ARM ABI学习总结
ABI是Application Binary Interface的缩写，关于ABI的介绍，可以参考维基百科：http://en.wikipedia.org/wiki/Application_binary_interface
摘自：ABI
What is the ABI for the ARM Architecture? Is it the same as the ARM EABI?
The ABI for the ARM Architecture is a standard developed by ARM and its partners that explains how compilers, assemblers, linkers, and other similar tools should generate object files and executable files.
Tools that correctly implement the ABI for the ARM Architecture can interoperate; i.e., object files built with one toolchain can be combined with object files built with another toolchain if both compilers use the ABI for the ARM Architecture and provided that the code compiled observes certain conventions.
CodeSourcery was an active participant in the design of the ABI for the ARM Architecture. (In fact, the C++ ABI used by ARM is derived from the Itanium C++ ABI co-designed by CodeSourcery.) CodeSourcery continues to work with ARM, Ltd. to validate interoperability between Sourcery CodeBench and ARM's proprietary tools.
The "ARM EABI" is an informal name for the ABI for the ARM Architecture.
