I have one question (might be a stupid question):

Should we consider a call to C++’s constructor as the initialization to that 
variable?

For example:

S::S (&s);

Should we consider the above as an initialization to the variable s?
then -ftrivial-auto-var-init should NOT insert the DEFFRRED_INIT to s?

The constructor might not fully initialize the variable, so I would keep 
the DEFERRED_INIT.
