Bug ID: 92970
Summary: OpenACC 2.5: 'acc_delete' etc. on non-present data is
a no-op
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: openacc
Severity: normal
Priority: P3
Component: libgomp
Assignee: unassigned at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
CC: burnus at gcc dot gnu.org, jakub at gcc dot gnu.org,

Target Milestone: ---
OpenACC 2.5 states that 'acc_delete' etc. on non-present data is a no-op.
Note that this (silently!) changed in OpenACC 2.6 ff.: "a runtime error is
issued". I filed <https://github.com/OpenACC/openacc-spec/issues/251> "OpenACC
2.5 vs. 2.6 ff. difference in 'acc_delete' etc. for non-present data".
GCC trunk should currently be implementing the OpenACC 2.5 semantics, but we
fail (at least for some variants). I know of course how to easily fix this,
but will wait to first get the intended OpenACC semantics clarified.
