--- Comment #1 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Benchmarking build with -O3 -flto -Ofast -funroll-loops

For mainline I get (running on  input.graphic)

real    0m35.673s
user    0m35.556s
sys     0m0.133s

and setting early-inlining-insns=80 to get bsR/bsW inlined before we get LTO

real    0m31.975s
user    0m31.867s
sys     0m0.124s

-fno-ipa-cp:

real    0m34.232s
user    0m34.132s
sys     0m0.117s


For GCC 4.9 I get.

real    0m32.719s
user    0m32.615s
sys     0m0.124s

Oddly enought GCC 4.9 does not inlie bsR/bsW either.
