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	f232ebb286	[Caching] Don't parse LLVMArgs in cache replay instance ... `llvm::cl::ParseCommandLineOptions()` is not thread-safe to be called from libSwiftScan so replaying multiple commands in parallel can crash the build system. Since the replay instance is not used for compilation and only need information from command-line arguments to create outputs and diagnostics, ignore LLVMArgs when replaying. rdar://120423882	2024-01-04 13:31:09 -08:00
