--- Comment #13 from James Greenhalgh <jgreenhalgh at gcc dot gnu.org> ---
This is a similar case I reduced from the Ubuntu rebuild failures, hitting the
"max" idiom recognition:

---

#pragma GCC push_options
#pragma GCC target("fpu=crypto-neon-fp-armv8")
static void
foo (void)
{
}
#pragma GCC pop_options
float
max_idiom (float x, float y)
{
  return x > y ? x : y;
}

---

Compile with -march=armv7-a -mfloat-abi=hard -mfpu=neon -O2 -ffast-math

Presumably the same root cause.
