The following MIPS branching pseudo instruction
bge $s0, $s1, Label # branch to Label if $s0 is greater or equal $s1
will be translated to these two native instructions by the MIPS assembler:
slt $at, $s0, $s1
[a] $at, [b], Label
Fill for [a] and [b]?
Please explain aswell
Homework Answers
Answer:
[a] = beq
[b] = $zero
Explanation:
In MIPS, some operations can be performed with help of other instructions. The most common operations are unified in pseudo-instructions — they can be coded in assembly language, and assembler will expand them to real instructions.
Therefore, the expansion of bge $s0, $s1, Label # branch to Label if $s0 is greater or equal $s1 is
slt $at, $s0, $s1
beq $at, $zero, Label
Please give thumbsup, if you like it. Thanks.

MIPS ISA does not have all the instruction that one would wish for, for a good reason, the main “customer” is not a human programmer but a compiler. Pseudo-instructions can be added to an ISA to simplify the programming by humans. These are essentially mnemonics for a sequence of ISA instructions.
