* [OPENMP] Fix PR38398: compiler crash on standalone pragma ordered with ↵Alexey Bataev2018-02-151-0/+2
| | | | | | | | | depend sink|source clause. Patch fixes compiler crash on standalone #pragmas ordered with depend(sink|source) clauses. llvm-svn: 325302
* [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] fix seg-faults printing diagnostics with invalid ordered(n) valuesRachel Craik2017-09-191-0/+8
| | | | | | | | | | | When the value specified for n in ordered(n) is larger than the number of loops a segmentation fault can occur in one of two ways when attempting to print out a diagnostic for an associated depend(sink : vec): 1) The iteration vector vec contains less than n items 2) The iteration vector vec contains a variable that is not a loop control variable This patch addresses both of these issues.

* [Lit Test] Make tests C++11 compatible - OpenMP constant expressionsCharles Li2017-02-031-0/+11
| | | | | | | | C++11 introduced constexpr, hence the change in diagnostics. Differential Revision: https://reviews.llvm.org/D29480 llvm-svn: 294025
* [OPENMP 4.5] Parsing/sema for 'depend(sink:vec)' clause in 'ordered' directive.Alexey Bataev2015-12-231-8/+41
| | | | | | OpenMP 4.5 adds 'depend(sink:vec)' in 'ordered' directive for doacross loop synchronization. Patch adds parsing and semantic analysis for this clause. llvm-svn: 256330

| | | | | | | | directive. OpenMP 4.5 adds 'depend(source)' clause for 'ordered' directive to support cross-iteration dependence. Patch adds parsing and semantic analysis for this construct. llvm-svn: 255986
* [OPENMP 4.1] Add 'simd' clause for 'ordered' directive.Alexey Bataev2015-09-281-0/+92
| | | | | | | | | | | Parsing and sema analysis for 'simd' clause in 'ordered' directive. Description If the simd clause is specified, the ordered regions encountered by any thread will use only a single SIMD lane to execute the ordered regions in the order of the loop iterations. Restrictions An ordered construct with the simd clause is the only OpenMP construct that can appear in the simd region llvm-svn: 248696
* [OPENMP 4.1] Add 'threads' clause for '#pragma omp ordered'.Alexey Bataev2015-09-251-0/+42
| | | | | | | | OpenMP 4.1 extends format of '#pragma omp ordered'. It adds 3 additional clauses: 'threads', 'simd' and 'depend'. If no clause is specified, the ordered construct behaves as if the threads clause had been specified. If the threads clause is specified, the threads in the team executing the loop region execute ordered regions sequentially in the order of the loop iterations. The loop region to which an ordered region without any clause or with a threads clause binds must have an ordered clause without the parameter specified on the corresponding loop directive. llvm-svn: 248569
* [OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492)Alexey Bataev2015-05-201-1/+1
| | | | | | | -fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).
