* [OPENMP] Generalize codegen for 'sections'-based directive.Alexey Bataev2016-01-221-8/+3
| | | | | | If 'sections' directive has only one sub-section, the code for 'single'-based directive was emitted. Removed this codegen, because it causes crashes in different cases. llvm-svn: 258495
* [OPENMP] Remove explicit call for implicit barrierAlexey Bataev2015-12-181-3/+0
| | | | | | | #pragma omp parallel needs an implicit barrier that is currently done by an explicit call to __kmpc_barrier. However, the runtime already ensures a barrier in __kmpc_fork_call which currently leads to two barriers per region per thread. Differential Revision: http://reviews.llvm.org/D15561 llvm-svn: 255992
* [OPENMP] Outlined function for parallel and other regions with list of ↵Alexey Bataev2015-09-101-2/+2
| | | | | | | | | captured variables. Currently all variables used in OpenMP regions are captured into a record and passed to outlined functions in this record. It may result in some poor performance because of too complex analysis later in optimization passes. Patch makes to emit outlined functions for parallel-based regions with a list of captured variables. It reduces code for 2*n GEPs, stores and loads at least. Codegen for task-based regions remains unchanged because runtime requires that all captured variables are passed in captured record. llvm-svn: 247251

* [OPENMP 4.0] Fixed codegen for 'cancellation point' construct.Alexey Bataev2015-07-031-2/+2
| | | | | | | | | | Generate the next code for 'cancellation point': if (__kmpc_cancellationpoint()) { __kmpc_cancel_barrier(); <exit construct>; } llvm-svn: 241336
* [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] Initial codegen for 'parallel sections' directive.Alexey Bataev2015-04-141-0/+98
Emits code for outlined 'parallel' directive with the implicitly inlined 'sections' directive: ... call __kmpc_fork_call(..., outlined_function, ...); ... define internal void outlined_function(...) { <code for implicit sections directive>; } Differential Revision: http://reviews.llvm.org/D8997 llvm-svn: 234849
