At Xojo we did the hard work of creating a framework with an API that manages the nuances, intricacies, and subtle yet important differences between 7 different platforms (macOS, Windows, Linux, web, Raspberry Pi, iOS and soon, Android) so you can focus on what makes your application unique. We have been doing it for over 20 years.

Every once in a while we get a question or post like this one that wonders why a loop might turn into an infinite loop or why it doesn’t behave as expected and stop when the loop reaches the limit.

An 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:

Viruses continue to be a big problem on Windows. As a result, anti-virus software can be a bit over-zealous about detecting what it believes to be apps that have viruses embedded within them. We have had reports over the years that apps made with Xojo are sometimes falsely identified as being infected with a virus. This sometimes occurs because the 32-bit Xojo compiler puts executable code in a location where the anti-virus software doesn’t expect to find it. We’ve seen this occur even when users are debugging apps from the IDE. Fortunately in that case, there’s a fairly easy solution.

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:
- LLVM Everywhere
- Compilers 101 – Overview and Lexer
- Compilers 102 – Parser
- Compilers 103 – Semantic Analyzer
- Compilers 104 – IR Generation
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:

2017 has been a good year for Xojo! We hit some bumps but we’re ending the year with the much-awaited Xojo 64-bit IDE released in Xojo 2017r3.
Though we didn’t have a XDC in 2017, we’re gearing up for XDC 2018 in Denver in April. This is the longest between conferences in many years and we’re seeing an increase in early registrations. If you are planning on attending, please register soon. We have sold out before!

At XDC 2016 there was a lot of interest in our Compiler session and LLVM. I’ve summarized a bit about LLVM in an earlier post, but to take things further, we put together this series of blog posts on compilers.
These will all be at a high-level. None of these posts are going to teach you how to write a compiler. The goal of these posts is for you to have a basic understanding of the components of a compiler and how they all work together to create a native app.
This is the second post in our ongoing series on compilers. I recommend that you first read Compilers 101 – Overview and Lexer before continuing.

Some of the most recent features added to Xojo, including iOS, 64-bit apps, and Raspberry Pi have been made possible by LLVM. Read on to learn more about it.
