* basic-block.h (could_fall_through): Declare.
* cfganal.c (can_fallthru): Succeed if the target is EXIT_BLOCK_PTR.
Fail if the source already has a fallthrough edge to the exit
block pointer.
(could_fall_through): New function.
* cfgbuild.c (make_edges): Check if we already have a fallthrough
edge to the exit block pointer.
* cfglayout.c (fixup_fallthru_exit_predecessor): Check that it is
not called before reload has completed.
Handle special case of first block having a fall-through exit edge.
(cfg_layout_finalize): Don't call it before reload or if we have
rtl epilogues.
(fixup_reorder_chain): A fall through to the exit block does not
require the block to come last. Add sanity checks.
* cfgrtl.c (rtl_split_edge): Add special handling of fall through
edges to the exit block.
* function.c (cfglayout.h): #include.
(thread_prologue_and_epilogue_insns): If we have neither return nor
epilogue, but a fall through to the exit block from mid-function,
force a non-fall-through exit.
* Makefile.in (function.o): Depend on CFGLAYOUT_H.
