Mnemonic | Operands | Description | signed or unsigned? |
---|---|---|---|

seq | d,s,t | set d if s==t | |

sge | d,s,t | set d if s>=t | signed |

sgeu | d,s,t | set d if s>=t | unsigned |

sgt | d,s,t | set d if s> t | signed |

sgtu | d,s,t | set d if s> t | unsigned |

sle | d,s,t | set d if s<=t | signed |

sleu | d,s,t | set d if s<=t | unsigned |

slt | d,s,t | set d if s< t | signed |

slti | d,s,Imm | set d if s< Imm | signed |

sltu | d,s,t | set d if s< t | unsigned |

sltiu | d,s,Imm | set d if s< Imm | unsigned |

sne | d,s,t | set d if s != t |

Here
is a table of set instructions.
Most of them are pseudoinstructions.
The `t`

operand can be
an immediate operand.
The `Imm`

operand must
be an immediate operand.

The extended assembler outputs the correct basic instructions depending on the mnemonic and the operands. Sometimes there are several ways in which the same basic instructions can be specified.

Some of the instructions are intended for integers expressed in unsigned binary, other instructions are for integers in two's complement, and for others it makes no difference.

Do you think that the following two pseudoinstructions translate into the same basic instructions?

`sltu $t4,$v0,45`

and`sltui $t4,$v0,45`
