Xi Ge	1ba1bd93b2	PrebuiltModules: being resilient to 0-specified build number ... swift-driver passes down an SDK version number with a non-existing build number as 0. The compiler should be resilient to this so we can locate prebuilt module cache. rdar://72230172	2020-12-11 13:50:51 -08:00
Xi Ge	f5477d67af	ModuleInterface: teach the compiler to look into SDK-versioned prebuilt module cache dir ... To support multiple versions of SDKs of the same platform, we should move prebuilt module cache into an SDK-versioned sub-directory and teach the compiler to look into the directory if present. rdar://65488510	2020-07-14 10:40:16 -07:00
