Note reverting just this rev will cause
long long x[24];
long long y[16];
long long z[8];
void __attribute__((noinline)) foo()
{
for (int i = 0; i < 8; ++i)
{
y[2*i] = x[3*i];
y[2*i + 1] = x[3*i + 1];
z[i] = 1;
}
}
to be miscompiled. This in turn was triggered by the backport of
another fix, 1dbb919d0868319a5503b91049283a189ac1b4ac which I suggest
to revert as well then.
