你们说的ABI,Application Binary Interface到底是什么东西? 从这个角度看来,ABI 只是 API 的底层实现,所以多数时候我们才不需要去关心这个问题。 那么当人们提到 ABI 的时候,到底在说什么?以我个人的经验来看,当人们提及 ABI 时,一般主要是在说 Binary-compatible 即二进制兼容性。 什么是二进制兼容性呢?
Does C have a standard ABI? - Stack Overflow C defines no ABI In fact, it bends over backwards to avoid defining an ABI Those people, who like me, who have spent most of their programming lives programming in C on 16 32 64 bit architectures with 8 bit bytes, 2's complement arithmetic and flat address spaces, will usually be quite surprised on reading the convoluted language of the current C standard
大家都在诟病C++的二进制接口(ABI),其它 . . . - 知乎 说白了 ABI 问题只有在 C++ 和 Rust 这类开发速度受编译速度制约极大的语言上才比较显著。 而哪怕是 Haskell 和 Rust,它们对于调整 ABI 相关参数和依赖关系的处理基本上都是工具链自带自动化的,只有 C++ 还在靠 CMake 之类的外部程序处理,导致这个问题更加显著。
Please explain the C++ ABI - Stack Overflow Although the C++ Standard doesn't prescribe any ABI, some actual implementations try hard to preserve ABI compatibility between versions of the toolchain E g with GCC 4 x, it was possible to use a library linked against an older version of libstdc++, from a program that's compiled by a newer toolchain with a newer libstdc++
windows - Why does Windows64 use a different calling convention from . . . The ABI defines stack-unwind metadata that allows exception handling to still work (I assume it works something like GNU Linux x86-64 System V's CFI stuff in eh_frame ) gcc -fomit-frame-pointer has been the default (with optimization enabled) since forever on x86-64, and other compilers (like MSVC) do the same thing
为什么 C++ 标准不明确二进制接口 (ABI) 标准? - 知乎 C其实也没有标准ABI。你把不同机器的库混用,理论上还是undefined behavior,即使这个库不涉及系统调用。 C有的实际上是同一操作系统内的统一ABI,而这种待遇是C的地位决定的。(操作系统多由C或者C++写成,多数实用语言都有办法与C接口对接)
Difference between x86, x32, and x64 architectures? x32 is an ABI for amd64 x86_64 CPUs using 32-bit integers, longs and pointers The idea is to combine the smaller memory and cache footprint from 32-bit data types with the larger register set of x86_64 (Reference: Debian X32 Port page) x32 can provide up to about 30% reduction in memory usage and up to about 40% increase in speed
