/*
* 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)
* cmpgtu compare greater than unsigned (two registers)
* tstbit0 test bit zero
*
* 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
