SPIR-V Update

Zig’s compiler team updated the LLVM backend to improve handling of arbitrary‑width integers by extending them to ABI‑sized types when stored in memory.

Does anyone know if there is a zon-parsing CLI tool a la `jq`? I'd like to parse out some fields in a shell script without having to resort to sed (though it works OK). #zig #opensource

ztags (https://codeberg.org/hgrsd/ztags) now supports Mach Nominated Zig versions. If you specify a Mach version (e.g. mach-latest) using `ztags -v`, or if you point at it in `.minimum_zig_version` or `.mach_zig_version` in your `build.zig.zon`, then `ztags` will use the Mach index to resolve the specific Zig build and use those sources to generate tags.

I'm hopeful this will be useful for all of you who are doing some Zig gamedev, which I learnt are many folks on the fediverse!

Thanks to @glitchcake for the suggestion.

Generate ctags-based tags for your Zig project, including Zig sources and stdlib.

Yesss! I’m very excited about this backend. Would be amazing to be able to write shaders in #zig right now using slang

🌗 Zig 編程語言開發日誌：全新的 @bitcast 語義與 LLVM 後端優化
➤ 從位元重解釋到邏輯佈局：Zig 編譯器後端的架構演進
✤ https://ziglang.org/devlog/2026/#2026-06-25
在這篇開發日誌中，Zig 核心貢獻者 Matthew Lugg 詳細介紹了針對 LLVM 後端的重大改進。起初，作者旨在解決非標準寬度整數（如 u4, i13）在記憶體存儲中導致的效能與穩定性問題，改為將其轉換為 ABI 標準尺寸。然而，這一改動觸發了對內置函數 `@bitcast` 的重新定義。作者放棄了過時的記憶體重解釋模型，轉而採用基於「邏輯位元佈局」的新規範。這不僅消除了與大小端（Endianness）相關的非預期行為，還藉助編譯器的「Legalize」階段統一了跨後端的行為，顯著提升了編譯器的健壯性。
+ 身為 Zig 用戶，終於看到對 `@bitcast` 的明確定義了！過去在處理跨平臺大小端差異時確實很困擾，這個改動非常及時。
+ 雖然這只是一個編譯器內部的優化，但將「邏輯位元」與「記憶體佈
