* [OPENMP] Do not allow to use threadprivate or thread local variables as loop ↵Alexey Bataev2015-12-251-0/+2
| | | | | | | | | iteration variables. According to OpenMP the loop iteration variable may not appear in a threadprivate directive. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@256417 91177308-0d34-0410-b5e6-96231b3b80d8
* [OPENMP 4.1] Allow references in init expression for loop-based constructs.Alexey Bataev2015-08-061-8/+8
| | | | | | | OpenMP 4.1 allows to use variables with reference types in private clauses and, therefore, in init expressions of the cannonical loop forms. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@244209 91177308-0d34-0410-b5e6-96231b3b80d8
* [OPENMP] Fixed detection of canonical loops with random access iterators.Alexey Bataev2015-07-161-1/+1
| | | | | | | Add handling of iterators with copy/move constructors with default arguments + converting template constructors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@242382 91177308-0d34-0410-b5e6-96231b3b80d8
* [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).

| | | | | | lop based directives. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@237102 91177308-0d34-0410-b5e6-96231b3b80d8
* [OPENMP] Allow to use global variables as lcv in loop-based directives.Alexey Bataev2015-04-301-2/+0
| | | | | | | | For proper codegen we need to capture variable in the OpenMP region. In loop-based directives loop control variables are private by default and they must be captured in this region. There was a problem with capturing of globals, used as lcv, as they was not marked as private by default. Differential Revision: http://reviews.llvm.org/D9336 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@236201 91177308-0d34-0410-b5e6-96231b3b80d8
* [OPENMP] Temporary fix for processing of global variables in loops.Alexey Bataev2014-11-141-0/+18
| | | | | | | Currently there is a bug in processing of global variables used as loop control variables in 'omp for/simd' constructs: these globals must be captured as private variables, but currently they are nor. This is a temporary bug fix for this problem until the correct solution is prepared. If a global var used as lcv without explicit mark as a private/linear/lastprivate the error message is emitted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@221970 91177308-0d34-0410-b5e6-96231b3b80d8
* [OPENMP] Loop collapsing and codegen for 'omp simd' directive.Alexander Musman2014-10-011-1/+15
| | | | | | | | | | | | | | | This patch implements collapsing of the loops (in particular, in presense of clause 'collapse'). It calculates number of iterations N and expressions nesessary to calculate the nested loops counters values based on new iteration variable (that goes from 0 to N-1) in Sema. It also adds Codegen for 'omp simd', which uses (and tests) this feature.

* [OPENMP] Loop canonical form analysis (Sema)Alexander Musman2014-06-031-0/+574
This patch implements semantic analysis to make sure that the loop is in OpenMP canonical form. This is the form required for 'omp simd', 'omp for' and other loop pragmas.
