@erichte-ibm could you help with this? This should be trivial for anyone with access to POWER hardware, and it's a blocker for POWER support in `ring`. I've been trying to...

Sadly their pricing is starts at $325/month, and all I need is to run a one-off test on real hardware - the rest can be done in qemu. $325 is...

Ah, indeed it is, and you can pay in smaller increments too. Nice, thanks!

A PR for profiler support on little-endian POWER is up, tested on integricloud: https://github.com/rust-lang/rust/pull/105389

I think the only reasonable option in the short term is to bypass the intrinsics and use inline assembly to get to these instructions. Inline assembly on ARM has been...

[is_aarch64_feature_detected](https://doc.rust-lang.org/std/arch/macro.is_aarch64_feature_detected.html) has been stable since 1.60, so looks like with inline assembly this could be implemented in stable *today,* without waiting on any std or compiler features.

Amazing! That was quick! As for benchmarking, a number of public clouds provide ARM machines and free compute credits upon signup. For example, Google Cloud (full disclosure: they're my employer,...

Also, I have access to an ARM machine, and I could run the benchmarks you specify. Note that the criterion benchmarks in the repository lack black-boxing, which may make them...

I assume the upcoming release also enabled the `use-intrinsics` feature by default, or get rid of it entirely?

> the MSRV policy for this crate requires a major version bump. This is unfortunate because all dependents that re-export the type or expose it in the public API at...
