You can append a -all to get more info, e.g. -fdump-rtl-ce1-all will emit more info than -fdump-rtl-ce1. This will only emit info where the optimization pass has hooks to dump debugging info. If you need more info than that, you should be stepping through the code in gdb We have gdb macros in the .gdbinit file that you can use to pretty print rtl, etc. The pr macro will pretty print an rtl pointer.
