--- Comment #8 from Martin Liška <marxin at gcc dot gnu.org> --- I took back what I took back ;) The intermediate format file is created from GCDA file and contains information for multiple source files. So that it does not make sense to "--preserve-paths"/"--hash-filenames". I'll add data_file field to the JSON file and close this issue.
