Here are the 2 files, in their entirety. However, since they are clones of break.c and break.exp, I just added, for your viewing pleasure, a diff between break.exp and sepdebug.exp. 2003-11-12 Elena Zannoni * gdb.base/sepdebug.exp: New test for separate debug info files. * gdb.base/sepdebug.c: New source file for the above. * lib/gdb.exp (separate_debug_filename): New procedure.
