Immediate Operand in Branch

If a branch instruction has a second operand, it can be an immediate operand or a register. For example, from the table:

bge

s,t,label

branch if s>=t

signed

Here are examples:

bge    $t1,$t2,spot     # if ( $t1 >= $t2 ) goto spot

bge    $t1,23,spot      # if ( $t1 >= 23  ) goto spot

bge    $t1,-98,spot     # if ( $t1 >= -98 ) goto spot

bge    12,$t1,oops      # WRONG: first op must be a register

bge    $t1,value,oops   # WRONG: second op can't be a symbolic address

Sometimes the mnemonic corresponds to a basic instrucion (for example beq). However if the second operand is an immediate operand then the result is a pseudoinstruction.

bge     $t1,-67,spot     # if ( $t1 >= -67 ) goto spot
