ModRefInfo getModRefInfoForGlobal (const GlobalValue &GV) const
Returns the ModRefInfo info for this function w.r.t.
void addFunctionInfo (const FunctionInfo &FI)
Add mod/ref info from another function into ours, saturating towards ModRef.

void eraseModRefInfoForGlobal (const GlobalValue &GV)
Clear a global's ModRef info.

The mod/ref information collected for a particular function.

We collect information about mod/ref behavior of a function here, both in general and as pertains to specific globals. We only have this detailed information when we know something useful about the behavior. If we saturate to fully general mod/ref, we remove the info for the function.
