Assembler Lab Catch up

After getting some feedback from Professor Tyler regarding my issue I was able to complete the assembly lab. You can find the loop from 0 to 9 here. The loop through 00 to 30 is here.

Completing the aarch64 assembly took me a bit longer than the x86_64 portion of the lab, this is possibly due to the time in between labs, and having to relearn some of what I figured out.

Here are some of the differences:

Description	x86_64	aarch64
value 10 into register 15	mov $10,%r15	mov r15,10
add 0x30 to register 15	add 0x30,%r15	add x15,x15,0x30
go to label if !=	jne label	bne label

There were some other differences that caused some issues. I forgot to include “mov x0,1“, which caused my “Hello, world!” to print only once to the screen instead of 10 times during my initial phase of creating the program. I believe this is equivalent to the following command in x86_64 movq $1,%rdi.

Overall I found the x86_64 assembly easier (maybe because I did those first and was used to its layout), but like most programming languages, the logic is practically the same; it is a matter of learning the syntax in the different environment. I find myself having to take time to write a simple hello world program, but hoping with more practice, I will be able to write more verbose programs in assembly.
