-- Generated Names --
---------------------
-- This section lists the various cases of generated names which are
-- built from existing names by adding unique leading and/or trailing
-- upper case letters. In some cases these names are built recursively,
-- in particular names built from types may be built from types which
-- themselves have generated names. In this list, xxx represents an
-- existing name to which identifying letters are prepended or appended,
-- and a trailing n represents a serial number in an external name that
-- has some semantic significance (e.g. the n'th index type of an array).
-- xxxA access type for formal xxx in entry param record (Exp_Ch9)
-- xxxB tag table for tagged type xxx (Exp_Ch3)
-- xxxB task body procedure for task xxx (Exp_Ch9)
-- xxxD dispatch table for tagged type xxx (Exp_Ch3)
-- xxxD discriminal for discriminant xxx (Sem_Ch3)
-- xxxDn n'th discr check function for rec type xxx (Exp_Ch3)
-- xxxE elaboration boolean flag for task xxx (Exp_Ch9)
-- xxxE dispatch table pointer type for tagged type xxx (Exp_Ch3)
-- xxxE parameters for accept body for entry xxx (Exp_Ch9)
-- xxxFn n'th primitive of a tagged type (named xxx) (Exp_Ch3)
-- xxxI initialization procedure for type xxx (Exp_Ch3)
-- xxxJ tag table type index for tagged type xxx (Exp_Ch3)
-- xxxM master Id value for access type xxx (Exp_Ch3)
-- xxxP tag table pointer type for tagged type xxx (Exp_Ch3)
-- xxxP parameter record type for entry xxx (Exp_Ch9)
-- xxxPA access to parameter record type for entry xxx (Exp_Ch9)
-- xxxPn pointer type for n'th primitive of tagged type xxx (Exp_Ch3)
-- xxxR dispatch table pointer for tagged type xxx (Exp_Ch3)
-- xxxT tag table type for tagged type xxx (Exp_Ch3)
-- xxxT literal table for enumeration type xxx (Sem_Ch3)
-- xxxV type for task value record for task xxx (Exp_Ch9)
-- xxxX entry index constant (Exp_Ch9)
-- xxxY dispatch table type for tagged type xxx (Exp_Ch3)
