Author: abataev Date: Tue Mar 29 03:58:54 2016 New Revision: 264709 URL: http://llvm.org/viewvc/llvm-project?rev=264709&view=rev Log: [OPENMP] Remove extra code transformation.
For better support of some specific GNU extensions some extra transformation of AST nodes were introduced. These transformations are very hard to handle. The code is improved in handling of these extensions by using captured expressions construct.
