# The exact format for some of this output is not necessarily
|

# ideal, particularly interpreting "p top" requires a fair bit of
|
|
# savvy about gdb's workings and the meaning of the "{}"
|
|
# construct. So the details maybe could be tweaked. But the
|
|
# basic purpose should be maintained, which is (a) users should be
|
|
# able to interact with these variables with some care (they have
|
|
# to know how to interpret them according to their real type,
|
|
# 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, even stabs in ecoff) GCC
|
|
# puts out stProc and related symbols which cause GDB to think
|
|
# it knows the type. GDB probably could be fixed to do
|
|
# better, but for now xfail these tests. Irix5, even though
|
|
# it is ELF, counts as "ecoff" because gcc puts out a .mdebug
|
|
# section even without -g. Personally, I think that is pretty
|
|
# dubious, but maybe dbx requires it.
