+--
+-- OBJECTIVE
+--     Check pragma Reviewable.
+--     Check that pragma Reviewable is accepted as a configuration pragma.
+--
+-- TEST DESCRIPTION
+--     The test requires that the configuration pragma Reviewable
+--     be processed.  The following package contains a simple "one of each
+--     construct in the language" to check that the configuration pragma has
+--     not disallowed some feature of the language.  This test should generate
+--     no errors.
+--
+-- APPLICABILITY CRITERIA:
+--      This test is only applicable for a compiler attempting validation
+--      for the Safety and Security Annex.
+--
+-- PASS/FAIL CRITERIA:
+--      This test passes if it correctly compiles, executes, and reports PASS.
+--      It fails if the pragma is rejected.  The effect of the pragma should
+--      be to produce a listing with information, including warnings, as
+--      required in H.3.1. Specific form and contents of this listing are not
+--      required by this test and are not part of the PASS/FAIL criteria.
+--
+-- SPECIAL REQUIREMENTS
+--      The implementation must process a configuration pragma which is not
+--      part of any Compilation Unit; the method employed is implementation
+--      defined.
+--
+--      Pragma Reviewable requires that the implementation provide the
+--      following information for the compilation units in this test:
+--
+--        o Where compiler-generated run-time checks remain (6)
+--
+--        o Identification of any construct with a language-defined check
+--          that is recognized prior to runtime as certain to fail if
+--          executed (7)
+--
+--        o For each reference to a scalar object, an identification of
+--          the reference as either "known to be initialized,"
+--          or "possibly uninitialized" (8)
+--
+--        o Where run-time support routines are implicitly invoked (9)
+--
+--        o An object code listing including: (10)
+--
+--          o Machine instructions with relative offsets (11)
+--
+--          o Where each data object is stored during its lifetime (12)
+--
+--          o Correspondence with the source program (13)
+--
+--        o Identification of each construct for which the implementation
+--          detects the possibility of erroneous execution (14)
+--
+--        o For each subprogram, block, task or other construct implemented by
+--          reserving and subsequently freezing an area of the run-time stack,
+--          an identification of the length of the fixed-size portion of
+--          the area and an indication of whether the non-fixed size portion
+--          is reserved on the stack or in a dynamically managed storage
+--          region (15)
+--
+--
+-- CHANGE HISTORY:
+--      26 OCT 95   SAIC   Initial version
+--      12 NOV 96   SAIC   Revised for 2.1
+--      27 AUG 99   RLB    Removed result dependence on uninitialized object.
+--      30 AUG 99   RLB    Repaired the above.
