Subject: haifa-sched.c (move_insn): Reemit notes for SCHED_GROUP_P insns too.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4f64eacaeec81753d30ecb684ec8f3ba2f3b9f7b;p=platform%2Fupstream%2Fgcc.git

haifa-sched.c (move_insn): Reemit notes for SCHED_GROUP_P insns too.

        * haifa-sched.c (move_insn): Reemit notes for SCHED_GROUP_P
        insns too.
        (schedule_block): When adjusting basic_block_{head,end}, account
        for movement of SCHED_GROUP_P insns too.

        * haifa-sched.c (debug_dependencies): Fix thinko.
