This option matches MSVC options and does the path substitution for the file references in the preprocessor macros, debug and coverage information. This option acts as a clang's ``-ffile-prefix-map=value`` and with some known differences in behavior with original CL's option that do not affect the functionality: * nomalizes the macro prefix map pathes -- removes `./` and uses the target's platform-specific path separator character when exanding the preprocessor macros -- ``-ffile-reproducible`` (but not the debug and coverage prefix maps). * does not require ``/experimental:deterministic`` as by MSVC. It needed for removing a hostname from a mangling hash gen, but clang-cl does not use a hostname when generates the hashes. Known issues: * does not remap the pathes within PCH/PCM files.
