Project Stage 3: Beginning and Planning

-

 Introduction

As we move into Project Stage 3, our focus is on integrating everything we’ve worked on so far, ironing out any issues, and making sure our proof-of-concept for the GCC AFMV (Automatic Function Multi-Versioning) feature works seamlessly. This stage is crucial for bringing the project to a successful close.

My Tasks

Update Documentation for GCC IFUNC and FMV:

  • Goal: Improve the current documentation to reflect the latest implementations for different architectures.
  • Plan:
    • Gather detailed information on the current implementations.
    • Expand explanations, add examples, and highlight best practices.
    • Ensure the documentation is comprehensive and easy to understand.

Document the New AFMV Feature:

  • Goal: Create detailed documentation for the newly implemented AFMV feature.
  • Plan:
    • Introduce AFMV, its purpose, and its benefits.
    • Provide clear usage instructions and examples.
    • Highlight how AFMV makes it easier to use processor features without changing the source code.

Planning Steps

Gathering Information:

  • Review the existing documentation and gather all necessary details on the current implementations.

Updating Documentation:

  • Expand the IFUNC and FMV sections with clear explanations, syntax, and examples.
  • Include specific details for different architectures and highlight best practices.

Creating New AFMV Documentation:

  • Explain what AFMV is and why it’s beneficial.
  • Provide step-by-step usage instructions, including command-line options and function attributes.
  • Include examples to show how AFMV works.

Testing and Verification:

  • Test the examples to make sure they work as described.
  • Check that the documentation reflects the latest state of GCC’s implementation and is consistent throughout.

Collaboration and Review:

  • Work closely with team members to ensure all components are integrated smoothly.
  • Review the documentation to make sure it’s clear, complete, and accurate.

Expected Challenges

Ensuring Accuracy:

  • Making sure all documentation updates are accurate and reflect the current state of GCC implementations.

Maintaining Clarity:

  • Presenting complex information in a way that’s easy to understand.

Integration:

  • Ensuring everything integrates smoothly and fixing any conflicts or issues that come up.

Exploring Retro Arcade Days - Simple Yet Challenging Breakout

Lab-2  Introduction  In this lab I got to explore and relive the experience that my dad gained . I wanted to build a game in 6502 assembly language using an online emulator . With the help of online resources and YouTube tutorials , I managed to create a simple game  Concept To experiment , I chose a simple breakout game in which the player has to judge an incoming ball(pixel) , which bounces off of a platform . Player can reposition the platform along the X-axis and the velocity of the ball increase each time it bounces off the platform. Player earns a point each time the ball bounces off the platform . Game ends when the ball hits the bottom of the screen . Development Process Using a 6502 assembly language emulator and a text editor, I began writing the code for my game. I defined variables for the ball's position, velocity, paddle size, score, and collision detection flags. Then, I set up the initial game state, including placing the ball and paddle on the screen. Nex...

Exploring Assembly Language (Lab-1)

Introduction: In the realm of computer programming and analysis, delving into assembly language can be both daunting and exhilarating. As a student at Seneca in computer programming and analysis, I recently embarked on a lab journey exploring the intricacies of assembly language, particularly focusing on the 6502 architecture. In this blog post, I'll share my experiences, discoveries, and insights gained from the lab experiments. Calculating Performance and Modifying Code: In one of the lab experiments, I initially tackled the task of calculating the execution time of a code snippet aimed at filling a bitmapped display with a solid color. After analyzing the code and considering a clock speed of 1 MHz, I calculated the execution time to be approximately 1.321 milliseconds. This involved dissecting the assembly code, understanding the purpose of each instruction, and considering optimization techniques. Here is the original code : lda #$00      ; Load accumulator with lo...

  Exploring Assembly Language on x86_64 and AArch64 Introduction In this lab, we dive into the intricacies of assembler on both x86_64 and AArch64 architectures. We'll explore code examples, disassemble object files, and write simple assembly programs to understand the core differences and functionalities between these architectures. Setting Up First, we unpacked the provided code examples: cd ~ tar xvf /public/spo600-assembler-lab-examples.tgz This created a directory structure under  ~/spo600/examples/ , containing various examples in C and assembly for both architectures. Building and Running C Programs We started with the C programs to establish a baseline: Building the C programs: cd ~/spo600/examples/c make Running the C programs: ./hello ./hello2 ./hello3 Observing the differences: hello.c  uses  printf() . hello2.c  uses  write() . hello3.c  uses  syscall()  directly. Disassembling C Binaries Using  objdump , we disassembled th...
