The following program tries to copy words from the address in register $a0 to the address in register $a1, counting the number of words copied in register $v0. The program stops copying when it finds a word equal to 0. You do not have to preserve the contents of registers $v1, $a0, and $a1. This terminating word should be copied but not counted.
addi $v0, $zero, 0 #Initialize count
loop: lw $v1, 0($a0) # Read next word from source
sw $v1, 0($a1) # write to destination
addi $a0, $a0, 4 # Advance pointer to next source
addi $a1, $a1, 4 # Advance pointer to next destination
beq $v1, $zero, loop #loop if word copied != zero
There are multiple bugs in this MIPS program; fix them and turn in a bug - free version.
and one more problem:
show the singele MIPS instruction or minimal sequence of instructions for this C statement:
b = 25 | a;
Anssume that a corresponds to register $t0 and b corresponds to register $t1.
Thank you for help
