-// #71602 reported a simple array comparison just generating a loop.
-// This was originally fixed by ensuring it generates a single bcmp,
-// but we now generate it as a load+icmp instead. `is_zero_slice` was
-// tweaked to still test the case of comparison against a slice,
-// and `is_zero_array` tests the new array-specific behaviour.
-// The optimization was then extended to short slice-to-array comparisons,
-// so the first test here now has a long slice to still get the bcmp.
