I wonder why you didn't raise your concerns 1 1/2 years ago when I
announced the obsoletion of Solaris 11.3 support?

The Solaris 11.3 ESUs (Extended Support Updates) are available at a
premium only, and just contain the bare minimum of security updates,
often 6 to 9 month in between.

Do you have any indication on the size of the userbase? I seriously
doubt it's large beyond some hobbyists that keep the old hardware
running.
You also seem to forget that my GCC (and LLVM) Solaris support work is
purely voluntary, done in my spare time.
Keeping Solaris 11.3 support working would be much more than restoring
the removal patch:
* For each and every of my Solaris patches, I'd have to investigate if
it works on 11.3 or needs adjustments and workarounds.
* I'd also need to regularly test the result to keep things working.
I honestly don't have the time or the energy to do this, nor the
hardware required for testing Besides, I have too much on my plate
already, and rather spend it on more beneficial work.
Above all, I always wonder why people insist on running ancient hardware
with an almost-unsupported OS, but require a bleeding edge version of
GCC. What's wrong with continuing to use GCC 13 (or even 14, although I
haven't tested that on Solaris 11.3) instead?

As has been noted, SPARC is on its way out for Illumos.
