There are some instructions in the gcc wiki about how to do this.  The 
gcc wiki is accessible from our home page, gcc.gnu.org.  svn uses a 
built-in diff that doesn't support -p, so you need to tell svn to use an 
external diff program which is a shell script that calls GNU diff.

You could make this conditional on -g3 as a start.  -g2 is the default. 
 See the debug_info_level stuff.

If you are serious about submitting this as a patch, there are a number 
of requirements that must be fulfilled.  We need an FSF GCC copyright 
assignment.  We need test results, for a debug patch, that would include 
both gcc and gdb testsuite results.  The patch needs to be sent to the 
gcc-patches list.  But first you need to get the patch working reliably.
