* [OPENMP50]Basic support for conditional lastprivate.Alexey Bataev2019-12-241-4/+11

* [OpenMP] Require trivially copyable type for mappingJonas Hahnfeld2019-12-071-9/+9
| | | | | | | | | | | | | A trivially copyable type provides a trivial copy constructor and a trivial copy assignment operator. This is enough for the runtime to memcpy the data to the device. Additionally there must be no virtual functions or virtual base classes and the destructor is guaranteed to be trivial, ie performs no action. The runtime does not require trivial default constructors because on alloc the memory is undefined. Thus, weaken the warning to be only issued if the mapped type is not trivially copyable.

* [OpenMP] Replace predetermined shared for const variableJoel E. Denny2019-01-041-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following appears in OpenMP 3.1 sec. 2.9.1.1 as a predetermined data-sharing attribute: > Variables with const-qualified type having no mutable member are > shared. It does not appear in OpenmP 4.0, 4.5, or 5.0. This patch removes the implementation of that attribute when the requested OpenMP version is greater than 3.1. One effect of that removal is that `default(none)` affects const variables without mutable members. Also, without this patch, if a const variable without mutable members was explicitly lastprivate or private, it was an error because it was predetermined shared. Now, clang instead complains that it's const without mutable fields, which is a more intelligible diagnostic. That should be fine for all of the above versions because they all have something like the following, which is quoted from OpenMP 5.0 sec. 2.19.3: > A variable that is privatized must not have a const-qualified type > unless it is of class type with a mutable member. This restriction does > not apply to the firstprivate clause. reduction and linear clauses already have separate checks for const variables. Future patches will merge the implementations.
