基於 GCC 且支援 MISRA-C 中 單一轉換單元規則之檢查器
為了解決C sizeof pointer 的問題，作者陳志遠 這樣論述：
MISRA-C 是由汽車產業軟體可靠性協會 (MISRA) 所定義的一份關於C 程式語言的編寫規範，它定義了一套規則來增強軟體開發的安全性、可靠性與可移植性。雖然 MISRA-C 起源於汽車產業，但現今已受到航空航天、國防安全、電信、醫療設備等產業的採用。在本篇論文中我們基於 GNU GCC 編譯器架構前端實現了 MISRA-C單翻譯單元標記規則的靜態檢測分析，根據官方文檔範例基準，我們修改後的編譯器能夠準確檢測 MISRA-C 2012 Amendment 1 中全部共 107 條單翻譯單元標記規則。
