* [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. llvm-svn: 321560
* [OPENMP] Fix for PR31428: variable named like directive name modifierAlexey Bataev2016-12-201-3/+3
| | | | | | | | Directive name modifiers in 'if' clause are allowed only for OpenMP 4.5 and higher + in OpenMP 4.5 parsing procedure emits error message if ':' is not found after directive name modifier. llvm-svn: 290175
* [OPENMP] Emit an additional note during analysis of 'if' clause.Alexey Bataev2015-09-151-2/+2
| | | | | | Patch adds emission of additional note for 'if' clauses with name modifiers in case if 'if' clause without name modified was specified or 'if' clause with the same name modifier was specified. llvm-svn: 247706
* [OPENMP 4.1] Parsing/sema analysis for extended format of 'if' clause.Alexey Bataev2015-09-031-0/+14
| | | | | | | | | | | | | | | | | OpenMP 4.1 added special 'directive-name-modifier' to the 'if' clause. Format of 'if' clause is as follows: ``` if([ directive-name-modifier :] scalar-logical-expression) ``` The restriction rules are also changed. 1. If any 'if' clause on the directive includes a 'directive-name-modifier' then all 'if' clauses on the directive must include a 'directive-name-modifier'. 2. At most one 'if' clause without a 'directive-name-modifier' can appear on the directive. 3. At most one 'if' clause with some particular 'directive-name-modifier' can appear on the directive. 'directive-name-modifier' is important for combined directives and allows to separate conditions in 'if' clause for simple sub-directives in combined directive. This 'directive-name-modifier' identifies the sub-directive to which this 'if' clause must be applied. llvm-svn: 246747
* [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).
