Thank you for working on C23 support.

I reviewed Paul's comments, and I agree with you that we can just add more points
to the auto-libm-test-in at any point in the future, and that adding them right
now is not in scope. We should focus on getting the implementation in place and
then add microbenchmarks and additional test values. I appreciate Paul's position,
but as a reviewer I want the minimum-viable feature to enter the project so we can
start getting broader coverage downstream in distributions.

I reviewed Adhemerval's comments, and I agree with you that the patch that introduces
the API for libm does not *need* to have all the ULPs updated. Updating ULPS is a
continuous operation, we do it even today with i686 and x86_64 as we get new AMD
or Intel hardware. However, I expect that in short order the machine maintainers
should push updates. Also see: https://sourceware.org/glibc/wiki/Consensus#Bad_Changes

LGTM.

Agreed.

We don't document what is required to regenerate all of the files in glibc, and this
is unfortunate, but not a requirement for this patch.

OK.

OK. Perfect, a bmg test is sufficient IMO to cover the worst breakage.


This failed pre-commit CI for aarch64 and armv7hl:
https://patchwork.sourceware.org/project/glibc/patch/41a4a6c9-4942-a9be-9459-1aaeb44ffee8@redhat.com/
... but the test artifacts are missing?

I assume these are just other arches needing updated libm-test-ulps.

It is 100% OK with me to do it this way, other machine maintainres need to update the
ulps for their targets before release.

OK. I wondered if assafe and acsafe were true, but in thise case they are.
