If the sub-tickets are not closed, then the assumption should be they still
need to be addressed.

It is pretty easy to check that the ticket still applies. There has to be
an implementation of the missing
method(s) in newlib or RTEMS.

The highest priority methods in my opinion are those that are missing in
the
FACE General Purpose Profile (Edition 3.0). RTEMS has good alignment with
the FACE Safety Extended Profile but is missing some methods for FACE
General
Purpose Profile. Our conformance report is here:

https://docs.rtems.org/branches/master/posix-compliance/posix-compliance.html#face-3-0-general-purpose

Match the missing methods vs tickets and if something looks questionable or
confusing,
just ask.

FACE is an Open Group standard that started in the avionics community. It
defines
four operating system profiles. For the POSIX profiles, RTEMS does well
against the
lower 3 (Security, Safety Base, and Safety Extended).
https://opengroup.org/face.

That said, I think a lot of the missing methods for FACE GPP are math
related
and likely would need to be ported to newlib from an appropriately licensed
project like some FreeBSD.

This project is primarily identifying properly licensed versions of the
missing
POSIX methods, porting them to newlib/RTEMS, and adding tests.

We try to be good at creating tickets when we get ideas. I hope
there aren't many we forgot to do that for. But there might be some
from other people.
