# This test has six arms.  The first three arms accept normal output:
# no synthetic methods; synthetic methods before user methods;
# synthetic methods after user methods.
#
# The next two arms accept "foobar__Fi.0::Local" instead of "Local".
# This is a bug.  It happens in various places with various versions of
# gcc and gdb and various debugging types.
#
# The last arm accepts the user methods in duplicate.  This bug happens
# with gcc 3.3.2 -gdwarf-2, and has been fixed in gcc HEAD 2004-01-22.
