They are auto-generated and any edits to these files can be overwritten and lost if their origin files are modified. I'd lost edits to these auto generated files many time because they are the ones that "tags" or "cscope" will jump to when searching for symbols. There really isn't any reason for them to be writable, so the fact that you are getting an error trying to open them for writing is a hint that you are doing, or going to do, the wrong thing and the read-only nature of the file is preventing you from going down the wrong path.
