[PATCH 087/236] loop-doloop.c: Use rtx_insn in a few places

[David Malcolm]

gcc/
        * loop-doloop.c (doloop_valid_p): Strengthen local "insn" from rtx
        to rtx_insn *.
        (add_test): Likewise for locals "seq", "jump".
        (doloop_modify): Likewise for locals "sequence", "jump_insn".
