* config/spu/spu.c: Include "cfgloop.h".
(spu_machine_dependent_reorg): Call loop_optimizer_init and loop_optimizer_finalize. Use bb_loop_depth instead of loop_depth. Directly compare loop_father values where appropriate. * config/spu/t-spu-elf (spu.o): Update dependencies. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@190421 138bc75d-0d04-0410-961f-82ee72b054a4
