因此,它们是 ISA 相关的,即为一种 ISA 生成的汇编程序通常与其他 ISA 不兼容。 “GNU Assembler”2 具(或 as)是一个汇编器,能够将以多种汇编语言编写的程序翻译成各自 ISA 的机器语言。在本书中,我们将使用as工具将RV32IM汇编程序翻译为机器语言程序。以下命令行说明了如何调用 riscv64-unknown-elf-as 工...

A compiler is distinguished from an assembler by the fact that each input statement does not, in general, correspond to a single machine instruction or fixed sequence of instructions. A compiler may support such features as automatic allocation of variables, arbitrary arithmetic expressions, control ...
Programming languages can be implemented with compilers, assemblers, and interpretters. A compiler converts high level source code into executable object code (also called binary code or machine code). An assembler converts assembly language source code into executable object code. An interpretter tra...

macro instruction, a mnemonic (such as “READ”) for which the assembler substitutes a series of simpler mnemonics. The resulting machine language programs, however, are specific to one type of computer and will usually not run on a computer with a different type of central processing unit (...
An assembler translates the mnemonic-based instructions to machine code, according to the ISA's specifications. Microcode and primitives Some processors use microcode to carry out their operations. Microcode is integrated into the microarchitecture and is considered an even lower-level language than ...
The first actual implementation of an assembler, a tool that translates assembly language into machine code, was developed by Nathaniel Rochester for the IBM 701 computer. This development marked a major step forward, enabling programmers to write more complex programs without delving into the intricac...
Assembler Translates text assembly language to binary machine code Input: a text file containing MIPS instructions in human readable form Output: an object file (.o file in Unix, .obj in Windows) containing MIPS instructions in executable form ...
