Hi!
(I'm not involved in or familiar with Sandra's Fortran TS29113 work, just
commenting generally here.)

That's not current practice, as far as I can tell. I'm certainly
"guilty" of pushing lots of XFAILed test cases (or, most often,
individual XFAILed DejaGnu directives), and I see a good number of others
GCC folks do that, too. Ideally with but casually also without
corresponding GCC PRs filed. If without, then of course should have
suitable commentary inside the test case file. Time span of addressing
the XFAILs ranging between days and years.
In my opinion, if a test case has been written and analyzed, why
shouldn't you push it, even if (parts of) it don't quite work yet? (If
someone -- at another time, possibly -- then implements the missing
functionality/fixes the bugs, the XFAILs turn into XPASSes, thus serving
to demonstrate the effect of code changes.
Otherwise -- and I've run into that just yesterday... -- effort spent on
such test cases simply gets lost "in the noise of the mailing list
archives", until re-discovered, or -- in my case -- re-implemented and
then re-discovered by chance.
We nowadays even have a way to mark up ICEing test cases ('dg-ice'),
which has been used to push test cases that ICE for '{ target *-*-* }'.
Of course, we shall assume a certain level of quality in the XFAILed test
cases: I'm certainly not suggesting we put any random junk into the
testsuite, coarsely XFAILed. (I have not reviewed Sandra's test cases to
that effect, but knowing here, I'd be surprised if that were the problem
here.)
Not trying to overrule you, just sharing my opinion -- now happy to hear
others. :-)
Grüße
Thomas
