How to load memory address without using pseudo-instructions?

Question

I\'m trying to learn MIPS assembly language by myself using MARS simulator.

For didactic reasons I\'m limiting myself to not using pseudo-instructio

Answer 1

You need to refer to a label in the data section in the lui and ori instructions. This works for gnu assembler (as):

    .data
lab1: .byte 0xa1
...
.text
    lui $s0, %hi(lab1)
    ori $s0, %lo(lab1)
    lw  $s2, 0($s1)
...

The %hi and %lo directives tell the linker what is going on, so that it can put the address of the label "lab1" in the machine code.
