insn method of "link" in one place.

        its methods for clarity and type-safety.
        (sched_analyze_1): Strengthen local "pending" from rtx to
        rtx_insn_list *, and local "pending_mem" from rtx to

        (sched_analyze_insn): Likewise.

        * sched-int.h (sched_get_reverse_condition_uncached): Strengthen

        (peephole2_optimize): Likewise for local "last".

2014-09-05  David Malcolm  <dmalcolm@redhat.com>

        * config/h8300/h8300.md (define_insn "jump"): Replace local rtx
        "vec" with an rtx_sequence * "seq", taking a copy of

        (output_insn_latency_func): When writing the function

        change to the generated "internal_insn_latency" function.
