* [OPENMP]Disable ADL in C for user-defined reductions.Alexey Bataev2019-03-131-0/+10
| | | | | | C does not support ADL, disable it for C to prevent compiler crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@356089 91177308-0d34-0410-b5e6-96231b3b80d8
* [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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@321560 91177308-0d34-0410-b5e6-96231b3b80d8
* [OPENMP 4.0] Initial support for 'omp declare reduction' construct.Alexey Bataev2016-03-031-0/+52
Add parsing, sema analysis and serialization/deserialization for 'declare reduction' construct. User-defined reductions are defined as #pragma omp declare reduction( reduction-identifier : typename-list : combiner ) [initializer ( initializer-expr )] These custom reductions may be used in 'reduction' clauses of OpenMP constructs. The combiner specifies how partial results can be combined into a single value. The combiner can use the special variable identifiers omp_in and omp_out that are of the type of the variables being reduced with this reduction-identifier. Each of them will denote one of the values to be combined before executing the combiner. It is assumed that the special omp_out identifier will refer to the storage that holds the resulting combined value after executing the combiner. As the initializer-expr value of a user-defined reduction is not known a priori the initializer-clause can be used to specify one. Then the contents of the initializer-clause will be used as the initializer for private copies of reduction list items where the omp_priv identifier will refer to the storage to be initialized. The special identifier omp_orig can also appear in the initializer-clause and it will refer to the storage of the original variable to be reduced.
