static Optional<llvm::sys::fs::UniqueID> getActualFileUID

(

const FileEntry *

File

)

[static]

Retrieve the inode for the given file entry, if possible.

This routine involves a system call, and therefore should only be used in non-performance-critical code.

static bool MoveUpIncludeHierarchy	(	std::pair< FileID, unsigned > &	Loc,

	)		[static]

Given a decomposed source location, move it up the include/expansion stack to the parent source location. If this is possible, return the decomposed version of the parent in Loc and return false. If Loc is the top-level entry, return true and don't modify it.
