If you look in gcc/gcc/gdbinit.in, you will see some gdb
macros which call some internal debugging functions.
pt calls debug_tree
pr calls debug_rtx
ptc prints the tree code of a node
In terms of dumping stuff to a file, you might want
to look at the gcc manual:
http://gcc.gnu.org/onlinedocs/gcc-3.0.1/gcc_17.html#SEC171
There are some flags:
-dR, -dr, -di and others that allow you to dump RTL to a file.
