Compare upper half of arguments against 0 #4

Values in BPF can only be 32 bit, but arguments are 64 bits long
Currently, we are comparing the lower half of the argument against K, but we need to compare the upper half of the argument against 0

Actually. In thinking about this, this would only be valid if we only compare arguments to numerics. Would there ever be a case where we could compare two arguments directly to each other?

Potentially, yes.
