In a nutshell, it's not possible for GDB to determine when the address

of a function or the address of the function's stub/trampoline should

be passed.
|

|

So, to avoid GDB lossage in the common case, we perform calls through the
|
||||
various function pointers and compare the return values. For the HPPA
|
||||
at least, this allows the common case to work.
|
||||
|
||||
If one wants to try something more complicated, pass the address of
|
||||
a function accepting a "double" as one of its first 4 arguments. Call
|
||||
that function indirectly through the function pointer. This would fail

on the HPPA. */
