Has anyone gotten GDB 3.5 to work under HPUX 7.0 on series 300
machines?

It seemed to work OK under 6.2 (although I hadn't used it much).
Under 7.0 it is incapable of reading (and, probably, writing)
the saved 68000 registers in the inferior process.  Among other
problems, this breaks breakpoints (because the retrieved PC is
garbage).  Plain memory accesses seem to work OK.

I traced this as far as finding that read_inferior_register in hp9k320-dep.c
tries to extract the registers with a ptrace(PT_RUAREA,...) request with a huge
offset.  It seems to me that this is fundamentally wrong -- the registers
are on the stack somewhere, not in the process user area, aren't they?  If
they are in fact stored in kernel space, maybe the problem is just that the
KERNEL_U_ADDR offset has changed again.  A new value (or even better, a
version-independent means of obtaining it) would be much appreciated.
