[gdb/cli] Honour 'print pretty' when printing result of finish command
Consider this testcase:
...
struct s {
int a;
int b;
};
struct s foo ()
{
struct s r;
r.a = 1;
r.b = 2;
return r;
}
int
main (void)
{
struct s v;
v = foo ();
return v.a + v.b;
}
...
When we compile it with -g, load the exec with gdb, and run till the end of foo,
we can print r:
...
(gdb) p r
$1 = {a = 1, b = 2}
...
and by setting pretty printing to on, we can get the fields of r printed each
on its own line:
...
(gdb) set print pretty
(gdb) p r
$2 = {
a = 1,
b = 2
}
...
However, when we finish foo, the printed function result value is not using
the pretty printing setting:
...
(gdb) finish
Run till exit from #0 foo () at test.c:11
0x00000000004004c1 in main () at test.c:18
18 v = foo ();
Value returned is $3 = {a = 1, b = 2}
...
This patch fixes that by using get_user_print_options instead of
get_no_prettyformat_print_options in print_return_value_1, which gives us:
...
(gdb) finish
Run till exit from #0 foo () at test.c:11
0x00000000004004c1 in main () at test.c:18
18 v = foo ();
Value returned is $2 = {
a = 1,
b = 2
}
...
Build & reg-tested on x86_64.
