Still a problem in latest 4.7, google/4.7, and trunk (4.8).
So 4.6 was working but 4.7 isn't?

No.
4.6 doesn't devirt (at -O2 or -O3) and therefore the DCE isn't relevant.
At both -O2 and -O3, with and without -fwhole-program, both with and

Now that 4.7 stage 1 is open, let me know if there's anything else I can
reasonably provide to provide examples, testing, etc. Thanks!

GCC 4.6.0.20101116 still shows this problem, but also introduces new problems

Let me know when this is implemented on trunk (preferrably by marking this

Note that testcase mises static in front of one/two. This is something I
plan to implement for next release. Last release has some preparation work for
it, but at the moment we don't really build may edges nor
