Jelleke: Add section about Ada 83 compatibility in GNAT and remove some unnecessary stuff

'''GNAT''' is a free software compiler for Ada which forms part of the GNU Compiler Collection (GCC). It supports all versions of the language, i.e. Ada 2012, Ada 2005, Ada 95 and Ada 83. Originally its name was an acronym that stood for '''''G'''NU '''N'''YU '''A'''da '''T'''ranslator'', but that name no longer applies. The front-end and run-time are written in Ada.

== History ==

The GNAT project started in 1992 when the United States Air Force awarded New York University (NYU) a contract to build a free software compiler for Ada to help with the Ada 9X standardization process. The 3-million-dollar contract required the use of the GNU General Public License for all development, and assigned the copyright to the Free Software Foundation. The first official validation of GNAT occurred in 1995.

GNAT was initially released separately from the main GCC sources. On October 2, 2001, the GNAT sources were contributed to the GCC Concurrent Versions System repository.<ref>[https://gcc.gnu.org/ml/gcc-cvs/2001-10/msg00028.html GCC CVS mailing list archive] "New language: Ada"</ref> The last version to be released separately was GNAT 3.15p, based on GCC 2.8.1, on October 2, 2002. Starting with GCC 3.4, on major platforms the official GCC release is able to pass 100% of the [[Ada Conformity Assessment Test Suite|ACATS]] Ada tests included in the GCC testsuite. By GCC 4.0, more exotic platforms were also able to pass 100% of the ACATS tests.

== Compatibility with Ada 83 ==
GNAT was developed with Ada 9x in mind. However Ada has pretty good backwards compatibility so often times you'll find that Ada 83 code can compile fine on newer compilers. If you want to disallow any newer language features from Ada 95 and upwards however, you can tease GNAT into an Ada 83 compatibility mode. To do this you can pass the '''-gnat83''' switch to GCC<ref>[https://gcc.gnu.org/onlinedocs/gcc-4.8.5/gnat_ugn_unw/Compiling-Different-Versions-of-Ada.html] Ada 83 compatibility mode with the '''-gnat83''' switch in GNAT</ref>.

== License ==

The compiler is licensed under the terms of the GNU General Public License Version 3 with GCC Runtime Library Exception.

All versions leading up to and including 3.15p are licensed under the GMGPL offering similar runtime exceptions. The GMGPL license is GNU GPL 2 with a linking exception that permits software with licenses that are incompatible with the GPL to be linked with the output of Ada standard generic libraries that are supplied with GNAT without breaching the license agreement.

== Versions ==

[https://getadanow.com/ FSF GNAT] is part of most major Linux or BSD distributions and is included in the main GCC Sources.

GNAT Pro is a supported version of GNAT from AdaCore.

==Motivations==

This site aims to preserve heritage elements of the original Ada® language (now called '''Ada 83''').

'''Ada 83''' is a computer programming language set in its standard in 1983, and for which a fairly formidable design effort was deployed over nearly a decade, following which the language in its original form was used in large-scale projects over the following decade. Then revisions of the language were made which certainly increased its possibilities, but at the heavy cost of rather considerable complications on an originally quite sophisticated base which proved sufficient for many applications.

At the time of its availability, '''Ada 83''' was considered a “big” language, the compilation of which put contemporary machines to the test. On current systems in these 2020s, the compilation of '''Ada 83''' has become easy.

The extraordinary qualities of this language are, despite its age, still of particular interest from the point of view of software engineering. Since the operating principles of digital machines have not changed so much, the '''Ada 83''' language is still perfectly usable
and capable of providing services. Despite Ada 83's seemingly old age it is predated by other languages like C<ref>[https://en.wikipedia.org/wiki/C_(programming_language)] C programming language</ref> and <ref>[https://en.wikipedia.org/wiki/Pascal_(programming_language)] Pascal programming language</ref> Pascal that are still in use today.

At the very least, it is essential to preserve '''Ada 83''', its resources, its conceptual atmosphere, these works of human genius in the field of digital
information processing.

This site is thus a place dedicated to the [[Documentation|ANSI/MIL-STD-1815A-1983]] version of the Ada computer programming language ; version known today as '''Ada 83''' to distinguish it from later versions (Ada 95, Ada 2005, Ada 2012, Ada 2022).

The [[documentation|specification]] of '''Ada 83''' (the Ada Language Reference Manual) is close to 170 paper sheets long (around 270 pages of language definition proper), which makes it integrally accessible to an individual reader.

The Ada language still exists but evolved so much that we wanted to preserve elements of the original version of the language. '''Ada 83''' is a peculiar programming universe that really deserves preservation, both for computer history purpose and as an example of a specially well designed tool for software reliability, readability, maintenance. We believe that '''Ada 83''' is still useful forty years later.

==Purpose==

This site aims at gathering :

* '''[[Ada_83_history|history]]''' facts
* '''[[Ada_83_tools|tools]]'''
* '''[[documentation]]'''
* '''[[Ada_83_examples|examples]]''' written in '''Ada 83'''.

The interest is also about '''Ada 83''' language machines like the [[Rational_R1000_Ada83_machine|Rational R1000]] and the [[iAPX_432_Ada83_machine|iAPX 432]].

==Participate==

Feel free to participate to the elaboration of Ada 83 Memory whether you are a veteran of the 1980ies or a programming history enthusiast. Nonetheless be aware that only '''Ada 83''' is of interest here, no Ada 95 or later version will be considered (or only marginally if it serves an analytical purpose).

'''GNAT''' is a free software compiler for Ada which forms part of the GNU Compiler Collection (GCC). It supports all versions of the language, i.e. Ada 2012, Ada 2005, Ada 95 and Ada 83.

The extraordinary qualities of this language are, despite its forty-one-year-old age in 2024, still of particular interest from the point of view of software engineering. Since the operating principles of digital machines have not changed so much, the '''Ada 83''' language is still perfectly usable
and capable of providing services. Pascal, which predates it, is still used (albeit with object extensions), and the C language, whose contribution to
software engineering cannot be considered positively transcendent, is also.

At the very least, it is essential to preserve '''Ada 83''', its resources, its conceptual atmosphere, these works of human genius in the field of digital
information processing.

This site is thus a place dedicated to the ANSI/MIL-STD-1815A-1983 version of the Ada computer programming language ; version known today as '''Ada 83''' to distinguish it from later versions (Ada 95, Ada 2005, Ada 2012).

The specification of '''Ada 83''' (the Ada Language Reference Manual) is around 175 pages long, which makes it accessible to an individual.

The Ada language still exists but evolved so much that we wanted to preserve elements of the original version of the language. '''Ada 83''' is a peculiar programming universe that really deserves preservation, both for computer history purpose and as an example of a specially well designed tool for software reliability, readability, maintenance. We believe that '''Ada 83''' is still useful forty years later.

This site aims at gathering [[Ada_83_history|history]] facts and [[Ada_83_tools|tools]] or [[Ada_83_examples|examples]] written in '''Ada 83'''.

Feel free to participate to the elaboration of Ada 83 Memory if you are a veteran of the 1980ies . Nonetheless be aware that only '''Ada 83''' is of interest here, no Ada 95 or later version will be considered (or only marginally if it serves an analytical purpose).

This site aims to preserve heritage elements of the original Ada® language (now called '''Ada 83''').

'''Ada 83''' is a computer programming language set in its standard in 1983, and for which a fairly formidable design effort was deployed over nearly a decade, following which the language in its original form was used in large-scale projects over the following decade. Then revisions of the language were made which certainly increased its possibilities, but at the heavy cost of rather considerable complications on an originally quite sophisticated base which proved sufficient for many applications.

At the time of its availability, '''Ada 83''' was considered a “big” language, the compilation of which put contemporary machines to the test. On current systems in these 2020s, the compilation of '''Ada 83''' has become easy.
