The great leap toward 64-bit computing and the maintenance of backward compatibility with 32-bit and 16-bit software enabled the x86 architecture to become an extremely flexible platform today, with x86 chips being utilized from small low-power systems (for example, Intel Quark and Intel Atom) to fast gaming desktop computers (for example ...
x86 assembly language is a family of low-level programming languages that are used to produce object code for the x86 class of processors. These languages provide backward compatibility with CPUs dating back to the Intel 8008 microprocessor, introduced in April 1972.
The Netwide Assembler (NASM) is an assembler and disassembler for the Intel x86 architecture. It can be used to write 16-bit, 32-bit and 64-bit programs. It is considered one of the most popular assemblers for Linux and x86 chips. [3] It was originally written by Simon Tatham with assistance from Julian Hall.
Meaning Notes BOUND: 62 /r: Check array index against bounds: raises software interrupt 5 if test fails ENTER: C8 iw ib: Enter stack frame: Modifies stack for entry to procedure for high level language. Takes two operands: the amount of storage to be allocated on the stack and the nesting level of the procedure. INSB/INSW: 6C Input from port to ...
IA-32 is the first incarnation of x86 that supports 32-bit computing; [4] as a result, the "IA-32" term may be used as a metonym to refer to all x86 versions that support 32-bit computing. [5] [6] Within various programming language directives, IA-32 is still sometimes referred to
Tachyon Software LLC markets the Tachyon Assembler Workbench which runs on Windows, Linux/x86, Linux for S/390 and zSeries, AIX and Solaris. [35] GNU Assembler (gas) is part of the GNU Compiler Collection (gcc) for Linux on OS/390 and IBM Z. This assembler has a unique syntax that is incompatible with other assemblers for IBM architectures.
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.
