[developer] Heads Up: Compiler and Shadow Updates Available

[developer] Heads Up: Compiler and Shadow Updates Available

[Robert Mustacchi]

Hi all,

We have recently made two groups of changes to the compilers for illumos:

* We have taught gcc how to understand %z and %j in cmn_err as a
corresponding piece to https://www.illumos.org/issues/16768. This is
tagged as gcc-10.4.0-il-2:
https://github.com/illumos/gcc/releases/tag/gcc-10.4.0-il-2.

* We have prepared gcc 14.2.0. This will soon become the new shadow.
This has been tagged as gcc-14.2.0-il-1:
https://github.com/illumos/gcc/releases/tag/gcc-14.2.0-il-1.

Distributions, we ask that you please update the versions of gcc10 you
have for building illumos to the -il-2 tag. We also ask that you provide
the patched gcc14 -il-1 tag as well. We are planning on making gcc
14.2.0-il-1 the new shadow soon. We will be updating the version of gcc
10 at the same time to have the cmn_err features. Your aid in making
sure that we have compilers ready ahead of this transition is appreciated.

If you have any questions, please don't hesitate to reach out.

Robert

With the release of r151052 today, OmniOS is ready for this transition.

gcc 14.2.0-il-1 is available as pkg://developer/gcc14 for both this new
release, for the long-term-supported r151046 release and for the rolling
bloody release. pkg://developer/gcc10 has also been updated to include the
patches from the latest -il-2 tag. Once the switch is made, we'll just need to
update the illumos-tools meta package and the shipped example env files under
/opt/onbld/env.

Anyone on r151050 or the now unsupported r151048 will need to upgrade to
r151052 in order to continue building gate once the new shadow is required
and we start allowing the new format specifiers in the kernel.

Thanks for co-ordinating this Robert, and thank you to everyone who has
been involved in the work to get gate gcc 14 clean over the past couple of
years.

Andy

Beautiful.  I always keep my HDC (including my zone that builds -gate) on Stable, so I'll be happy to run some -gate builds with gcc14 in the mix once '052 is available.

Thanks!
