Arnaud has volunteered to be the "supervisor". So here is my plan: crowdsourcing! :D I would like to write a (simple) list of changes for each version here, on the CLA. If you want to add something __copy__ (do not quote) the list from the previous person/reply/modification and add your proposed changes. You can also make comments if you would like anything changed. If "CHECK" or if "TODO" are written by somebody, it means that something needs to be checked or that it needs to be expanded; respectively. After the list is mostly completed, we could create a patch(es) to send to GCC. The quality of this list is not going to be great, treat it like a checklist. Obviously, if you want to discuss something about the changes, do quote the relevant section. So here it goes: BEGIN CHANGES_LIST GCC 12 - - Further library improvements in both quality and performance. - The use of contracts has been extended in the "Ada library" allowing for further checks at runtime or a deeper static analysis with the SPARK prover. - Further improvements to embedded systems such as VxWorks and RTMS. CHECK maybe be more specific/generic. GCC 11 - Introduction of the -gnat2022 flag in gnatmake. It enables newer features present in Ada 2022 (still to be ratified). This features are still experimental. - The parallel keyword is still unsupported. - TODO name the additional features. See [1], obviously, with some code examples. - Addition of the Jorvik profile. CHECK, see [2], maybe code examples? - Additional non-standard features [3]. CHECK if this applies to GCC 11 or 12. - A bug was fixed were previous GCC versions allowed XXX construct CHECK. This is not allowed by the standard. Some software was making use of XXX (which is, once again, not allowed) and it has to be patched. - General library improvements in both clarity and performance. - The use of contracts has been extended in the "Ada library" allowing for further checks at runtime or a deeper static analysis with the SPARK prover. - Further improvements to embedded systems such as VxWorks and RTMS. CHECK maybe be more specific/generic. GCC 10 - Some Ada 2022 features are available already with the use of the -gnatX (gnat eXtensions switch). - GCC 9 - - PREVIOUS GCCs (I will not explicitly name them, feel free to add info here) References [1] https://blog.adacore.com/ada-202x-support-in-gnat [2] https://blog.adacore.com/introduction-to-jorvik [3] https://blog.adacore.com/going-beyond-ada-2022 END CHANGES_LIST Regards, -- Fernando Oleo Blanco https://irvise.xyz
