Linux的32位应用程序移植到64位？ [英] porting linux 32 bit app to 64 bit?

问题描述

我即将端口超大规模的应用到64位， 我注意到，在网上有一些物品演出 这种移植了很多陷阱， 我想知道是否有一个可以协助移植到64位的任何工具，这意味着 在找到需要code的地方被改变....也许与warnnings海合会启用......是不是不够好？有什么好？

i'm about to port very large scale application to 64 Bits, i've noticed in that in the web there some articles which shows many pitfalls of this porting , i wondered if there is any tool which can assist in porting to 64 bit , meaning finding the places in code that needs to be changed.... maybe the gcc with warnnings enabled... is it good enough ? is there anything better ?

编辑：大家好我搜索如果有的话，可能是一个完整的编译器工具，       我知道GCC可以ASIST，但我怀疑它会找到所有未移植的问题，
      将在运行时被发现....也许静态code分析工具，它强调       移植到64位？

Guys i am searching for a tool if any that might be a complete to the compiler, i know GCC can asist , but i doubt it will find all un portable problems that
will be discovered in run-time....maybe static code analysis tool that emphasize porting to 64 bits ?

感谢

推荐答案

一个很好的工具，叫做的grep ;-) DO

A good tool is called grep ;-) do

grep -nH -e '\<int\>\|\<short\>\|\<long\>' *

和通过适当的替换这些基本整数类型的所有裸露的用途：

and replace all bare uses of these basic integer types by the proper one:

• 在数组的下标应为size_t
• 指针类型转换应该是 uintptr_t形式
• 在指针的差异应该是 prtdiff_t
• 类型与宽度N的假设 应 uintN_t

• array indices should be size_t
• pointer casts should be uintptr_t
• pointer differences should be prtdiff_t
• types with an assumption of width N should be uintN_t

等等，我可能忘记了一些。 然后的 GCC 上会告诉你所有的警告。你也可以使用铛为编译器它提供了更多的诊断。

and so on, I probably forgot some. Then gcc with all warnings on will tell you. You could also use clang as a compiler it gives even more diagnostics.
