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
Filenamethe file name to adjust.
BaseDirWhen 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).

static

Prepares a path for being written to an AST file by converting it to an absolute path and removing nested '.
