# since gdb doesn't know the type), but (b) users should be able
# to detect that gdb does not know the type, rather than just
# being told they are ints or functions returning int like old
# versions of gdb used to do.
# On alpha (and other ecoff systems) the native compilers put
# out debugging info for non-aggregate return values of functions
# even without -g, which should be accepted.
# Irix5, even though it is ELF, counts as "ecoff" because it
# encapsulates ecoff debugging info in a .mdebug section.
# Irix6 gcc emits no debug info at all for static functions and
# variables, so all tests involving statics fail.
