--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Another testcase:
struct a {
char b;
char c[];
} ;
struct a d;
int main() {
return d.c[0x40000000] || d.c[1];
}
In GCC 10 (and before) fold would produce:
return ((unsigned char) BIT_FIELD_REF <MEM <struct a> [(void *)&d], 8, 16> &
255) != 0;
Which is a bit interesting because the d.c[0x40000000] part is left off.
