Bug ID: 94670

Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: doko at debian dot org
Target Milestone: ---
Seen on the gcc-8, gcc-9 branches and trunk, worked around with -O2.
$ cat hb-set.ii
struct f {
long operator[](int i) { return c.d[i]; }
struct {
long d[sizeof 0];
} c;
};
template <typename e> struct o {
int g;
e h;
e &operator[](int i) {
e *j;
unsigned b = i;
j = &h;
return j[b];
}
};
int k, m;
unsigned l;
struct n {
struct C {
int t() {
int p = l = sizeof(d);
for (unsigned b = 0; b < l; b++) {
long q = d[b], d = q;
k = __builtin_popcountl(d);
p += k;
}
return p;
}
f d;
};
o<C> pages;
int m_fn1() {
unsigned a = pages.g;
for (unsigned b = 0; b < a; b++)
m += pages[b].t();
return m;
}
} r;
void s() { r.m_fn1(); }
