Bug ID: 114690
Summary: OpenMP 'indirect' clause: dynamic image
loading/unloading
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Keywords: openmp
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,
kcy at codesourcery dot com
Target Milestone: ---
The OpenMP 'indirect' clause mapping table is not populated at image load time
(host-side), but upon the first device kernel invocation (device-side:
'build_indirect_map'), and is then immutable.
This is sufficient for a lot of cases, but breaks if additional images are
loaded after the first device kernel invocation (new mappings not added), or if
images get unloaded (stale mappings not retired).
