Or consider
typedef unsigned __INTPTR_TYPE__ uintptr_t;
volatile int v;
int
foo (int x)
{
static uintptr_t a = ((char *)& - (char *)&) + ((char *)& - (char
*)&) + ((char *)& - (char *)&);
void *b[] = { &, &, &, &, &, & };
l1:
++v;
l2:
++v;
l3:
++v;
l4:
++v;
l5:
++v;
l6:
++v;
if (x >= 0 && x <= 5)
{
x += 42;
goto *b[x - 42];
}
return a;
}
That is even older.
r0-79351-g7771bb621aad43c7d0e21ccec4922dd3beac9cb6
still used to reject that:
error: initializer element is not computable at load time
r0-79390-g7ffb5e78794b6d8f8094d7c928e6f0e94b62cad6
already accepts but assembler doesn't handle that:
pr112499-2.s:58: Error: invalid operands (*ABS* and .text sections) for `-'
pr112499-2.s:58: Error: invalid operands (*ABS* and .text sections) for `-'
pr112499-2.s:58: Error: invalid operands (.text and .text sections) for `+'
.quad .L3-.L6-.L4-.L2+.L7+.L5
Guess we can only accept a subtraction of 2 labels, not addition of 2 labels or
something more complex.
