Bug ID: 99519
Summary: [OpenMP] PRIVATE/FIRSTPRIVATE with CLASS / polymorphic
list items
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code, openmp
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
Target Milestone: ---
Follow-up to PR86470.
Class variables need some special handling for PRIVATE/FIRSTPRIVATE in
data-sharing constructs like:
class(*), allocatable :: var1, var2
...
!$omp parallel private(var1) firstprivate(var2)
...
!$omp end parallel
The following patch handles FIRSTPRIVATE:
https://gcc.gnu.org/pipermail/gcc-patches/2021-March/566529.html
Missing:
* PRIVATE - which causes still ICEs, even though not for PR86470.
→ use dynamic type of var, apply default initializers
* Polymorphic arrays not supported by FIRSTPRIVATE patch
* Check that for TYPE, the default initializer is applied
- what about the finalizer?
