2019-11-12Add OpenACC 2.6 `serial' construct supportMaciej W. Rozycki
The `serial' construct (cf. section 2.5.3 of the OpenACC 2.6 standard) is equivalent to a `parallel' construct with clauses `num_gangs(1) num_workers(1) vector_length(1)' implied. These clauses are therefore not supported with the `serial' construct. All the remaining clauses accepted with `parallel' are also accepted with `serial'. The `serial' construct is implemented like `parallel', except for hardcoding dimensions rather than taking them from the relevant clauses, in `expand_omp_target'. Separate codes are used to denote the `serial' construct throughout the middle end, even though the mapping of `serial' to an equivalent `parallel' construct could have been done in the individual language frontends. In particular, this allows to distinguish between compute constructs in warnings, error messages, dumps etc. 2019-11-12 Maciej W.

2019-02-14Fix PR72715 "ICE in gfc_trans_omp_do, at fortran/trans-openmp.c:3164"Cesar Philippidis
The OpenACC 'resolve_oacc_nested_loops' function duplicates most code of the OpenMP 'resolve_omp_do', but didn't include the PR60127 "ICE with OpenMP and DO CONCURRENT" (trunk r210331) changes. (Probably the two functions should be unified?) The Fortran DO CONCURRENT construct is a way to tell the compiler that loop iterations don't have any interdependencies -- which is information that would very well be suitable for OpenACC/OpenMP loops. There are some "details" however, see the discussion/references in PR60127, so for the time being, make this a compile-time error instead of an ICE. gcc/fortran/ * openmp.c (resolve_oacc_nested_loops): Error on do concurrent loops. gcc/testsuite/ * gfortran.dg/goacc/loop-3-2.f95: Error on do concurrent loops. * gfortran.dg/goacc/loop-3.f95: Likewise. * gfortran.dg/goacc/pr72715.f90: New test.
