code, but on some machines (RS6000, HPPA, others?) it may fail when |

|

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. */ |
