Expand description

The <ctor-dtor-name> production.

<ctor-dtor-name> ::= C1  # complete object constructor
                 ::= C2  # base object constructor
                 ::= C3  # complete object allocating constructor
                 ::= D0  # deleting destructor
                 ::= D1  # complete object destructor
                 ::= D2  # base object destructor

GCC also emits a C4 constructor under some conditions when building an optimized binary. GCC’s source says:

/* This is the old-style "[unified]" constructor.
   In some cases, we may emit this function and call
   it from the clones in order to share code and save space.  */

Based on the GCC source we’ll call this the “maybe in-charge constructor”. Similarly, there is a D4 destructor, the “maybe in-charge destructor”.
