* [OPENMP] Support for -fopenmp-simd option with compilation of simd loopsAlexey Bataev2017-12-291-0/+5
| | | | | | | | | only. Added support for -fopenmp-simd option that allows compilation of simd-based constructs without emission of OpenMP runtime calls. llvm-svn: 321560

* Remove unnecessary x86 backend requirements from OpenMP testsReid Kleckner2016-10-211-1/+0
| | | | | | Clang can generate LLVM IR for x86 without a registered x86 backend. llvm-svn: 284836

| | | | | | | | modifiers. OpenMP 4.5 adds support for monotonic/nonmonotonic modifiers in 'schedule' clause. Add codegen for these modifiers. llvm-svn: 256666
* [OPENMP 4.5] Allow 'ordered' clause on 'loop simd' constructs.Alexey Bataev2015-12-301-0/+8
| | | | | | OpenMP 4.5 allows to use 'ordered' clause without parameter on 'loop simd' constructs. llvm-svn: 256639
* [OPENMP 4.1] Codegen for ‘simd’ clause in ‘ordered’ directive.Alexey Bataev2015-09-291-0/+17
| | | | | | | | | | | 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. An ordered directive with ‘simd’ clause is generated as an outlined function and corresponding function call to prevent this part of code from vectorization later in backend. llvm-svn: 248772
* [OPENMP 4.1] Add 'threads' clause for '#pragma omp ordered'.Alexey Bataev2015-09-251-2/+2
| | | | | | | | 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 4.0] Fixed codegen for 'cancellation point' construct.Alexey Bataev2015-07-031-4/+4
| | | | | | | | | | Generate the next code for 'cancellation point': if (__kmpc_cancellationpoint()) { __kmpc_cancel_barrier(); <exit construct>; } llvm-svn: 241336
* [OPENMP] Fix codegen for ordered loop directives.Alexey Bataev2015-05-201-13/+15
| | | | | | loops with ordered clause must be generated the same way as dynamic loops, but with static scheduleing. llvm-svn: 237788
* [OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492)Alexey Bataev2015-05-201-3/+3
| | | | | | | -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).

* [OPENMP] Generate !llvm.mem.loop_parallel_access metadata for loops with ↵Alexey Bataev2015-05-071-0/+4
| | | | | | | | | | dynamic/guided scheduling. Inner bodies of OpenMP worksharing loop-based constructs with dynamic or guided scheduling are allowed to be marked with !llvm.mem.parallel_loop_access metadata for better optimization. Worksharing constructs with static scheduling cannot be marked this way (according to OpenMP standard "A data dependence between the same logical iterations in two such loops is guaranteed"). Constructs with auto and runtime scheduling are also not marked because automatically chosen scheduling may be static also. Differential Revision: http://reviews.llvm.org/D9518 llvm-svn: 236693
* [OPENMP] Codegen for 'ordered' directive.Alexey Bataev2015-04-221-0/+211
Add codegen for 'ordered' directive: __kmpc_ordered(ident_t *, gtid); <associated statement>; __kmpc_end_ordered(ident_t *, gtid); Also for 'for' directives with the dynamic scheduling and an 'ordered' clause added a call to '__kmpc_dispatch_fini_(4|8)[u]()' function after increment expression for loop control variable: while(__kmpc_dispatch_next(&LB, &UB)) { idx = LB; while (idx <= UB) { BODY; ++idx; __kmpc_dispatch_fini_(4|8)[u](); // For ordered loops only. } // inner loop } Differential Revision: http://reviews.llvm.org/D9070 llvm-svn: 235496
