--- Comment #3 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Thanks.

I was seeing:
  real  1m31.214s

Adding a cache to region_model::get_initial_value_for_global speeds things =
up
greatly to:
  real  0m3.677s

Adding a further cache to decl_region::get_svalue_for_constructor gives a
further slight speedup to:
  real  0m3.069s

I'm working on a fix based on the above.=
