https://github.com/Leporacanthicus created https://github.com/llvm/llvm-project/pull/111562

The bulk of this change are new tests to check that we get a "Not yet implemneted: *some stuff here*" message when using some not yet supported OpenMP functionality.

For some of these cases, this also means adding additional clauses to a filter list in OpenMP.cpp - this changes nothing [to the best of my understanding] other than allowing the clause to get to the point where it can be rejected in a TODO with a more clear message. One of the TOOD filters were missing Mergeable clause, so this was also added and the existing test updated for the new more specific error message.

There is no functional change intended here.

Subject: [PATCH] [Flang][OpenMP]Add tests for TODOs and small changes to
 improve messages

The bulk of this change are new tests to check that we get a
"Not yet implemneted: *some stuff here*" message when using some not yet
supported OpenMP functionality.

For some of these cases, this also means adding additional clauses to
a filter list in OpenMP.cpp - this changes nothing [to the best of
my understanding] other than allowing the clause to get to the point
where it can be rejected in a TODO with a more clear message. One of
the TOOD filters were missing Mergeable clause, so this was also added
and the existing test updated for the new more specific error message.

There is no functional change intended here.
