Ask for a dump using the -blocks switch and post-process the dump file 
with the attached script.

$ gcc -fdump-tree-all-blocks file.c
$ dump2dot file.c.XXXt.yyy

It generates a graphviz file with the flow graph of the function.  The 
script is fairly simplistic and will not handle more than one function 
too gracefully, but that should be easy to change.
