[Bug tree-optimization/85301] bitfield check causes maybe-uninitialized warning


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85301

--- Comment #5 from Jeffrey A. Law <law at redhat dot com> ---
FWIW, there's another similar bug where DOM doesn't do a particularly good job
at tracking the state of objects implied the results of logical operations
which in turn causes missed optimizations.  I've poked at it a few times but
haven't come up with anything good to address the deficiency.  It's on the
Wuninitialized tracker, so I'll certainly take a look over the coming months.
