It's not uncommon for machines to have a branchless idiom for generating the value of a condition. For instance, in x86:

    cmp price, 100
    setg reg
    movzx reg, reg
    lea reg, [reg + reg*4 + 5]

    cmp price, 100
    cmc
    salc
    and al, 5
    add al, 5

Get out of here with your undocumented opcodes!
