      Returns true if the specified Language has DWARF register mappings.
      Parameters:
      lang - The Language to test
      Returns:
      true if the language has a DWARF register mapping specified
      Throws:
      IOException - if there was an error in the language LDEF file.

    • getMappingForLang

      public static DWARFRegisterMappings getMappingForLang(Language lang) throws IOException
      Returns a possibly cached DWARFRegisterMappings object for the specified language,
      Parameters:
      lang - Language to get the matching DWARF register mappings for
      Returns:
      DWARFRegisterMappings instance, never null
      Throws:
      IOException - if mapping not found or invalid

    • readMappingForLang

      public static DWARFRegisterMappings readMappingForLang(Language lang) throws IOException

      Throws IOException if the lang does not have a mapping or it is invalid.

      Parameters:
      lang - Language to read the matching DWARF register mappings for
      Returns:
      a new DWARFRegisterMappings instance, created from information read from the DWARF_REGISTER_MAPPING_NAME xml file referenced in the language's LDEF, never null.
      Throws:
      IOException - if there is no DWARF register mapping file associated with the specified Language or if there was an error in the register mapping data.

      Creates a new DWARFRegisterMappings from the data present in the xml element.
      Parameters:
      rootElem - JDom XML element containing the <dwarf> root element of the mapping file.
      lang - The Ghidra Language that the DWARF register mapping applies to
