It's on: JagJam, the gamejam for the Atari Jaguar, started today. If you'd like to code a game for one of the most unique systems of the 90s that initially awed id Software's John Carmack, provoked Sega to rush their 32X to market and even got Sony briefly taking notice while they were finishing their Playstation, this is your chance! 😎 Thanks to Songbird Productions and @ctrlaltrees for being part of this year's JagJam again. And don't worry if you don't have that much time: JagJam runs until the end of October, so you've got six months to go. Looking forward to your entries! 🥳 Please spread the word if this whole thing is something you'd like to see getting more attention. Cheers!

Das war wegen den #RISC Prozessoren System bedingt und war daher nicht nur von der Software abhängig.

🌗 在1960年代的UNIVAC電腦上運行Minecraft伺服器及更多應用
➤ 穿越時空：復古硬體上的現代奇蹟
✤ https://farlow.dev/2026/04/17/running-a-minecraft-server-and-more-on-a-1960s-univac-computer
本文作者與團隊成功在1960年代，僅有90KB記憶體及250KHz時脈的UNIVAC 1219B老式電腦上，運行了包括Minecraft伺服器、NES模擬器、OCaml程式、網頁伺服器及各種經典遊戲等驚人應用。這項成就克服了UNIVAC獨特的18位元架構、一補數算術和分區記憶體等嚴峻技術挑戰。關鍵突破在於放棄直接編譯，轉而透過在UNIVAC上實現RISC-V模擬器，再將現代C程式碼編譯成RISC-V指令集，最終在模擬層上執行。儘管模擬會帶來效能損耗，但這種方法不僅簡化了開發複雜性，更有效利用了有限的記憶體空間，展現了在極端硬體限制下推動技術邊界的不懈熱情。
+ 這真是太不可思議了！在這麼老的機器上跑

🌘 追蹤 LLVM RISC-V 後端 25% 效能退化的排查過程
➤ 從效能數據分析到編譯器優化邏輯的深度修復
✤ https://blog.kaving.me/blog/tracking-down-a-25-regression-on-llvm-risc-v/
本文記錄了作者排查 LLVM RISC-V 後端效能退化問題的過程。透過對比 GCC 與 LLVM 生成的組合語言，作者發現 LLVM 無意間將浮點運算提升為雙精度（fdiv.d），導致運算延遲大幅增加（從 19 週期的 fdiv.s 變為 33 週期的 fdiv.d）。深入分析後，發現近期一個旨在優化轉型邏輯的 LLVM 提交，意外破壞了下游的縮減優化機制（narrowing optimization）。作者透過擴展範圍分析（range analysis）修正了 `getMinimumFPType` 邏輯，成功恢復了原本的優化效果，解決了約 24% 的效能衰退問題。
+ 這種透過 `llvm-mca` 驗證組合語言效能的方式非常專業，對於解決複雜的編譯器

Tracking down a 25% Regression on LLVM RISC-V

Similar to the previous post, this post covers my analysis of a benchmark on RISC-V targets. Unlike the previous post, I was able to land a patch to eliminate the performance gap to GCC (for this benchmark)!

🎉 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. 📉
