After finally managing to port an architecture i thought i’d share the steps as there isnt a clear or simple guide on adding your own backend to LLVM. It should be noted that at this time of writing the LLVM documentation at llvm.org is outdated (also mentioned on their website). Read more
Finally managed to compile LLVM and clang for microblaze. I find using configure –target= or -target doesnt work while using –enable-targets=”mblaze” worked. I found the documentation to be very poor on this and does not mention anything about the other options available in configure such as using –enable-targets. I also Read more
First day at aeste, tried to set up workplace but had to leave the PC to download the eclipse addon overnight. Will compile the tools and check eclipse tomorrow.
I was being informed that my blog posts were too technical until a point that it bored the readers. I felt pity for my supervisor, because he needs to read through all my dull blog posts before publishing them. The reason that I prefer to blog technical stuff is that Read more
Processes can be classified as either I/O-bound or processor-bound. As the name suggests, the former is a process where much of the time is spent in waiting for relatively slow I/O operations to complete. For instance, a process taking input for a word processor will be I/O-bound as it spends most of its time Read more
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
Multitasking operating system is a software that offers interleave execution of more than one process. It is capable of executing several processes concurrently and therefore giving an illusion of parallelism in the view of user abstraction. Multitasking operating systems come in two flavors: cooperative multitasking and preemptive multitasking. In cooperative multitasking, a process does not stop running until it is 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
AEMB is a family of highly-rated open-source embedded microprocessor core. All the programs for AEMB have to run in a simulation environment, because the core has not yet been implemented in silicone chip. Recently, one of the interns is assigned with the porting of AEMB for QEMU. With the QEMU ported Read more
