re PR rtl-optimization/40445 (g++ void f() { __builtin_unreachable(); })
2009-07-25 David Daney <ddaney@caviumnetworks.com>
PR rtl-optimization/40445
* emit-rtl.c (next_nonnote_insn_bb): New function.
* rtl.h (next_nonnote_insn_bb): Declare new function.
* cfgcleanup.c (try_optimize_cfg): Don't remove an empty block
with no successors that is the successor of the ENTRY_BLOCK.
Continue from the top after removing an empty fallthrough block.
* cfgrtl.c (get_last_bb_insn): Call next_nonnote_insn_bb instead
of next_nonnote_insn.
