随着应用软件的不断积累，二进制代码兼容已经成为微处理器能否具有生命力的关键问题。
Accumulation of software has made binary code compatibility a critical issue for the success of a processor.
关于与其他选项的兼容性和与GCC 3.0以前的版本生成的二进制代码的调用兼容性，请参考GCC手册获得详细情况。
Refer to the GCC manual for details concerning the compatibility with other options and for call-compatibility with binary code generated by pre-3.0 versions of GCC.
例如，在SLES8系统中使用glibc版本2.2.5编译的二进制代码，将可以在SLES9系统中使用glibc版本2.3运行，因为2.3版本是向后兼容的。
For example, a binary that was compiled on a SLES8 system with a version of glibc at 2.2.5 will also run on a SLES9 system with a glibc version at 2.3 since the 2.3 version is backward compatible.
