maybe an option with argument?
-fdump-rtl=detailed -fdump-rtl=classic # same as -fdump-rtl
-fdump-rtl-* (where the star is a path name) is the name of options that enable RTL dumps, e.g. -fdump-rtl-lreg or -fdump-rtl-cse2; "expand" is just a path name, and since the final part of the dump file name is the pass name, the file name gets changed from "foobar.00.rtl" to "foobar.00.expand".
