--- Comment #7 from Jakub Jelinek ---
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.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70549 --- Comment #6 from Christophe Lyon --- I've reproduced it too with our latest 4.8, and I confirm it compiles OK with the very first commit in branch 4.9. Since you switched to 4.9, I will not investigate more.

But then again, the "insn does not satisfy its constraints" is a fairly common ICE. your GCC reports "gcc (Debian/Linaro 4.8.4-1) 4.8.4" Therefore I'd report it to Linaro. Christophe, can you help with this?
