261304-assemblysim's Introduction

Assignment Information: http://myweb.cmu.ac.th/sansanee.a/ComputerArchitecture/Y2022/Project1.htm

How to run: This will compile the assembly to machine code and save the compiled file then show the result from simulator. python .\main.py .\programs\example.s

If you want to run on a specific part:

Examples on how to use assembler: python .\assembler.py .\tests\files\t2.s
Examples on how to use simulator: python .\simulator.py .\tests\files\test_sim_example.bin

Unit Test: This will run all unit tests. python -m unittest discover

261304-assemblysim's Issues

No exception when typo instructions

This may case memory leak.

chain address Assembly ?

ถ้าแบบเรียก เป็น ทอดๆ แบบนี้อะ beq มันจะกระโดดผิด ( ซึ่งมันอาจจะห้ามเขียนยังงี้?)

Simulator Unit Test doesn't work due to different tab spacing

Comparing the output from terminal with example output doesn't work. Due to different tab space setting across our IDEs. The tab space for the expected testcase which is supposed to be 8 spaces is always changing. FUCK TAB.

This issue is not urgent. We can fuck it for now.

Exception should not rise when there is no label

Instruction expected rise when there is no label

test/t5.s

.fill 55

result:

No exception when label is number

Label should not be number and instruction should except when argument not match

test case

1 add 0 1  label should not be number
1 add 0

result:

Use forward slash or other method for path

For compatibility across OSes. \ don't work in Linux

hello reg 0 must be alway ZERO

Offset field should accept negative integer - assembler

Breaking testcase

lw 0 0 -1

Output

Traceback (most recent call last):

Exception: I_ins immediate is not int

Expected output:

should pass, no exception
