ACATS Test Modification List

ACATS Test Modification List

Version 2.4G
January 22, 2002

Changes from the last list:

Test B3A2009 contains a check which conflicts with the under consideration AI-229. AI-229 allows 'Access for subprograms in generic bodies if the access type is declared in the generic's specification; the RM language does not. Because of the inconsistency, this subtest has been commented out (the ACAA would like to allow vendors to implement the AI, as it is necessary to prevent dangling references to subprograms).

Test CD72A02 has had the test description corrected (it referred to a non-existent test). No substantive changes were made to this test.

Reminder: ACATS 2.5 will be issued in March. As with ACATS 2.3 and 2.4 before it, this is simply a "roll-up" of tests modified before January 1, 2002 and new tests added before October 1, 2001; the same tests would be required on April 1, 2002 whether or not it is issued. The main advantage of new ACATS versions is that the documentation is updated to reflect changes from the past year.

New tests inserted between January 1, 2002 and April 1, 2002 will become required for conformity assessments on October 1, 2002. New tests inserted between October 1, 2001 and January 1, 2002 will become required for conformity assessments on July 1, 2002. New tests inserted between July 1, 2001 and October 1, 2001 will become required for conformity assessments on April 1, 2002. New tests added to the ACATS before July 1, 2001 are now required for conformity assessments. The effective dates of tests are marked in the lists.

List explanation:

Test numbers given are for the basic test. Categories are "Withdrawn" (the test should not be processed for Ada conformity assessments); "Allowed Modification" (either the original test or the modified one should be processed for Ada conformity assessments); "Modified" (the modified test must be processed for Ada conformity assessments); "Pending New" (the test does not need to be processed for Ada conformity assessments, but will be added in the future); "New" (the test is processed for Ada conformity assessments).

ACATS version labels are provided with all new and modified tests. Use this label to retrieve the test from the ACATS VCS. See "How to get new and modified tests".

In citations, line numbers are given relative to the start of a test file in the format of '@<line#,line#,...>'; if a test program comprises more than one file, then the particular file will be indicated by "fn", where "n" is the test-program name's file-designator numeral. E.g., "B38103E : @f1-31, ... " denotes test file

b38103e1.ada. In cases where there are two or more rationales for different errors in a test program, these different rationales with their respective line citations are listed on separate lines. References to the Ada 83 & Ada 95 standards are given in the format:

<section|chapter>.<clause>[.<subclause>]:<paragraph>

These references are to the Ada 95 standard unless "Ada83" is specified.

How to get new and modified tests:

The official home of the ACATS test suite is the ACAA web site. The site can be accessed from the Compilers and Conformance section of the Ada IC web site (www.adaic.org). It also can be accessed directly at www.ada-auth.org.

The complete set of official new and modified tests are available in the Mod_2_4G Zip and Tar files on the ACAA web site.

Individual new and modified tests can be retrieved from the ACATS VCS. Simply navigate to the appropriate directory (folder), and select the test you want. Select the revision you want (usually the most recent) and it will be retrieved for you. Tests are stored in directories that correspond to the test's prefix. For instance, the test CD92001.A will be found in the CD directory. You can also browse the differences between versions of a test. [In case of a conflict, the files in the ACATS VCS should be considered the 'official' versions.]

If you cannot get the files from the official site or you cannot get the files in a format appropriate for your processor, please contact your ACAL.

The baseline ACATS 2.4 is available in various formats on the ACAA web site.
