commit 4ede915d5dde935a16df2c6640aee5ab22348d30
Author: Tobias Burnus <tobias@codesourcery.com>
Date: Tue Jun 6 16:47:16 2023 +0200
openmp: Add support for the 'present' modifier
This implements support for the OpenMP 5.1 'present' modifier, which can be
used in map clauses in the 'target', 'target data', 'target data enter' and
'target data exit' constructs, and in the 'to' and 'from' clauses of the
'target update' construct. It is also supported in defaultmap.
The modifier triggers a fatal runtime error if the data specified by the
clause is not already present on the target device. It can also be combined
with 'always' in map clauses.
