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
Programming is bridging the gap between what the code does not and what it should do once it’s complete. Yet there is the age-old adage that code is never complete. It only gets close and then you realize greater potential for improvement—which means you start over from that point on. 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
I am coming towards the end of my internship, but without achieving any of my milestones. I am aware of that. I do not want to end my internship without achieving anything. As described in my previous post, I am porting a MicroBlaze Instruction Set Simulator to simulate AEMB processor’s Read more
A trivial do/while loop is an useful technique in C programming to make a multi-statement macro. Consider the following multi-statement C preprocessor macro and if-statement with two branches: #define aemb(x) { do_this(x); do_that(); } if (x > y) aemb(x); // Branch 1 else aemb(y); // Branch 2 Compiling these codes Read more
You might have realized from my previous post that I often bring a lot of emotion to programming. I code best and come up with the best designs when I’m happy and on a roll, but that’s also when I miss the most blatant bugs. When I’m down and struggling, Read more
As mentioned in the previous post, I’ve decided to work on μClinux kernel porting as my project in AESTE. I will briefly introduce it in this post. μClinux (Micro-Controller Linux) is a linux kernel targeted for embedded devices without memory management unit. μClinux was first implemented in DragonBall integrated microprocessor, Motorola Read more
Some people observe that life is an uphill journey and all that matters is The Climb. I believe no such simple analogy for my career here at Aeste. You may remember that my task is to port the AEMB to QEMU and that I have successfully replicated an existing architecture 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
