/* This testcase is part of GDB, the GNU debugger.
Update years in copyright notice for the GDB files. Two modifications: 1. The addition of 2013 to the copyright year range for every file; 2. The use of a single year range, instead of potentially multiple year ranges, as approved by the FSF.

/* 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. */
