Thanks to @JensGustedt TIL that C++26 also introduces native support for #C23 checked #integer #arithmetic functions, as defined in the <stdckdint.h> compatibility header. These are peripherally related to the (bleeding edge) #saturation arithmetic functions defined in the C+26 version of the <numeric> header: https://en.cppreference.com/cpp/numeric (You might not find these in your system headers unless you have a seriously up to date #LLVM or #GCC ) @wdtz #languagelawyering

Твой код на Rust компилируется, проходит тесты и является UB. Ты просто об этом не знаешь
Если взять случайный крейт с crates.io и поставить его под Miri, шанс увидеть undefined behavior где-то в зависимостях стремится к единице. Разбираемся, почему: pointer provenance, Stacked Borrows, Tree Borrows и почему noalias в LLVM выключали три раза.

K3 is now natively supported in the Linux Kernel mainline, with key SoC enablement already merged for Linux 7.0!
You can find the K3 DTS files under arch/riscv/boot/dts/spacemit/ in the upstream tree: k3.dtsi, k3-pico-itx.dts.
What’s in Linux 7.0 already (merged upstream):
Basic DeviceTree
Pinctrl, GPIO
Clock, Reset
UART，PMIC (p1)，SDHCI (eMMC) -
My vision for the loop vectorizer in #LLVM has finally crystallized into a first patch! The line of work would have a major impact on optimization result as well as compile time! 🎉

My overall vision for what #LLVM VPlan should ideally be is becoming clearer. It's going to be huge design overhaul, and the work has to be done piece-wise with no unit of work causing regressions. The hard part is convincing all stakeholders to align on the vision, which I cannot explain in natural language sufficiently well.

I need a recap for how to write plugins for #llvm
What is you favourit blog post or book on this topic.
Please share.Yes yes I am reading the docs also

Question for #PL folks:
Is there any usable work taking the typed assembly languages work and layering it on top of #LLVM ? Been quite a while since I read that work, but from what I remember, TAL two had the intersection / union types you'd need for SSA form.
Reason: I will (eventually) need a low-overhead, direct-to-native, and safe way to distribute executable code in a distributed system.

🎉 Oh, joy! Another thrilling day in the life of a programmer chasing bugs in #LLVM #RISC-V while pretending to be Sherlock Holmes. 🔍 The article takes us on a wild ride through benchmarks and code tweaks, but spoiler alert: we still don't really care. 📉

Создание языка программирования дилетантом. Как это?
Идея создать собственный компилятор появилась у меня раньше идеи сделать собственный язык программирования. Помню, ковырялся в исходниках прошивки EV3 контроллера , чтобы сделать его эмуляцию , и в голову пришла идея -- почему бы не сделать что-то такое, но свое? Эмуляция так и не получилась адекватная, но идея написания компилятора или виртуальной машины из головы не уходила.
