Bug ID: 88288
Summary: [OpenACC, libgomp] Adjust offsets for present data
clauses
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Keywords: openacc, patch
Severity: normal
Priority: P3
Component: libgomp
Assignee: tschwinge at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
CC: cesar at gcc dot gnu.org, jakub at gcc dot gnu.org
Target Milestone: ---
As reported in <https://gcc.gnu.org/ml/gcc-patches/2016-08/msg01676.html>,
libgomp "is not respecting the on device offset of subarrays which may arise in
present data clauses", "causing SPEC_ACCEL 304.olbm to generate bogus results",
for example.
This will likely need to be fixed on all active release branches.
