Duncan P. N. Exon Smith	3ee43adfb2	Basic: Add native support for stdin to SourceManager and FileManager ... Add support for stdin to SourceManager and FileManager. Adds FileManager::getSTDIN, which adds a FileEntryRef for `<stdin>` and reads the MemoryBuffer, which is stored as `FileEntry::Content`. Eventually the other buffers in `ContentCache` will sink to here as well -- we probably usually want to load/save a MemoryBuffer eagerly -- but it's happening early for stdin to get rid of CompilerInstance::InitializeSourceManager's final call to `SourceManager::overrideFileContents`. clang/test/CXX/modules-ts/dcl.dcl/dcl.module/dcl.module.export/p1.cpp relies on building a module from stdin; supporting that requires setting ContentCache::BufferOverridden.

Duncan P. N. Exon Smith	0978c83e6f	Basic: Initialize FileEntry's fields inline, almost NFC ... Initialize most of FileEntry's fields inline (all the ones that can be). The only functionality change is to avoid leaving some fields uninitialized.	2020-12-10 13:57:21 -08:00
Duncan P. N. Exon Smith	23ed570af1	Split out llvm/Support/FileSystem/UniqueID.h and clang/Basic/FileEntry.h, NFC ... Split `FileEntry` and `FileEntryRef` out into a new file `clang/Basic/FileEntry.h`. This allows current users of a forward-declared `FileEntry` to transition to `FileEntryRef` without adding more includers of `FileManager.h`. Also split `UniqueID` out to llvm/Support/FileSystem/UniqueID.h, so `FileEntry.h` doesn't need to include all of `FileSystem.h` for just that type.
