Author: mwu Date: Thu Aug 2 21:21:25 2018 New Revision: 338808 URL: http://llvm.org/viewvc/llvm-project?rev=338808&view=rev Log: [libclang 3/8] Add support for AttributedType
Summary: This patch adds support to the libclang API for identifying AttributedTypes in CXTypes and reading the modified type that the type points to. Currently AttributedTypes are skipped. This patch continues to skip AttributedTypes by default, but adds a parsing option to CXTranslationUnit to include AttributedTypes. This patch depends on D49066 since it also adds a CXType. Testing will be added in another patch which depends on this one.
