Continue from my previous post, LLVM: Compiling FreeRTOS with LLVM (Part 1). Anybody who might have some basic skills in programming, creating Makefiles especially, must be laughing hysterically if they come across and read my previous post in this topic. When I google the phrase “Compiling freertos with llvm” or Read more…
It is about two more weeks before my internship at Aeste ends. Yesterday, I finished my task of cleaning up LLVM floating points instructions and cache instructions. What I did was just hunt all these unwanted instructions inside AEMB target directory files and remove it without damaging the files or Read more…
My recent task is to clean up the instructions from LLVM code. One must wonder why do I need to clean up the instructions, well perhaps the definition of my recent task was not adequately explain here. AEMB is considered as binary compatible to the Xilink Microblaze (Wikipedia link), however Read more…
In LLVM system compiler, there is an option in the command command -mattr called target specific attributes. You may check each target attributes by using this command. llvm-as < /dev/null || llc -march=aemb -mattr=help note that -march=aemb is to select target architecture, in my case, aeMB. A list of attributes Read more…
For the past few weeks, I was given a task by my supervisor. The task sound simple, whenever there NOP (No operation) instruction will be use, LLVM should change it into XOR R0, R0, R0 which basically doing nothing since in aeMB, register zero (R0) always have zero values. NOP Read more…
LLVM is a compiler project which start as a research at University of Illinois and now has grow to become a massive project and involve in both commercial and open source, as well as research. LLVM is licensed under “UIUC” BSD-Style license. Recently, the latest Apples also start using LLVM Read more…
Today, looking at all those codes and documentation of LLVM, it really brings a child out of me. I don’t know why, I feel like I want to play with LEGO toys. When I read todays newspapers report about National Robotics Competition 2011, kids as early as what? 7 years Read more…
As what the title say, working here at Aeste is not a weekend project. It is not an internship place where you have a senior engineer, senior staff, or manager that will tell you what to do or guide you. It is not a place where they will give definitive Read more…
Week 2 Day 1: So, the project decided. Its porting LLVM compiler into AEMB. Time to get the code. Should get svn version or release version? First, lets try the svn version. The error said: svn: Malformed XML: not well-formed (invalid token) Eh? What now? This must not be the Read more…
Hello and good day, As part of task as an intern at Aeste, I was asked by my supervisor to regularly write blog about the task and the experience here. So, this is it. Ahmad Shaiful Amiruddin bin Taher, born in Marang, Terengganu. Final year student, BE(Hons) candidate from Faculty Read more…
