Steven Wu	52671e1a6a	[Caching] Improve swift caching related tests ... Improve caching related tests to make them faster and test the situation closer to what actually happens during explicit module build. Most noticable changes are: * Avoid swift stdlib dependency during the tests to save time * Use dependency scanner output to construct test cases * Update old test cases that try to simulate caching from file system inputs to using only CAS inputs.	2024-01-28 22:06:59 -08:00
Steven Wu	1325dd6a50	[Caching] Fix frontend cache replay for batch mode ... Teach swift-frontend to correctly replay cache when using batch-mode/primary-file. Currently, the cache replay logic will try to look up cache key for all the inputs and only replay if all lookups are successful. In batch-mode, not all inputs are producing outputs, which causes lookup for those keys to be a miss and causing a false miss for the compilation.	2023-12-01 09:59:38 -08:00
