* [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]Provide correct data sharing attributes for loop controlAlexey Bataev2019-07-181-4/+4
| | | | | | | | | | | | variables. Loop control variables are private in loop-based constructs and we shall take this into account when generate the code for inner constructs. Currently, those variables are reported as shared in many cases. Moved the analysis of the data-sharing attributes of the loop control variable to an early semantic stage to correctly handle their attributes. llvm-svn: 366474

Compiler did not generate error reports for the variables used in other OpenMP regions. Patch fixes this. llvm-svn: 345533
* [OPENMP] Support for -fopenmp-simd option with compilation of simd loopsAlexey Bataev2017-12-291-0/+2
| | | | | | | | | only. Added support for -fopenmp-simd option that allows compilation of simd-based constructs without emission of OpenMP runtime calls. llvm-svn: 321560
* [OPENMP] Do not allow variables to be first|last-privates inAlexey Bataev2017-12-011-5/+8

* [OpenMP] Sema and parsing for 'distribute simd' pragmaKelvin Li2016-07-061-0/+359
Summary: This patch is an implementation of sema and parsing for the OpenMP composite pragma 'distribute simd'. Differential Revision: http://reviews.llvm.org/D22007 llvm-svn: 274604
