Bug ID: 99810
Summary: Wrong const evaluation of 64-bit division
Product: gcc
Version: 10.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: gcc at cookiesoft dot de
Target Milestone: ---
Host: x86_64
Target: arm
The following code produces a different result on arm and x86_64:
https://gcc.godbolt.org/z/PPvoscdWa
```
#include <inttypes.h>
#include <stdio.h>
int main() {
printf("%" PRId64 "\n", -62135769600000000 / 1000000);
}
```
ARM: -2006227456 (FFFF FFFF 886B 6600)
X86: -62135769600 (FFFF FFF1 886B 6600)
No single warning is given and I of course would like to see the x86 output,
because that's the right one ;)
