/* This used to simply compare the function pointer arguments with
|
|
known values for func_val1 and func_val2. Doing so is valid ANSI
|
|
code, but on some machines (RS6000, HPPA, others?) it may fail when
|
|
called directly by GDB.
|
|
|
|
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. */
