The competition has three prizes of $2,000 each!

Just came across a donation site for the Alire project.

Contributing to the Ada open source ecosystem through the Alire package manager for Ada/SPARK

Online participation in the Ada Developers Workshop will be free of charge! It is still a requirement to register. As a reminder, the Workshop's programe has been available for a while, so go ahead an take a look! 🤩

GNAT FSF 14 is now available in a special index branch. Use this command to add the index branch:

alr index "--add=git+https://github.com/alire-project/alire-index#gnat-fsf-14.1" --name=gnat_fsf_14 --before=community

And then alr index --del=gnat_fsf_14 to remove it once your done playing with it.

If you have some time to give it a try and give me some feedback that would be great 👍️

The list of presentations looks great!

• New implementation-defined aspects and pragmas:
  • Local_Restrictions, which specifies that a particular subprogram does not violate one or more local restrictions, nor can it call a subprogram that is not subject to the same requirements.
  • User_Aspect_Definition and User_Aspect, which provide a mechanism for avoiding textual duplication if some set of aspect specifications is needed in multiple places.
• New implementation-defined aspects and pragmas for verification of the SPARK 2014 subset of Ada:
  • Always_Terminates, which provides a condition for a subprogram to necessarily complete (either return normally or raise an exception).
  • Ghost_Predicate, which introduces a subtype predicate that can reference Ghost entities.
  • Exceptional_Cases, which lists exceptions that might be propagated by the subprogram with side effects in the context of its precondition and associates them with a specific postcondition.
  • Side_Effects, which indicates that a function should be handled like a procedure with respect to parameter modes, Global contract, exceptional contract and termination: it may have output parameters, write global variables, raise exceptions and not terminate.
• The new attributes and contracts have been applied to the relevant parts of the Ada runtime library, which has been subsequently proven to be correct with SPARK 2014.
• Support for the LoongArch architecture.
• Support for vxWorks 7 Cert RTP has been removed.
• Additional hardening improvements. For more information reltated to hardening options, refer to the GCC Instrumentation Options and the GNAT Reference Manual, Security and Hardening Features.
• Improve style checking for redundant parentheses with -gnatyz
• New switch -gnateH to force reverse Bit_Order threshold to 64.
• Experimental features:
  • Storage Model: this feature proposes to redesign the concepts of Storage Pools into a more efficient model allowing higher performances and easier integration with low footprint embedded run-times.
  • String Interpolation: allows for easier string formatting. Further clean up and improvements to the GNAT code.
