planckforth: Bootstrapping a Forth interpreter from hand-written tiny ELF binary
Hacker News
This Hacker News post discusses planckforth, a project that demonstrates bootstrapping a Forth interpreter starting from a minimal, hand-written ELF binary. It explores the process of building a compiler and interpreter from scratch.
社群進一步探討了手寫二進位碼的可行性。雖然現代 x86 指令集因定址模式複雜而難以記憶,但資深工程師回憶起 6502 處理器時代,手動將彙編指令轉換為十六進位碼(Hand-assembly)是相當普遍且實用的技能。對於當時的開發者而言,記住常用的十幾條指令碼並不困難,甚至比處理繁瑣的編輯器與組譯器工具鏈更有效率。這種「肉眼反組譯」的能力在沉浸於底層環境幾天後便能自然養成。
