I assume they have the OpenJDK JVM ported at this point so all of JetBrains' products should be working or close to working.

They have to make the claim ‘millions of devices run Java true’. But anyway. A lot of programming languages are going to have to support Arm now. Interpreters for like php and js must be cross-compiled and then most things can work. Like Rust just brought their arm support to the tier 1 support level, see https://github.com/rust-lang/rfcs/pull/2959

And I’ve been getting Rust to work on Apple Silicon. It’s only tier 2 for now, but that’s mostly because there are no CI providers so we can’t automatically run tests for it. I’ve been running them by hand.

Most popular languages have supported Arm for many years already, on Linux (and more recently, some of them on Android and iOS).

(for Linux)

Yep, most things were ported in the first wave of linux arm enthusiasm around the netwinder/ipaq craze 20 years ago.

The "netwinder/ipaq craze 20 years ago" would be 32-bit ARM (AArch32), while AFAIK this new chip is 64-bit ARM (AArch64); everything has to be ported again to this new ISA (though yeah, most things were already ported for Linux on AArch64).

Yep, in the intervening time ARM on Linux became popular enough that doing the required compiler backend work for 64-bit ARM in GCC, LLVM etc by commercial interests was a given, there was eg a big push for ARM on servers from various vendors. MS even ported Windows Server. Eg Hotspot/OpenJDK was ported in 2015.

You also have GraalVM (Oracle), OpenJ9 (IBM) and Corretto (Amazon).

So plenty of enterprise-class JVMs available.

Azul and Microsoft are doing the port.

IIRC, Azul is a hardware vendor for the JVM ... can you please share a public source on this collaboration between Azul & Microsoft?

I don’t think Azul have sold hardware in a few years. Their current offerings, Zing and Zulu, are cross platform JVMs and don’t appear to be sold with any hardware.

Azul was originally a hardware vendor with Java-optimized silicon. They haven't sold hardware AFAIK for probably over a decade.

Yes, they used to have hardware with a ton of cores/cpu's and large amounts of RAM if I remember correctly.

Yeah, it was around the time that thread-level parallelism was getting a lot of love. As I recall, they had some massive number of cores directly connected to each other and garbage collection at least partly in hardware. They got burned for pretty much the same reason a lot of the other custom CPU hardware of the time got burned; if you could just wait for Intel to double performance in a couple years it wasn't really worth going with some one-off design for a temporary advantage.

This is the actual JEP https://openjdk.java.net/jeps/391.

This is an early access build from today https://github.com/microsoft/openjdk-aarch64/releases/tag/16...

Sure, here sparing you the effort to learn how to use Google or whatever search engine you like using.

Thanks for the link but there was no need for you to be patronizing about it.

FWIW, I originally thought your mention of Azul was a typo, so I parsed your comment as "Azure and Microsoft" before I realized the tautology, which was why I posted the question. I didn't realize that Azul had pivoted to be a software-based vendor of the JVM.

I answered like that because of what looked like a snarky comment.

Wouldn't the x86 version run under emulation?
