Xi Ge	aa1e4eec86	sema: check if @_originalDefinedIn attribute has duplicated entries for the same platform name	2019-11-21 17:04:00 -08:00
Xi Ge	7f8c04e0b7	AST: introduce a new attribute @_originallDefinedIn to the AST ... We need this attribute to teach compiler to use a different name from the current module name when generating runtime symbol names for a declaration. This is to serve the workflow of refactoring a symbol from one library to another without breaking the existing ABI. This patch focuses on parsing and serializing the attribute, so @_originallyDefinedIn will show up in AST, swiftinterface files and swiftmodule files. rdar://55268186	2019-11-21 14:25:57 -08:00
