* [OPENMP] Support for -fopenmp-simd option with compilation of simd loopsAlexey Bataev2017-12-291-0/+4
| | | | | | | | | only. Added support for -fopenmp-simd option that allows compilation of simd-based constructs without emission of OpenMP runtime calls. llvm-svn: 321560
* [OPENMP] Fix DSA processing for member declaration.Alexey Bataev2017-07-201-2/+2
| | | | | | | | If the member declaration is captured in the OMPCapturedExprDecl, we may loose data-sharing attribute info for this declaration. Patch fixes this bug. llvm-svn: 308629

* Revert "[OPENMP] Allow skip expression after comma in clauses with lists."Alexey Bataev2016-04-011-2/+2
| | | | | | | This reverts commit http://reviews.llvm.org/rL265003. After some thoughts decided to emit errors here. llvm-svn: 265119
* [OPENMP] Allow skip expression after comma in clauses with lists.Alexey Bataev2016-03-311-2/+2
| | | | | | Compatibility fix for better compatibility with the existing software. llvm-svn: 265003
* [OPENMP 4.0] Use 'declare reduction' constructs in 'reduction' clauses.Alexey Bataev2016-03-171-13/+13
| | | | | | | | OpenMP 4.0 allows to define custom reduction operations using '#pragma omp declare reduction' construct. Patch allows to use this custom defined reduction operations in 'reduction' clauses. llvm-svn: 263701
* [OPENMP 4.5] Allow arrays in 'reduction' clause.Alexey Bataev2016-01-261-6/+6
| | | | | | OpenMP 4.5, alogn with array sections, allows to use variables of array type in reductions. llvm-svn: 258804
* [OPENMP] Fixed processing of predetermined data-sharing attributesAlexey Bataev2015-12-101-3/+3
| | | | | | Predetermined data-shared attributes for local variables are now considered as implicit. Also, patch prohibits changin of DSA for static memebers of classes. llvm-svn: 255229
* [Lit Test] Updated 34 Lit tests to be C++11 compatible.Charles Li2015-11-171-0/+5
| | | | | | | Added expected diagnostics new to C++11. Expanded RUN line to: default, C++98/03 and C++11. llvm-svn: 253371
* [OPENMP 4.1] Sema analysis for array sections in 'reduction' clause.Alexey Bataev2015-09-301-18/+19
| | | | | | OpenMP 4.1 allows to use array sections|subscript expressions in 'reduction' clauses. Added sema analysis, updated tests. llvm-svn: 248880
* Allow static local variables specified on data-sharing attribute clauses.Kelvin Li2015-09-151-0/+3

* [OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492)Alexey Bataev2015-05-201-1/+1
| | | | | | | -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] Fix for checking of data-sharing attributes for canonical var decls ↵Alexey Bataev2015-04-161-1/+9
| | | | | | | | | | | only. Currently checks for active data-sharing attributes for variables are performed for found var decls. Instead these checks must be performed for canonical decls of these variables to avoid possible troubles with with the differently qualified re-declarations of the same variable, for example: namespace A { int x; } namespace B { using A::x; } Both A::x and B::x actually reference the same object A::x and this fact must be taken into account during data-sharing attributes analysis. llvm-svn: 235096
* [OPENMP] Codegen for 'reduction' clause in 'parallel' directive.Alexey Bataev2015-04-101-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Emit a code for reduction clause. Next code should be emitted for reductions: static kmp_critical_name lock = { 0 }; void reduce_func(void *lhs[<n>], void *rhs[<n>]) { ... *(Type<i> *)lhs[i] = RedOp<i>(*(Type<i> *)lhs[i], *(Type<i> *)rhs[i]); ... } ... void *RedList[<n>] = {&<RHSExprs>[0], ..., &<RHSExprs>[<n> - 1]}; switch (__kmpc_reduce{_nowait}(<loc>, <gtid>, <n>, sizeof(RedList), RedList, reduce_func, &<lock>)) { case 1: ... <LHSExprs>[i] = RedOp<i>(*<LHSExprs>[i], *<RHSExprs>[i]); ... __kmpc_end_reduce{_nowait}(<loc>, <gtid>, &<lock>); break; case 2: ... Atomic(<LHSExprs>[i] = RedOp<i>(*<LHSExprs>[i], *<RHSExprs>[i])); ... break; default: ; } Reduction variables are a kind of a private variables, they have private copies, but initial values are chosen in accordance with the reduction operation.
