Bug ID: 114283
Summary: [OpenMP] Dummy procedures/proc pointers and
'defaultmap', 'default', 'firstprivate' etc.
Product: gcc
Version: 14.0
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: ---
See also OpenMP specification Issue #3823 [and slightly related PR 114282].
There are two cases:
(A) Dummy procedures
IMHO those aren't variables and gfortran also rejects them when used in
firstprivate, map, shared etc. ("Object 'f1' is not a variable").
However, gfortran does complain with 'default(none)':
Error: 'f1' not specified in enclosing 'target'
Note: 'default(none)' does not diagnose it.
EXPECTED: There is no diagnosis for 'defaultmap(none)'.
(B) Procedure pointers
Here it is unclear whether it should be regarded as variable or not; gfortran
treats those as variables.
Depends on OpenMP specification Issue #3823.
It seems as if handling it as variable, but using 'firstprivate' as default for
implicit mapping makes most sense. – But also treating it as non-variable would
make sense.
