On x86_64-linux with -O2 -g gcc creates invalid DW_AT_upper_bound:
struct S
{
int *a;
int b;
int **c;
int d;
};
void foo (struct S *);
void bar (struct S *);
int
baz (void)
{
struct S s;
foo (&s);
{
int a[s.b];
int *c[s.d];
s.a = a;
s.c = c;
bar (&s);
}
return 0;
}
.long .LLST1 # DW_AT_upper_bound
.long .LLST3 # DW_AT_upper_bound
Note that loclistptr isn't valid for DW_AT_upper_bound attribute, unlike
DW_AT_location it can be a constant or reference, like DW_AT_location it can be
a block (exprloc) and unlike DW_AT_location it can't be loclistptr.
Discovered this by readelf -wo cc1 >/dev/null complaining about holes in
.debug_loc.

* dwarf2out.c (add_bound_info): If a decl bound doesn't have decl_die,
fallthrough to default handling, just with want_address 0 instead of 2.
For single element lists, add_AT_loc directly, otherwise create an
artificial variable DIE and stick location list to it.
* gcc.dg/debug/dwarf2/pr43237.c: New test.
