Trying GCC 13.1.0 (x86_64) on Ventura 13.3.1

Trying GCC 13.1.0 (x86_64) on Ventura 13.3.1

Hi Simon,

Many thanks for the x86 macOS build of GNAT.
Does it incorporate front-end updates since the Sep 30 build of 
gnat-12.2.0-1?

Using the command:

-fdata-sections -ffunction-sections -gnatfn -mtune=native -Ofast 
-fno-stack-check -fomit-frame-pointer -flto -I 
/Users/wf/KDF9/emulation/Source/ee9.adb

I got:

It includes whatever changes Adacore & fellow maintainers have made!
From here <https://gcc.gnu.org/gcc-13/changes.html>,

   Ada

   Traceback support added in RTEMS for the PPC ELF and ARM
      architectures.
   Support for versions older than VxWorks 7 has been removed.
   General improvements to the contracts in the standard libraries.
   Addition of GNAT.Binary_Search.
   Further additions and fixes for the Ada 2022 specification.
   The Pragma SPARK_Mode=>Auto is now accepted. Contract analysis has
      been further improved.
   Documentation improvements.

gcc -c -I./ -I../Source -funwind-tables -gnatl12j96 -gnatw.e -gnatwD
-gnatwH -gnatwP -gnatwT -gnatw.W -gnatw.B -gnatwC -gnatw.u -gnatyO

-mtune=native -O3 -flto -I-
/Users/simon/tmp/ee9/emulation/Source/ee9.adb

worked without complaint.

The command lines are different: I used V9p0p_for_Intel_macOS.zip,
command mk9.

This is on Darwin 21.6.0, with Command Line Tools 14.2, as reported by
$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables

Thanks for that pointer.
I guess I am wondering about this:

Where would AdaCore enumerate those updates?

As usual, you immediately put your finger on the problem:
out of date Command Line Tools (sigh).
I have installed 14.3 and all is now well.

Thanks again!

I can't speak for AdaCore, but I tried to search in ChangeLog and

Regarding the improvement of Ada 2022 support, I only found two cases. The 'Index attribute has been implemented for use in the preconditions and postconditions of input families. Containers have received versions of cursor operations where the first argument is the container object. These include Has_Element, Element, Next, and so on, i.e. we can write My_Set.Has_Element (Cursor).
