Alexis Laferrière	552d3a4984	[Sema] Restrict reexported SPIs to modules with an export_as relationship ... @_exported exports SPIs only when the exported module defines export_as pointing to the exporter module. Other reexports do not reexport SPIs. This is to prevent SPI reexporting to get out of hands with the wide reexports of the Objective-C world. rdar://102335473	2022-11-14 13:17:55 -08:00
Alexis Laferrière	c0abde01a2	[Sema] @_exported imports export @_spi decls too ... Enable transitive imports of all SPI groups through @_exported imports. This brings to SPI the same behavior that we have for API. ``` // Module A @_spi(S) public func foo() {} // Module B @_exported import A // Module C @_spi(S) import B foo() // SPI imported through the reexport of A from B ``` rdar://101566534	2022-11-10 16:46:14 -08:00
