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.

   --  NOTE WELL: If you add names of attributes, the enumeration type
   --  Attribute_Id must be kept in synch (same names in same order, with
   --  some exceptions). See the body of Get_Attribute_Id for details. The
   --  same is true of other enumeration types declared in this package.

   ------------------
   -- 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).
