            Bug ID: 109124
           Summary: 'libgomp.oacc-c-c++-common/data-2-lib.c',
                    'libgomp.oacc-c-c++-common/data-2.c' GCN offloading
                    execution test FAILs
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Keywords: openacc
          Severity: normal
          Priority: P3
         Component: libgomp
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tschwinge at gcc dot gnu.org

  Target Milestone: ---

With my recent commit r13-6590-gf8332e52a498df480f72303de32ad0751ad899fe "Use
'GOMP_MAP_VARS_TARGET' for OpenACC compute constructs [PR90596]", the
'libgomp.oacc-c-c++-common/data-2-lib.c', 'libgomp.oacc-c-c++-common/data-2.c'
GCN offloading execution test started FAILing (almost) always.  (Exception:
(default) '-march=fiji', but probably rather due to differences in
hardware/parallelism capabilities?)


There's been some discussion about those test cases in
<https://inbox.sourceware.org/gcc-patches/20190910174143.46888-2-julian@codesourcery.com>
"Improve async serialize implementation for AMD GCN libgomp plugin" that I need
to look into.
