--- Comment #1 from Krzysztof Parzyszek <kparzysz at quicinc.com> ---
The C4 instructions negate the result of the comparison (Pd = !cmp(...)).

The J4_cmpOP_C_jumpnv instructions do: if (R.new OP other-val) == C then jump
...
For example, J4_cmplt_f_jumpnv_nt will branch if (Ns8.new < Rt32) is false, or,
if (Rt32 > Ns8.new) is false, i.e. if !cmp.gt(Rt32, Ns8.new).
