Ada Programming/Pragmas
Description
[edit | edit source]Pragmas control the compiler, i.e. they are compiler directives. They have the standard form of
pragma Name (Parameter_List);
where the parameter list is optional.
List of language defined pragmas
[edit | edit source]Some pragmas are specially marked:
- Ada 2005
- This is a new Ada 2005 pragma.
- Ada 2012
- This is a new Ada 2012 pragma.
- Obsolescent
- This is a deprecated pragma and it should not be used in new code.

List of implementation defined pragmas
[edit | edit source]The following pragmas are not available in all Ada compilers, only in those that had implemented them.
Currently, there are only listed the implementation-defined pragmas of a few compilers. You can help Wikibooks adding specific aspects of other compilers:
- GNAT
- Implementation defined pragma of the GNAT compiler from AdaCore and FSF.
- HP Ada
- Implementation defined pragma of the HP Ada compiler (formerly known as "DEC Ada").
- ICC
- Implementation-defined pragma[1] of the Irvine ICC compiler.
- PowerAda
- Implementation defined pragma of OC Systems' PowerAda.
- SPARCompiler
- Implementation defined pragma of Sun's SPARCompiler Ada.[2]
