2019-11-12Add OpenACC 2.6 `serial' construct supportMaciej W. Rozycki1-0/+10
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.

2019-11-06Warn about inconsistent OpenACC nested reduction clausesFrederik Harwath1-0/+11
OpenACC (cf. OpenACC 2.7, section 2.9.11. "reduction clause"; this was first clarified by OpenACC 2.6) requires that, if a variable is used in reduction clauses on two nested loops, then there must be reduction clauses for that variable on all loops that are nested in between the two loops and all these reduction clauses must use the same operator. This commit introduces a check for that property which reports warnings if it is violated. 2019-11-06 Gergö Barany <gergo@codesourcery.com> Frederik Harwath <frederik@codesourcery.com> Thomas Schwinge <thomas@codesourcery.com> gcc/ * omp-low.c (struct omp_context): New fields local_reduction_clauses, outer_reduction_clauses.
