            Bug ID: 105332
           Summary: [OpenMP] Remove bogus 'ALIGNED clause must be POINTER,
                    ALLOCATABLE, Cray pointer or C_PTR'
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: openmp, rejects-valid
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
  Target Milestone: ---

GCC rejects code with
  'ALIGNED clause must be POINTER, ALLOCATABLE, Cray pointer or C_PTR'

but that restriction is not in OpenMP 5.1.


(The restriction did get into OpenMP 5.2 during the syntax restructuring, but
it
seems to be an accidental change. On the spec side is tracked in
https://github.com/OpenMP/spec/issues/3279 (non-public) – and I expect that
this
restriction gets deleted for the next TR (and then OpenMP 6.0).)

--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Cf. also https://github.com/OpenMP/spec/pull/3318 (non public pull request).

New wording for ALIGN clause is that it takes an ARRAY but there are no
additional restrictions.

This applies both to 'declare simd' and to 'simd'.

In 5.1, the restrictions for the 'aligned' clause differed between 'simd' and
'declare simd'; 5.2 unified the restrictions; thus, introducing the issue of
