* [OPENMP 4.0] Fixed DSA analysis for taskloop directives.Alexey Bataev2016-04-131-0/+3
| | | | | | | Patch make clang to perform analysis for task-based directives also for taskloop-based directives. llvm-svn: 266198
* [OPENMP 4.0] Support for 'uniform' clause in 'declare simd' directive.Alexey Bataev2016-04-121-0/+5
| | | | | | | | | OpenMP 4.0 defines clause 'uniform' in 'declare simd' directive: 'uniform' '(' <argument-list> ')' The uniform clause declares one or more arguments to have an invariant value for all concurrent invocations of the function in the execution of a single SIMD loop. The special this pointer can be used as if was one of the arguments to the function in any of the linear, aligned, or uniform clauses. llvm-svn: 266041
* [OPENMP] Parsing and Sema support for 'omp declare target' directiveDmitry Polukhin2016-04-061-0/+2
| | | | | | | | | | | | | | | | | | | | Add parsing, sema analysis for 'declare target' construct for OpenMP 4.0 (4.5 support will be added in separate patch). The declare target directive specifies that variables, functions (C, C++ and Fortran), and subroutines (Fortran) are mapped to a device. The declare target directive is a declarative directive. In Clang declare target is implemented as implicit attribute for the declaration. The syntax of the declare target directive is as follows: #pragma omp declare target declarations-definition-seq #pragma omp end declare target Based on patch from Michael Wong http://reviews.llvm.org/D15321 llvm-svn: 265530
* [OPENMP 4.0] Initial support for '#pragma omp declare simd' directive.Alexey Bataev2016-03-301-0/+2
| | | | | | | | | | | | | | | | Initial parsing/sema/serialization/deserialization support for '#pragma omp declare simd' directive. The 'declare simd' construct can be applied to a function to enable the creation of one or more versions that can process multiple arguments using SIMD instructions from a single invocation from a SIMD loop. If the function has any declarations, then the declare simd construct for any declaration that has one must be equivalent to the one specified for the definition. Otherwise, the result is unspecified. This pragma can be applied many times to the same declaration. Internally this pragma is represented as an attribute. But we need special processing for this pragma because it must be used before function declaration, this directive is applied to.

* [OPENMP 4.0] Initial support for 'omp declare reduction' construct.Alexey Bataev2016-03-031-0/+1
| | | | | | | | | | | | | | | | | 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.

* [OPENMP 4.5] Sema/parsing support for extended format of 'schedule' clause.Alexey Bataev2015-12-281-5/+13
| | | | | | | | | OpenMP 4.0-3.1 supports the next format of ‘schedule’ clause: schedule(kind[, chunk_size]) Where kind can be one of ‘static’, ‘dynamic’, ‘guided’, ‘auto’ or ‘runtime’. OpenMP 4.5 defines the format: schedule([modifier [, modifier]:]kind[, chunk_size]) Modifier can be one of ‘monotonic’, ‘nonmonotonic’ or ‘simd’. llvm-svn: 256487

* [OpenMP] Capture global variables in target regions.Samuel Antao2015-10-021-0/+4
| | | | | | | | | All global variables that are not enclosed in a declare target region must be captured in the target region as local variables do. Currently, there is no support for declare target, so this patch adds support for capturing all the global variables used in a the target region. llvm-svn: 249154
* [OPENMP 4.1] Add 'simd' clause for 'ordered' directive.Alexey Bataev2015-09-281-0/+2
| | | | | | | | | | | 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 Bataev2015-09-251-1/+12
| | | | | | | | 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] Add 'if' clause for 'cancel' directive.Alexey Bataev2015-09-181-1/+10

* [OPENMP 4.1] Initial support for 'simdlen' clause.Alexey Bataev2015-08-211-0/+2
| | | | | | Add parsing/sema analysis for 'simdlen' clause in simd directives. Also add check that if both 'safelen' and 'simdlen' clauses are specified, the value of 'simdlen' parameter is less than the value of 'safelen' parameter. llvm-svn: 245692
* [OPENMP 4.1] Initial support for modifiers in 'linear' clause.Alexey Bataev2015-08-201-2/+15
| | | | | | | | | | | | | | | | | | | | | | OpenMP 4.1 adds 3 optional modifiers to 'linear' clause. Format of 'linear' clause has changed to: ``` linear(linear-list[ : linear-step]) ``` where linear-list is one of the following ``` list modifier(list) ``` where modifier is one of the following: ``` ref (C++) val (C/C++) uval (C++) ``` Patch adds parsing and sema analysis for these modifiers. llvm-svn: 245550

* [OPENMP] Support for '#pragma omp taskgroup' directive.Alexey Bataev2015-06-181-0/+1
| | | | | | | | | | | | | Added parsing, sema analysis and codegen for '#pragma omp taskgroup' directive (OpenMP 4.0). The code for directive is generated the following way: #pragma omp taskgroup <body> void __kmpc_taskgroup(<loc>, thread_id); <body> void __kmpc_end_taskgroup(<loc>, thread_id); llvm-svn: 240011
* [OPENMP] Codegen for 'copyin' clause in 'parallel' directive.Alexey Bataev2015-04-161-2/+1
| | | | | | | | | | | | | | | Emits the following code for the clause at the beginning of the outlined function for implicit threads: if (<not a master thread>) { ... <thread local copy of var> = <master thread local copy of var>; ... } <sync point>; Checking for a non-master thread is performed by comparing of the address of the thread local variable with the address of the master's variable. Master thread always uses original variables, so you always know the address of the variable in the master thread. Differential Revision: http://reviews.llvm.org/D9026 llvm-svn: 235075
