--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Again what is happening is when expanding INTEGER_CST to const_int, the last
bit of precision is extended to all of the rest. This is how const_int works
and has always worked.
PR 85344 is exactly the same issue:
```
void
foo (void)
{
__asm( "%0" :: "I" ((unsigned char) 0x80));
}
```
Notice `unsigned char` there. 0x80 is then extended to 0xffffff80 as expected
by the rules of RTL and const_int.
