[Bug middle-end/45307] Stores expanding to no RTL not removed by tree optimizers, Empty ctors/dtors not eliminated

[jason at gcc dot gnu dot org]

------- Comment #11 from jason at gcc dot gnu dot org  2010-08-17 18:09 -------
There are two issues here:

1) expand_static_init decides whether a variable needs static initialization
before gimplification, and
2) Richard's MEM_REF-related change to cp_gimplify_expr caused us to stop
removing the copy in this example.

It sounds like if we fix #2 then the patch Honza mentions having should do the
trick.  I'll do that.
