2017-05-18Fix the location of "missing ';'" suggestions after annotation tokens.Richard Smith1-7/+7
We were incorrectly setting PrevTokLocation to the first token in the annotation token instead of the last when consuming it. To fix this without adding a complex switch to the hot path through ConsumeToken, we now have a ConsumeAnnotationToken function for consuming annotation tokens in addition to the other Consume*Token special case functions. llvm-svn: 303372

2017-02-07P0091R3: Implement basic parsing support for C++17 deduction-guides.Richard Smith1-3/+4
We model deduction-guides as functions with a new kind of name that identifies the template whose deduction they guide; the bulk of this patch is adding the new name kind. This gives us a clean way to attach an extensible list of guides to a class template in a way that doesn't require any special handling in AST files etc (and we're going to need these functions we come to performing deduction). llvm-svn: 294266

[OpenMP] Initial implementation of parse and sema for composite pragma 'distribute parallel for' This patch is an initial implementation for #distribute parallel for. The main differences that affect other pragmas are: The implementation of 'distribute parallel for' requires blocking of the associated loop, where blocks are "distributed" to different teams and iterations within each block are scheduled to parallel threads within each team. To implement blocking, sema creates two additional worksharing directive fields that are used to pass the team assigned block lower and upper bounds through the outlined function resulting from 'parallel'. In this way, scheduling for 'for' to threads can use those bounds. As a consequence of blocking, the stride of 'distribute' is not 1 but it is equal to the blocking size. This is returned by the runtime and sema prepares a DistIncrExpr variable to hold that value. As a consequence of blocking, the global upper bound (EnsureUpperBound) expression of the 'for' is not the original loop upper bound (e.g. in for(i = 0 ; i < N; i++) this is 'N') but it is the team-assigned block upper bound. Sema creates a new expression holding the calculation of the actual upper bound for 'for' as UB = min(UB, PrevUB), where UB is the loop upper bound, and PrevUB is the team-assigned block upper bound. llvm-svn: 273884

2016-04-12[OPENMP 4.0] Support for 'linear' clause in 'declare simd' directive.Alexey Bataev1-13/+27
The linear clause declares one or more list items to be private to a SIMD lane and to have a linear relationship with respect to the iteration space of a loop. 'linear' '(' <linear-list> [ ':' <linear-step> ] ')' When a linear-step expression is specified in a linear clause it must be either a constant integer expression or an integer-typed parameter that is specified in a uniform clause on the directive. 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: 266056
2016-04-12[OPENMP 4.0] Support for 'aligned' clause in 'declare simd' directive.Alexey Bataev1-60/+77
The aligned clause declares that the object to which each list item points is aligned to the number of bytes expressed in the optional parameter of the aligned clause. 'aligned' '(' <argument-list> [ ':' <alignment> ] ')' The optional parameter of the aligned clause, alignment, must be a constant positive integer expression. If no optional parameter is specified, implementation-defined default alignments for SIMD instructions on the target platforms are assumed. 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: 266052

2016-04-06[OPENMP] Parsing and Sema support for 'omp declare target' directiveDmitry Polukhin1-0/+56
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

2016-03-30[OPENMP 4.0] Initial support for '#pragma omp declare simd' directive.Alexey Bataev1-2/+55
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.

2016-03-17[OPENMP 4.0] Use 'declare reduction' constructs in 'reduction' clauses.Alexey Bataev1-5/+16

2016-03-03[OPENMP 4.0] Initial support for 'omp declare reduction' construct.Alexey Bataev1-4/+260
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.
