Landed fixes in GCC & Clang for [expr.static.cast]/8 wrong-code bugs when investigating a V8 bug related to it. Previously:

enum Flag : bool { kNo, kYes };
static_cast<Flag>(2); // kNo in GCC ❌, kYes in Clang ✅
static_cast<Flag>(0.5); // kNo in GCC and Clang ❌

It's now much, much easier to test LLVM buildbot changes locally (e.g. new workers/builders or other config changes) discourse.llvm.org/t/psa-recent-i… - let me know if you have problems and as noted in the thread, further tweaks/tips to the docs are appreciated!

ICYMI, there's been a big discussion on evolving MLIR project governance, defining a technical charter, and restructuring the codebase. If you're an MLIR user/developer, be sure to fill in the just-posted survey intended to help further guide this debate discourse.llvm.org/t/survey-mlir-…

CfP for the RISC-V Devroom at FOSDEM 2025:

Deadline: 1st December 2024. Don't wait until the last minute! @risc_v @fosdem

We had a great time in the Bay Area last week, delivering talks at both the RISC-V Summit and the LLVM Developers’ Meeting, and of course catching up in person with many RISC-V LLVM collaborators. We’re looking forward to the next ones already!

Wonderful to meet so many new people and catch up with others at both the RISC-V Summit and LLVM Developers' Meeting this week. If only the two events didn't overlap...

As always, many people I didn't get a chance to chat to - hopefully next time!

Our colleague @asbradbury wrote about Igalia teaming up with RISE (the RISC-V Software Ecosystem project) to improve #LLVM Continuous Integration, thus ensuring more reliable and efficient development for the ecosystem. Read more about it on RISE’s blog! riseproject.dev/2024/10/15/wor…

Wow! The Nov 7-8 Soft @risc_v Systems Workshop has 250 registrants.

We’re extending the talk submission deadline to Oct 20 (anywhere), notifications Oct 21.

All welcome.

You have a cross-compiled build tree of ~10GiB or so you want to run tests against "natively" under qemu-system. How best to access it?

TL;DR: just pay the upfront cost mkfs.ext4/mksquashfs, recouped by faster access times

The slides from the tutorial I gave earlier this year at the RISC-V Summit Europe: Supporting custom RISC-V extensions in LLVM are now online

Some notes on how I set up Arch on a remote server (typically as a builder that roughly matches my local environment) muxup.com/arch-linux-on-…

And now added a teeny bit of JS so a quadruple-click on a large code block selects it all.

Igalia is such a force across all the major browser engines. I wish more companies realized that fixing a problem or adding a feature to the web could be as simple as hiring Igalia.

If you have been wondering about the x87 optimization introduced in FEX release 2408, I wrote something about this. p.ocmatos.com/blog/fex-x87-s…

Wonder what I was doing in Helsinki last month? Here's a blog post from my colleagues at @igalia talking about some interesting things coming up in JS standardization blogs.igalia.com/compilers/2024…

If you're interested in how the LLVM GSoC participants are getting on, check out the virtual, informal, GSoC midterm conference tomorrow 23rd July discourse.llvm.org/t/gsoc-2024-mi…

Some updates to pwr github.com/muxup/pwr:
* Fetch retry logic and set custom user agent
* Typing annotations
* Add fetcher/extractor for GitHub discussions pages (no RSS?!)
* Add fetcher/extractor for groups.​io topic pages as used by e.g. RISC-V working groups (no RSS?!)

And now a fetcher for forum.nim-lang.​org, an undocumented "test-fetcher" action, and properly setting the number of replies in all of the forum fetchers. I think I'm feature complete as far as I'm concerned at this point.

Ever wondered what the extended instruction encoding looks like on Vivante GPUs? cgit.freedesktop.org/mesa/mesa/comm…
