Bug ID: 112499
Summary: GCC: 14: internal compiler error: output_operand:
invalid expression as operand
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: 141242068 at smail dot nju.edu.cn
Target Milestone: ---
Compiler Explorer: https://gcc.godbolt.org/z/MdacfWqhr
When attempting to compile this program with `gcc-14 -O1`, gcc crashes:
```
#include <stdint.h>
int f(void) {
static uintptr_t a = ((char *)&&l3 - (char *)&&l2) +
((char *)&&l1 - (char *)&&l2);
l1:
l2:
l3:
return a;
}
```
If removing the qualifier `static`, then this crash disappears.
The crash output:
```

operand

--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Or consider
typedef unsigned __INTPTR_TYPE__ uintptr_t;
volatile int v;
int
foo (int x)
{
static uintptr_t a = ((char *)&&l2 - (char *)&&l1) + ((char *)&&l4 - (char
*)&&l3) + ((char *)&&l6 - (char *)&&l5);
void *b[] = { &&l1, &&l2, &&l3, &&l4, &&l5, &&l6 };
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.
