Binary-code compatibility
Binary-code compatibility (binary compatible or object-code-compatible) is a property of a computer system, meaning that it can run the same executable code, typically machine code for a general-purpose computer CPU, that another computer system can run. Source-code compatibility, on the other hand, means that recompilation or interpretation is necessary before the program can be run on the compatible system.
Symbole (informatique)
En programmation informatique, un symbole est une étiquette apposée sur certains éléments du code objet, du bytecode ou d'un arbre syntaxique abstrait, permettant de les identifier sous cette forme transformée du code source. Un symbole est très proche d'un identificateur du langage source, mais le concept d'identificateur ne recouvre pas totalement le concept de symbole. Le meilleur exemple en est la décoration de nom effectué par les compilateurs C++ qui consiste à trouver un symbole unique pour un identificateur dont le nom est surchargé.
Fat binary
A fat binary (or multiarchitecture binary) is a computer executable program or library which has been expanded (or "fattened") with code native to multiple instruction sets which can consequently be run on multiple processor types. This results in a file larger than a normal one-architecture binary file, thus the name. The usual method of implementation is to include a version of the machine code for each instruction set, preceded by a single entry point with code compatible with all operating systems, which executes a jump to the appropriate section.
