Description

The following construct generates 32-bit values, not sign-extended 64-bit ones (as it is implied).

    # Generator of 32-bit random values which will be sign-extended to fit the target register.
    random_word = situation('random', :size => 32, :sign_extend => true)

    # Input arguments of all instructions listed below are random words.
    set_default_situation 'add'   do random_word end
    set_default_situation 'addi'  do random_word end
    set_default_situation 'addiu' do random_word end
    set_default_situation 'addu'  do random_word end
    set_default_situation 'sub'   do random_word end
    set_default_situation 'subu'  do random_word end
