This is the only other Tier-1 platform apart from Linux on Intel x86-64. Given Arm Linux’S astonishingly wide adoption, this bodes well for Rust.

Can you elaborate? I don’t know much about Rust’s tiers of support, so I googled and found https://doc.rust-lang.org/nightly/rustc/platform-support.htm..., and it has a larger list. Is that something different?

Uh both MacOS and Windows have tier-1 support on x86-64

Maybe what they meant was to say just about the hardware arch support...

Actually, not the core team, as the core team doesn't do decisions like this. This was decided jointly by the compiler, infra and release teams.

You're right!

The core team helped set the context and begin the process of understanding what Tiers meant and what the gaps were for AArch64 Linux.

Ultimately the approvals had to come from those 3 teams. I was particularly pleased with how well structured the process was!

Meanwhile Intel profits are sinking, Ryzen is thriving, and RISC-V is chugging along.

Awesome! This is superb news for a wide range of usages, such as AArch64 based Linux systems, Raspberry Pi hardware, Apple silicon, and more.

Yeah great, that makes Rust look like a good embedded language.

What about AVR though? I have been following the rust-avr fork for litterally years now, and it just got merged. It's still highly unreliable though, and Harvard architecture related bugs can make you pull your hairs.

If the rust community is going to promote embedded rust, it would be good to invest some effort in a wider spectrum of architectures. The language itself should be mature enough to take a break. Expanding the architecture range would be very welcome by a lot of people.

Effort is not fungible, we are an open source project, not a business. We can only do what we can convince people to spend their time doing. The folks who work on the language just aren’t the same people who would implement a new LLVM backend. We would love mature Rust support on as many platforms as possible, but it’s non-trivial.

In this case, ARM stepped up themselves to help make this happen. If other vendors want to help us make Rust great on their platform, we’d love to have their support.

I'm quite sure they'd be happy to have you submit patches to add better support.

I hope that some day ppc64{le,be} get there soon. Would love to use openpower based completly open systems. Atleast for the time-being only OpenPower matches or beats the performance profiles of x86_64.
