adjustFilenameForRelocatableAST()

static const char * adjustFilenameForRelocatableAST ( const char *  Filename, StringRef  BaseDir  )

static

Adjusts the given filename to only write out the portion of the filename that is not part of the system root directory.

Parameters

Filename	the file name to adjust.
BaseDir	When non-NULL, the PCH file is a relocatable AST file and the returned filename will be adjusted by this root directory.

Returns

either the original filename (if it needs no adjustment) or the adjusted filename (which points into the Filename parameter).
