obtained gcc-4.6.4.tar.bz2 from upstream website;upstream
verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.
downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.
if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

A function returns a class-wide object, +-- using the 'Class'Input attribute of the root type of the class to +-- extract the object from the stream. +-- A field-by-field comparison of record objects is performed to validate +-- the data read from the stream. Operator precedence rules are used +-- in the comparison rather than parentheses. +-- +-- APPLICABILITY CRITERIA: +-- This test is applicable to all implementations capable of supporting +-- external Stream_IO files. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 14 Nov 95 SAIC Corrected prefix of 'Tag attribute for ACVC 2.0.1. +-- 24 Aug 96 SAIC Changed a call to "Create" to "Reset". +-- 26 Feb 97 CTA.PWB Allowed for non-support of some IO operations. +--! + +with FXACC00, Ada.Streams.Stream_IO, Ada.Tags, Report; + +procedure CXACC01 is + + Order_File : Ada.Streams.Stream_IO.File_Type; + Order_Stream : Ada.Streams.Stream_IO.Stream_Access; + Order_Filename : constant String := + Report.Legal_File_Name ( Nam => "CXACC01" ); + Incomplete : exception; + +begin + + Report.Test ("CXACC01", "Check that the use of 'Class'Output " & + "and 'Class'Input allow stream manipulation " & + "of objects of non-limited class-wide types"); + + Test_for_Stream_IO_Support: + begin + + -- If an implementation does not support Stream_IO in a particular + -- environment, the exception Use_Error or Name_Error will be raised on + -- calls to various Stream_IO operations.
