OpenACC in Flang

Intentional deviation from the specification

  • The end directive for combined construct can omit the loop keyword.
  • An !$acc routine with no parallelism clause is treated as if the seq clause was present.
  • !$acc end loop does not trigger a parsing error and is just ignored.
  • The restriction on !$acc data required clauses is emitted as a portability warning instead of an error as other compiler accepts it.
