From 6119d2522e8a598e50cb2ed05bf523e0ecedad3f Mon Sep 17 00:00:00 2001
From: Nick Clifton <nickc@redhat.com>
Date: Fri, 21 Sep 2007 07:58:03 +0000
Subject: * syms.c (_bfd_stab_section_find_nearest_line): Look at the  
 specific SOM sections for stabs if the regular ones are not found. * som.h
 (struct somdata): Add a line_info field, to be used by som_find_nearest_line.
 * som.c (som_find_nearest_line): Implement using the bfd stabs function
 above.
