History

Duncan Sands b8f3b14dfb If a function does a volatile load from a global constant, do not

consider it to be readonly.  In fact, don't even consider it to be
readonly if it does a volatile load from an AllocaInst either (it
is debatable as to whether readonly would be correct or not in this
case; play safe for the moment).  This fixes PR8279.
