=========
|
|
|
|
This library implements the Code Sourcery C++ ABI, as documented here:
|
|
|
|
http://www.codesourcery.com/public/cxx-abi/abi.html
|
|
|
|
It is intended to sit below an STL implementation, and provide features required by the compiler for implementation of the C++ language.
|
|
|
|
Current Status
|
|
--------------
|
|
|
|
At present, the library implements the following parts of the ABI specification:
|
|
|
|
- RTTI classes and support for the dynamic_cast<> operator.
|
|
- Exception handling.
|
|
- Thread-safe initializers.
|
|
|
|
Exception handling requires the assistance of a stack-unwinding library
|
|
implementing the low-level parts of the ABI. Either libgcc_s or libunwind
|
|
should work for this purpose.
|
|
|
|
The library depends on various libc features, but does not depend on any C++
|
|
features not implemented purely in the compiler or in the library itself.
|
|
|
|
Supported Platforms
|
|
-------------------
|
|
|
|
This code was initially developed on FreeBSD/x86, and has also been tested on FreeBSD/x86-64. It should work on other platforms that use the Code Sourcery ABI, for example Itanium, however this is untested.
|
|
|
|
This library also supports the ARM EH ABI.
