Artem Chikin	6a12dc0070	[Dependency Scanning] Have the scanner cache answer queries relevant to current search paths only. ... The dependency scanner's cache persists across different queries and answering a subsequent query's module lookup with a module not in the query's search path is not correct. For example, suppose we are looking for a Swift module `Foo` with a set of search paths `SP`. And dependency scanner cache already contains a module `Foo`, for which we found an interface file at location `L`. If `L`∉`SP`, then we cannot re-use the cached entry because we’d be resolving the scanning query to a filesystem location that the current scanning context is not aware of.

Artem Chikin	7e2c8e97fc	[Dependency Scanning] Add ability for -scan-dependencies action to serialize and deserialize dependency scanner cache from a .moddepcache file. ... Using the serialization format added in https://github.com/apple/swift/pull/37585. - Add load/save code for the `-scan-dependencies` code-path. - Add `libSwiftDriver` entry-points to load/store the cache of a given scanner instance.	2021-06-01 14:45:50 -07:00
