Steven Wu	4125e8c3cd	[ScanDependencies] Get accurate macro dependency ... Build an accurate macro dependency for swift caching. Specifically, do not include not used macro plugins into the dependency, which might cause false negatives for cache hits. This also builds the foundation for future improvement when dependency scanning will determine the macro plugin to load and swift-frontend do not need to redo the work. rdar://127116512	2024-06-27 10:45:14 -07:00
Steven Wu	daa1065304	[Caching] Preliminary simple macro support for caching ... Preliminary caching support for macro: * Inserting the plugin into the CASFS * Lookup plugin via physical file system For future better support, we should teach dependency scanner to resolve macros and return the resolved plugins to swift-frontend. rdar://121873571	2024-04-08 09:41:05 -07:00
