GCC C ++名称修改参考 [英] GCC C++ Name mangling reference

问题描述

环顾四周，我主要看到有关拆解C ++符号而不是如何处理它们的问题.是的，可以使用-S选项在某些包含要整改的符号的伪代码上调用g++，然后检查生成的程序集，但是我无法找到有关GCC的良好参考或规范.名字改头换面.我能找到的最接近的东西是 http://www.int0x80.gr/papers/name_mangling.pdf ，但似乎并没有涵盖诸如名称模板实例化如何被篡改或_Z3fooIN3BarEE3FooIXT_EEv为什么会转换为Foo<Bar> foo<Bar>()的事情(尽管我可以看到，但是IXT_EE到底是什么?为什么在此_Z之后没有N?这甚至意味着什么?).

Looking around, I see mostly questions about demangling C++ symbols rather than how to mangle them. Yes, one could invoke g++, using the -S option, on some dummy code containing the symbols to be mangled, and then examine the resulting assembly, but I haven't been able to find a good reference or specification on GCC's name mangling. The closest thing I could find was at http://www.int0x80.gr/papers/name_mangling.pdf, but it doesn't seem to cover things like how names template instantiations are mangled or why _Z3fooIN3BarEE3FooIXT_EEv would translate into Foo<Bar> foo<Bar>() (though I can kind of see how, but what the hell is IXT_EE? Why is there no N after the _Z in this one? What's that even mean?).

推荐答案

从gcc来源引用(

Quote from gcc's sources(https://github.com/gcc-mirror/gcc/blob/master/gcc/cp/mangle.c):

此文件根据IA64 C ++实现对C ++名称的处理 ABI规范.

This file implements mangling of C++ names according to the IA64 C++ ABI specification.

这是此规范中的规则: https://itanium-cxx-abi.github.io/cxx -abi/abi.html#mangling

And here is the rules from this specification: https://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling
