            Bug ID: 109998
           Summary: [OpenMP] TR12/5.0/5.1 - permit structure elements with
                    '!$OMP ALLOCATORS' (and !$OMP ALLOCATE)
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Keywords: openmp
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
  Target Milestone: ---

Cf. r14-1301-gd64e8e1224708e7f5b87c531aeb26f1ed07f91ff and in particular
in openmp.cc the comment:

   Note that the executable ALLOCATE directive permits structure elements o=
nly
   in OpenMP 5.0 and 5.1 but not longer in 5.2.  See also the comment on the
   'omp allocators' directive below. The accidental change was reverted for
   OpenMP TR12, permitting them again. See also gfc_match_omp_allocators.

   Hence, structure elements are rejected for now, also to make resolving
   OMP_LIST_ALLOCATE simpler (check for duplicates, same symbol in
   Fortran allocate stmt).  TODO: Permit structure elements.


EXPECTED: What the TODO says.


For TR12 (OpenMP Spec Issue 3437), the description in the "allocators
directive" section was changed to state:

"The list items that appear in an *allocate* clause may include structure
elements."

(It does not talk about the *allocate* directive any more as TR11/TR12/6.0
removed deprecated features.)=
