--- Comment #7 from Martin Sebor ---
On GCC 10.0 trunk, f0 is not unrolled anymore (as it is with GCC 9.2). g0 is
still not unrolled. All other functions are still unrolled as before in GCC
10.

--- Comment #5 from Richard Biener ---
So in addition to the unrolling heuristics we can see that at -O2 PRE defeats
memcpy detection for g0 and f0 (but PRE does nothing to g1 and f1). At -O3
PRE avoids this transform because of heuristics
