The <special-name> production.

The <special-name> production is spread in pieces through out the ABI spec, and then there are a bunch of g++ extensions that have become de facto.

5.1.4.1 Virtual Tables and RTTI

<special-name> ::= TV <type>    # virtual table
               ::= TT <type>    # VTT structure (construction vtable index)
               ::= TI <type>    # typeinfo structure
               ::= TS <type>    # typeinfo name (null-terminated byte string)

5.1.4.2 Virtual Override Thunks

<special-name> ::= T <call-offset> <base encoding>
    # base is the nominal target function of thunk

<special-name> ::= Tc <call-offset> <call-offset> <base encoding>
    # base is the nominal target function of thunk
    # first call-offset is 'this' adjustment
    # second call-offset is result adjustment

5.1.4.4 Guard Variables

<special-name> ::= GV <object name> # Guard variable for one-time initialization
    # No <type>

5.1.4.5 Lifetime-Extended Temporaries

<special-name> ::= GR <object name> _             # First temporary
<special-name> ::= GR <object name> <seq-id> _    # Subsequent temporaries

De Facto Standard Extensions

<special-name> ::= TC <type> <number> _ <type>    # construction vtable
               ::= TF <type>                      # typinfo function
               ::= TH <name>                      # TLS initialization function
               ::= TW <name>                      # TLS wrapper function
