+ * Compound compare and jump instructions
+ * Here is a primer to understand the tag names
+ *
+ * Comparison
+ *      cmpeqi   compare equal to an immediate
+ *      cmpgti   compare greater than an immediate
+ *      cmpgtiu  compare greater than an unsigned immediate
+ *      cmpeqn1  compare equal to negative 1
+ *      cmpgtn1  compare greater than negative 1
+ *      cmpeq    compare equal (two registers)
+ *
+ * Condition
+ *      tp0      p0 is true     p0 = cmp.eq(r0,#5); if (p0.new) jump:nt address
+ *      fp0      p0 is false    p0 = cmp.eq(r0,#5); if (!p0.new) jump:nt address
+ *      tp1      p1 is true     p1 = cmp.eq(r0,#5); if (p1.new) jump:nt address
+ *      fp1      p1 is false    p1 = cmp.eq(r0,#5); if (!p1.new) jump:nt address
+ *
+ * Prediction (not modelled in qemu)
+ *      _nt      not taken
+ *      _t       taken
