b label == beq $0,$0,offset

Here is a table of branch instructions. There are additional branch instructions used for subroutine linkage that have been omitted. Some instructions assume 32-bit two's complement data; others assume 32-bit unsigned data. Some instructions don't assume any data format.

The first operand ** s** must be a register.
The second operand

`t`

Some of the pseudoinstructions use the assembler temporary register
(`$at`

,
or register
`$1`

)
in the one or two basic instructions they
are translated into.

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

b | label | branch | beq | s,t,label | branch if s==t | ||

beqz | s,label | branch if s==0 | bge | s,t,label | branch if s>=t | signed | |

bgeu | s,t,label | branch if s>=t | unsigned | bgez | s,label | branch if s>=0 | signed |

bgt | s,t,label | branch if s>t | signed | bgtu | s,t,label | branch if s>t | unsigned |

bgtz | s,label | branch if s>0 | signed | ble | s,t,label | branch if s<=t | signed |

bleu | s,t,label | branch if s<=t | unsigned | blez | s,label | branch if s<=0 | signed |

blt | s,t,label | branch if s<t | signed | bltu | s,t,label | branch if s<t | unsigned |

bltz | s,label | branch if s<0 | signed | bnez | s,label | branch if s != 0 | |

bne | s,t,label | branch if s != t | != means not equal |

What format of data is assumed for the `bne`

(branch not equal)
instruction?
