Did a short post comparing LLVM 15 (just released) against older versions using the Burst compiler. TL;DR - its another compile time regression from LLVM 14, which was slower than 13 too! 😲 https://www.duskborn.com/posts/llvm-15-speed/

I wrote a short post about adding a way to skip tests to my single header testing library utest.h https://www.duskborn.com/posts/utest_skip/

I hoisted out a bit of my COVID cancelled EuroLLVM 2020 talk into a blog post - how we made our LLVM pass manager 1.65x faster https://www.duskborn.com/posts/making-legacy-pass-manager-1_65x-faster/

This made me so damn angry, and this is just what we've been 'lucky' enough to capture on film. Those Russian soldiers are the lowest of the low. https://www.bbc.co.uk/news/world-europe-61425025

I used to think people who were into yoga were crackpots - but man alive it has helped me so much with my anxiety during these awful last two years. I'm a total convert!

Switched my C/C++ header subprocess.h to use posix_spawn https://www.duskborn.com/posts/posix_spawn/

First step to supporting LLVM’s opaque pointers done today in Burst - lots and lots of churn left though. Really hope the codegen benefits this is supposed to bring pan out!

The cruelty of Russians in this war is unimaginable. It's easy to say this is Putin's war and dismiss it as one cruel man, but this is a country rotten to its core https://www.bbc.co.uk/news/world-europe-61249158

Does anyone know if it is possible to call posix_spawn or posix_spawnp with a custom PATH? I could hack environ, but that isn't thread safe. Trying to see if I can't move away from fork -> posix_spawn but need to be able to set custom PATH for launching processes!

What a derp!

This is a *fascinating* exploration into the problems with VCS - LLVM moved lots of things to the monorepo (so they all move in lockstep), but now the sheer size of the monorepo and the fact that people changing APIs have to fix a lot more projects is becoming a bottleneck to progress. https://discourse.llvm.org/t/rfc-graduate-circt-to-monorepo/61890/34

Well let’s try this again shall we now…

I missed sooo many optimization opportunities in json.h, fixed some at least! http://www.duskborn.com/1-22x-performance-improvements-in-json-h/

Finally installed ripgrep today - christ this is fucking fast!
