Calling conventions for C++ compilers and OS in pdf

The present manual describes differences between various C++ compilers that affect binary compatibility, such as data storage, function calling conventions, and name mangling. The function calling methods, name mangling schemes, etc. are described in detail for each compiler.

The purposes of publishing this information are:

• Point out incompatibilities between compilers.
• Make new compilers compatible with old ones.
• Solve compatibility problems between function libraries produced by different compilers.
• Facilitate linking different programming languages together.
• Facilitate the making of assembly subroutines that are compatible with multiple compilers and multiple operating systems.
• Solve compatibility problems for data stored in binary files.
• Facilitate the construction of debugging, profiling and disassembly tools.
• Facilitate the construction of object file conversion utilities.
• Provoke compiler vendors to use open standards.
• Inspire future standardization.
