Now, let me just say this upfront: if you’ve been using the old toolchain (which we lovingly refer to as “GCC 8”), you might be a little bit confused about why we need something new and fancy like this. Well, bro, it all comes down to one simple fact GCC 8 is outdated and doesn’t support some of the newer features that are available on ARM-A devices these days.

Don’t Worry! The good over at Arm have come up with a brand new toolchain specifically designed for AArch64 bare metal targets, and it’s absolutely amazing. Let me tell you all about it!

First how do we get our hands on this magical toolchain? Well, lucky for us, Arm has made it super easy to download and install. All we need to do is head over to their website (https://developer.arm.com/tools-and-software/open-source-software/gnu-toolchain/downloads) and grab the latest version of GCC for AArch64 Linux targets or AArch64 ELF bare metal targets, depending on what we’re working with.

Once we have that downloaded, it’s time to extract the archive into a folder called “Backend” (because who doesn’t love a good pun?). We now have access to all of the amazing features and functionality that come with this new toolchain.

But wait there’s more! Not only does GCC Arm Toolchain for AArch64 Bare Metal Targets support newer features, but it also has some pretty awesome optimizations built in. For example, we can now use the “-O3” flag to enable aggressive optimization and get even better performance out of our code.

And if that wasn’t enough, this new toolchain is also incredibly easy to use! All we need to do is run a simple script called “Compile-ARM64.sh” (which you can find in the Backend folder) and it will automatically compile all of our source files into an executable binary file that we can load onto our ARM-A device using a tool like QEMU or U-Boot.

And if you’re still not convinced, just take a look at some of these amazing statistics:

– Up to 50% faster compilation times compared to previous versions of GCC!
– Up to 20% better performance out of the box thanks to aggressive optimization and improved code generation techniques.
– And best of all it’s completely free and open source, so you can use it for any project without having to worry about licensing fees or other ***** legal issues.

So what are you waiting for? Head over to Arm’s website today and download the GCC Arm Toolchain for AArch64 Bare Metal Targets! Your bare metal development experience will never be the same again.
