* [OpenMP] Fix trailing space when printing pragmas, by Joel. E. DennyAlexey Bataev2018-02-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: -ast-print prints omp pragmas with a trailing space. While this behavior is likely of little concern to most users, surely it's unintentional, and it's annoying for some source-level work I'm pursuing. This patch focuses on omp pragmas, but it also fixes init_seg and loop hint pragmas because they share implementation. The testing strategy here is to add usually just one '{{$}}' per relevant -ast-print test file. This seems to achieve good code coverage. However, this strategy is probably easy to forget as the tests evolve. That's probably fine as this fix is far from critical. The main goal of the testing is to aid the initial review. This patch also adds a fixme for "#pragma unroll", which prints as "#pragma unroll (enable)", which is invalid syntax.

* [OPENMP] Support for -fopenmp-simd option with compilation of simd loopsAlexey Bataev2017-12-291-0/+4
| | | | | | | | | only. Added support for -fopenmp-simd option that allows compilation of simd-based constructs without emission of OpenMP runtime calls. llvm-svn: 321560

* [OPENMP] Add restriction for reduction clause in taskloop directives.Alexey Bataev2017-07-111-4/+4
| | | | | | | | Added checks for the reduction clauses in the taskloop directives: 1. Only addressable items must be used in reduction clauses. 2. Reduction clauses cannot be used with nogroup clauses. llvm-svn: 307693
* [OPENMP] Initial support for taskloop reductions.Alexey Bataev2017-06-301-8/+8
| | | | | | Add sema/parsupping ort for taskloop [simd] reductions. llvm-svn: 306825
* [OPENMP] Fix for PR31428: variable named like directive name modifierAlexey Bataev2016-12-201-3/+3
| | | | | | | | Directive name modifiers in 'if' clause are allowed only for OpenMP 4.5 and higher + in OpenMP 4.5 parsing procedure emits error message if ':' is not found after directive name modifier. llvm-svn: 290175
* Make output of -ast-print a valid C++ code.Serge Pavlov2016-11-101-0/+1
| | | | | | | | | | | | | | | | | | Output generated by option -ast-print looks like C/C++ code, and it really is for plain C. For C++ the produced output was not valid C++ code, but the differences were small. With this change the output is fixed and can be compiled. Tests are changed so that output produced by -ast-print is compiled again with the same flags and both outputs are compared. Option -ast-print is extensively used in clang tests but it itself was tested poorly, existing tests only checked that compiler did not crash. There are unit tests in file DeclPrinterTest.cpp, but they test only terse output mode. Differential Revision: https://reviews.llvm.org/D26452 llvm-svn: 286439
