An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
In addition to the binary application code, the executables may contain headers and tables with relocation and fixup information as well as various kinds of meta data. Among those formats listed, the ones in most common use are PE (on Microsoft Windows ), ELF (on Linux and most other versions of Unix ), Mach-O (on macOS and iOS ) and MZ (on DOS ).
UPX (Ultimate Packer for eXecutables) is a free and open source executable packer supporting a number of file formats from different operating systems. [ 3 ] [ 4 ] Compression
Nachos can run any MIPS binary, assuming that it restricts itself to only making system calls that Nachos understands. In Unix, "a.out" files are stored in "coff" format. Nachos requires that executables be in the simpler "Noff" format. To convert binaries of one format to the other, use the coff2noff program. [5]
Linux was the first operating system kernel to run the x86-64 architecture in long mode, starting with the 2.4 version in 2001 (preceding the hardware's availability). [91] [92] Linux also provides backward compatibility for running 32-bit executables. This permits programs to be recompiled into long mode while retaining the use of 32-bit programs.
It supports Intel-style assembly language on the IA-32 and x86-64 computer architectures. It claims high speed, size optimizations, operating system (OS) portability, and macro abilities. [2] [3] It is a low-level assembler [3] and intentionally uses very few command-line options. It is free and open-source software.
GoboLinux is a Linux distribution whose most prominent feature is a reorganization of the traditional Linux file system.Rather than following the Filesystem Hierarchy Standard like most Unix-like systems, each program in a GoboLinux system has its own subdirectory tree, where all of its files (including settings specific for that program) may be found.
