Status update, September 2022 September 15, 2022 on Drew DeVault's blog

I have COVID-19 and I am halfway through my stockpile of tissues, so I’m gonna keep this status update brief.

In Hare news, I finally put the last pieces into place to make cross compiling as easy as possible. Nothing else particularly world-shattering going on here. I have a bunch of new stuff in my patch queue to review once I’m feeling better, however, including bigint stuff — a big step towards TLS support. Unrelatedly, TLS support seems to be progressing upstream in qbe. (See what I did there?)

powerctl is a small new project I wrote to configure power management states on Linux. I’m pretty pleased with how it turned out. It makes for a good case study on Hare for systems programming.

In Helios, I have been refactoring the hell out of everything, rewriting or redesigning large parts of it from scratch. Presently this means that a lot of the functionality which was previously present was removed, and is being slowly re-introduced with substantial changes. The key is reworking these features to take better consideration of the full object lifecycle — creating, copying, and destroying capabilities. An improvement which ended up being useful in the course of this work is adding address space IDs (PCIDs on x86_64), which is going to offer a substantial performance boost down the line.

Alright, time for a nap. Bye!

Update 2023-01-31: Russ Cox of the Go team reached out to us to address this problem. After some discussion, an acceptable plan was worked out. The Go team is working on deploying an update to the “go” tool to add a -reuse flag, which should substantially re…
