I have been a long time gtags/global/ggtags.el use and love it. When I use ggtags.el to find all the locations where a particular symbol is referenced, I wish it were possible to ask to be shown all the places where the symbol is being "modified" (written to.)
Ideally, I wish either GRTAGS (or elsewhere) the following entries can be generated:
Symbol Read/Write function file_name line_number
we can then, with some simple arg flag (^u for example?) only search for symbol where it is being modified, possibly restricting it to just the current function an/or current file.
How hard would this be to do? I am willing to do some of the work if guided. Also, when I use
gtags --sqlite3, the GRTAGS file seems essentially empty. (I have built gtags with --with-sqlilte).
