The structure is - OmpBeginDirective (aka OmpDirectiveSpecification) - Block - optional<OmpEndDirective> (aka optional<OmpDirectiveSpecification>) The OmpBeginDirective and OmpEndDirective are effectively different names for OmpDirectiveSpecification. They exist to allow the semantic analyses to distinguish between the beginning and the ending of a block construct without maintaining additional context. The actual changes are in the parser: parse-tree.h and openmp-parser.cpp in particular. The rest is simply changing the way the directive/clause information is accessed (typically for the simpler). All standalone and block constructs now use OmpDirectiveSpecification to store the directive/clause information.
