- Subject: patch that FIXED regression PR opt/7247 (still broken in 3.2 branch)
PR optimization/7247 is for a regression that was fixed in the mainline
before the 3.3-branch was created and still exists in the 3.2 branch.
It was fixed on the mainline with this patch:

Daniel Berlin <dan@dberlin.org>
* cp-lang.c (ok_to_generate_alias_set_for_type): New function.
(cxx_get_alias_set): Use it.

C++ alias analysis improvement.
* alias.c (record_component_aliases): Record aliases for base
classes too.
For my search I used the reduced test case in the PR with the
optimizations shown there. This information has been added to GNATS.
