Nathan Hawes	f683373116	[ParseableInterface] Respect -track-system-dependencies with -build-module-from-parseable-interface ... Updates the subinvocation that builds the parseable interface to respect the -track-system-dependencies flag of the top-level invocation if present, by including system dependencies in the produced .swiftmodule.	2019-04-03 06:34:29 -07:00

Harlan Haskins	366bbf48b9	[ParseableInterface] Add ‘forwarding modules’ ... A ‘forwarding module’ is a YAML file that’s meant to stand in for a .swiftmodule file and provide an up-to-date description of its dependencies, always using modification times. When a ‘prebuilt module’ is first loaded, we verify that it’s up-to-date by hashing all of its dependencies. Since this is orders of magnitude slower than reading mtimes, we’ll install a `forwarding module` containing the mtimes of the now-validated dependencies.	2019-03-07 11:36:15 -08:00
