package Snames is

--  This package contains definitions of standard names (i.e. entries in the
--  Names table) that are used throughout the GNAT compiler). It also contains
--  the definitions of some enumeration types whose definitions are tied to
--  the order of these preset names.

--  WARNING: There is a C file, a-snames.h which duplicates some of the
--  definitions in this file and must be kept properly synchronized.

   ------------------
   -- Preset Names --
   ------------------

   --  The following are preset entries in the names table, which are
   --  entered at the start of every compilation for easy access. Note
   --  that the order of initialization of these names in the body must
   --  be coordinated with the order of names in this table.

   --  Note: a name may not appear more than once in the following list.
   --  If additional pragmas or attributes are introduced which might
   --  otherwise cause a duplicate, then list it only once in this table,
   --  and adjust the definition of the functions for testing for pragma
   --  names and attribute names, and returning their ID values. Of course
   --  everything is simpler if no such duplications occur!

   --  First we have the one character names used to optimize the lookup
   --  process for one character identifiers (to avoid the hashing in this
   --  case) There are a full 256 of these, but only the entries for lower
   --  case and upper case letters have identifiers

   --  The lower case letter entries are used for one character identifiers
   --  appearing in the source, for example in pragma Interface (C).
