2020-06-26c++: Change the default dialect to C++17.Marek Polacek1-1/+2
Since GCC 9, C++17 support is no longer experimental. It was too late to change the default C++ dialect to C++17 in GCC 10, but I think now it's time to pull the trigger (C++14 was made the default in GCC 6.1). We're still missing two C++17 library features, but that shouldn't stop us. See <https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2017> and <https://gcc.gnu.org/projects/cxx-status.html#cxx17> for the C++17 status. I won't list all C++17 features here, but just a few heads-up: - trigraphs were removed (hardly anyone cares, unless your keyboard is missing the # key), - operator++(bool) was removed (so some tests now run in C++14 and down only), - the keyword register was removed (some legacy code might trip on this), - noexcept specification is now part of the type system and C++17 does not allow dynamic exception specifications anymore (the empty throw specification is still available, but it is deprecated), - the evaluation order rules are different in C++17, - static constexpr data members are now implicitly inline (which makes them definitions), - C++17 requires guaranteed copy elision, meaning that a copy/move constructor call might be elided completely. That means that if something relied on a constructor being instantiated via e.g. copying a function parameter, it might now fail. I'll post an update for cxx-status.html and add a new caveat to changes.html once this is in. gcc/ChangeLog: * doc/invoke.texi (C Dialect Options): Adjust -std default for C++. * doc/standards.texi (C Language): Correct the default dialect.

2020-05-19openmp: Add basic library allocator support.Jakub Jelinek3-0/+231
This patch adds very basic allocator support (omp_{init,destroy}_allocator, omp_{alloc,free}, omp_[sg]et_default_allocator). The plan is to use memkind (likely dlopened) for high bandwidth memory, but that part isn't implemented yet, probably mlock for pinned memory and see what other options there are for other kinds of memory. For offloading targets, we need to decide if we want to support the dynamic allocators (and on which targets), or if e.g. all we do is at compile time replace omp_alloc/omp_free calls with constexpr predefined allocators with something special. And allocate directive and allocator/uses_allocators clauses are future work too. 2020-05-19 Jakub Jelinek <jakub@redhat.com> * omp.h.in (omp_uintptr_t): New typedef. (__GOMP_UINTPTR_T_ENUM): Define.

2020-03-19c++: Fix up handling of captured vars in lambdas in OpenMP clauses [PR93931]Jakub Jelinek1-0/+120
Without the parser.c change we were ICEing on the testcase, because while the uses of the captured vars inside of the constructs were replaced with capture proxy decls, we didn't do that for decls in OpenMP clauses. With that fixed, we don't ICE anymore, but the testcase is miscompiled and FAILs at runtime. This is because the capture proxy decls have DECL_VALUE_EXPR and during gimplification we were gimplifying those to their DECL_VALUE_EXPRs. That is fine for shared vars, but for privatized ones we must not do that. So that is what the cp-gimplify.c changes do. Had to add a DECL_CONTEXT check before calling is_capture_proxy because some VAR_DECLs don't have DECL_CONTEXT set (yet) and is_capture_proxy relies on that being non-NULL always. 2020-03-19 Jakub Jelinek <jakub@redhat.com> PR c++/93931 * parser.c (cp_parser_omp_var_list_no_open): Call process_outer_var_ref on outer_automatic_var_p decls. * cp-gimplify.c (cxx_omp_disregard_value_expr): Return true also for capture proxy decls. * testsuite/libgomp.c++/pr93931.C: New test.

2020-02-13openmp: ignore nowait if async execution is unsupported [PR93481]Frederik Harwath2-6/+0
An OpenMP "nowait" clause on a target construct currently leads to a call to GOMP_OFFLOAD_async_run in the plugin that is used for offloading at execution time. The nvptx plugin contains only a stub of this function that always produces a fatal error if called. This commit changes the "nowait" implementation to ignore the clause if the executing device's plugin does not implement GOMP_OFFLOAD_async_run. The stub in the nvptx plugin is removed which effectively means that programs containing "nowait" can now be executed with nvptx offloading as if the clause had not been used. This behavior is consistent with the OpenMP specification which says that "[...] execution of the target task *may* be deferred" (emphasis added), cf. OpenMP 5.0, page 172. libgomp/ * plugin/plugin-nvptx.c: Remove GOMP_OFFLOAD_async_run stub. * target.c (gomp_load_plugin_for_device): Make "async_run" loading optional.

2020-02-09openmp: Optimize DECL_IN_CONSTANT_POOL vars in target regionsJakub Jelinek1-0/+28
DECL_IN_CONSTANT_POOL are shared and thus don't really get emitted in the BLOCK where they are used, so for OpenMP target regions that have initializers gimplified into copying from them we actually map them at runtime from host to offload devices.
