--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Well, 4.9 did not fix this, on the reduced:
struct A { float x; float y; };
A a, b, c;
int d, e;
A bar ();
void foo (A, A);
inline A operator/ (A, A p2) { if (p2.x) return a; }
struct B { A dval; };
int baz (A, B, A, int);
void
test ()
{
B q;
A f, g, h, k;
h.x = 1.0;
f = h;
struct A i, j = f;
do {
i = bar ();
g = i / j;
foo (g, c);
int l = baz (k, q, b, e);
if (l)
goto cleanup;
j = i;
} while (d);
cleanup:;
}
with -O2 -fPIC -fno-schedule-insns -mno-lra I can still reproduce it even with
r219720; GCC 5 is fine, because -mno-lra has been removed in r219734.
GCC 4.9 is not upstream supported either, this note is mainly for those still
maintaining 4.8 or 4.9 aarch64 branches.
