Blog about the Xojo programming language and IDE
Code generation is one of the last steps of the compiler. This is where the compiler emits actual machine code for the IR that was previously created.
This is the eighth post in our Compiler series. Other posts:
The last post covered optimization in general. In this post you’ll look at a specific optimization called “loop unrolling”.
This is the seventh post in our Compiler series. Other posts:
As the old joke goes, “There are 10 types of people, those that understand how binary numbers work and those that don’t.” Let’s get you into the “understand” group.
Comments closedAn optimizer “improves” the IR, but that can mean a lot of different things. Improve could mean “run faster” or “use less memory”. Or perhaps you want to optimize for memory access time because CPUs are so fast it is sometimes more efficient to repeatedly calculate something rather than calculate it once, store it and access it later.
This is the sixth post in our Compiler series. Previous posts:
Once the front end has done its work its time for the back end components to take over.
This is the fifth in our compiler series and the first on the back end. We covered the parts of the compiler that are called the front end in these posts:
Now that the Semantic Analyzer has verified that the code is actually correct and created syntax trees, it’s time to talk about IR generation.
This is the fourth post in our Compiler series. Other posts:
The Semantic Analyzer is the real heart of the compiler. Its job is to validate code and figure out what the code actually means. Essentially it validates that the code is semantically correct.
This is the third post in our Compiler series. Previous posts:
Comments closedThe Xojo community is vibrant and active, with all kinds of clever, open-source software being created for iOS, desktop, web and Raspberry Pi. By my latest count, there are at least 80 open-source projects for Xojo on GitHub and other places!
Comments closedThere are about 80 Xojo-related open-source projects that I am tracking on the Xojo Dev Center: Open-Source Projects. I often have people ask me how they can make their own cool libraries and projects available on GitHub, so here’s a short tutorial.
Comments closedOf course you want an iMac Pro! But do you really need one for your development work? Most of the iMac Pro videos and reviews seem to focus on video and audio editing, which are certainly tasks that make use of the many cores that are available (8-18).
But software development is also a Pro task. What benefits does an iMac Pro bring to a software developer?
Typically most people will opt for a computer that probably has four cores such as found in the i5 and i7 series. These are used in the popular Macbook Pro and iMac models, for example. Four cores sure sounds like a lot so why would a developer need more?
