Machine code can easily be decoded back to its corresponding assembly language source code because assembly language forms a one-to-one mapping to machine code. [17] The assembly language decoding method is called disassembly. Machine code may be decoded back to its corresponding high-level language under two conditions:
An assembler program functions by converting low-level assembly code into a conventional machine code that is readable by the CPU. The purpose of assembly language, like other coding languages, is to make the programming process more user-friendly than programming in machine language.
Machine code is the form in which code that can be directly executed is stored on a computer. It consists of machine language instructions, stored in memory, that perform operations such as moving values in and out of memory locations, arithmetic and Boolean logic, and testing values and, based on the test, either executing the next instruction in memory or executing an instruction at another ...
The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language (e.g. assembly language, object code, or machine code) to create an executable program. [1] [2]: p1 [3] There are many different types of compilers which produce output in different useful forms.
[20] [21] [22] The utility could translate Intel 8080 and Zilog Z80 assembly source code (with Zilog/Mostek mnemonics) into .ASM source code for the Intel 8086 (in a format only compatible with SCP's cross-assembler ASM86 for CP/M-80), but supported only a subset of opcodes, registers and modes, and often still required significant manual ...
Formerly, LLVM relied on the system assembler, or one provided by a toolchain, to translate assembly into machine code. LLVM MC's integrated assembler supports most LLVM targets, including IA-32, x86-64, ARM, and ARM64. For some targets, including the various MIPS instruction sets, integrated assembly support is usable but still in the beta stage.
The code can be read and written by a programmer. To run on a computer it must be converted into a machine readable form, a process called assembly. [4] The language is specific to a particular processor family and environment. [2]
In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions.
