See below.
Here
is the complete main().
.globl main
.text
main: # object1 = new object();
li $v0,9 # allocate 32 bytes
li $a0,32 #
syscall # $v0 = address
sw $v0,object1 #
la $t0,print # initialize jump table
sw $t0,0($v0) #
la $t0,read #
sw $t0,4($v0) #
# object1.read();
lw $a0,object1 # get address of object1
lw $t0,4($a0) # get address of read method
jalr $t0 # call the method
# object1.print();
lw $a0,object1 # get address of first object
lw $t0,0($a0) # get address of print method
jalr $t0 # call the method
li $v0,10 # return to OS
syscall
.data
object1: .word 0
object2: .word 0
The program needs the code for
the print() and the read() method.
Where would a compiler of an OO language find the code for the methods?
