Subject: [Bug c/66090] Wrong loop code generation with -O2 on ARM
Date: Wed, 13 May 2015 15:20:00 -0000	[thread overview]
Message-ID: <bug-66090-4-E7ThWdSkcn@http.gcc.gnu.org/bugzilla/> (raw)
In-Reply-To: <bug-66090-4@http.gcc.gnu.org/bugzilla/>

--- Comment #6 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
I think this comes under tracking pointer provenance (DR#260) and saying 
that certain arithmetic on pointers derived by casts from integers has 
undefined behavior.
