--- Comment #8 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
OK, the unmangled name of symbol is:
000000000004c8c0 T
_ZN4llvm21SymbolTableListTraitsINS_10BasicBlockENS_8FunctionEE21transferNodesFromListERNS_12ilist_traitsIS1_EENS_14ilist_iteratorIS1_EES8_

and obviously for me it is T for -O2 and for -O3 it is optimized out.  Both
seems legitimate. Can you please re-check with current mainline?

I get:
 df live regs            :   7.74 (12%) usr   0.00 ( 0%) sys   7.72 (12%) wall 
     0 kB ( 0%) ggc
 df live&initialized regs:  11.02 (17%) usr   0.00 ( 0%) sys  10.91 (17%) wall 
     0 kB ( 0%) ggc
 CPROP                   :  20.03 (32%) usr   0.44 (65%) sys  20.51 (32%) wall 
  7968 kB ( 5%) ggc

(with checking on, but still seems something for steve, I do not think there is
particularly expensive checking in CPROP)

I am re-checking with 4.8
