Xi Ge	7d600eb27a	ABI/API checker: teach the tool to emit diagnostics to serialized source location for decls	2019-10-17 16:31:56 -07:00
Xi Ge	d405fcd8ec	swift-api-digester: teach the tool to directly compare two module interfaces ... We used to use a Json format to capture the ABI/API detail of Swift modules to walk-around module compatibility issues across different compiler versions. Since Swift module now is in stable format, we can compare two swiftinterface files directly without dumping the content into Json format.	2019-06-12 11:16:23 -07:00
Xi Ge	f7406e6c3c	swift-api-digester: diagnose changing of the necessity of new witness table entry as ABI breakage ... Protocol requirements may not necessarily add new entries to the witness table if it's inherited from super protocol. This patch teaches the json dump to include a flag indicating whether a protocol requirement requires new witness table entry and diagnoses the change of such flag as ABI breakages. rdar://47657204	2019-04-01 20:29:44 -07:00
