Assembly language, type of low-level computer programming language consisting mostly of symbolic equivalents of a particular computer's machine language. Computers produced by different manufacturers have different machine languages and require different assemblers and assembly languages.

In computer programming, assembly language (alternatively assembler language or symbolic machine code), 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 ...

Assembly language is converted into executable machine code by a utility program referred to as an assembler; the conversion process is referred to as assembly, or assembling the code. Assembly language uses a mnemonic to represent each low-level machine operation or opcode.

Assembly language is a low-level programming language for a computer, or other programmable device specific to a particular computer architecture in contrast to most high- level programming languages, which are generally portable across multiple systems.

An assembly language is a programming language that communicates with the hardware of a computer directly. An assembly language allows a software developer to code using words and expressions that can be easier to understand and interpret than the binary or hexadecimal data the computer stores and reads.

Labels A label can be placed at the beginning of a statement. ... A symbolic label consists of an identifier (or symbol) followed by a colon (:) (ASCII 0x3A). ... A numeric label consists of a single digit in the range zero (0) through nine (9) followed by a colon (:).

Labels are simply names for lines. You can have as many labels as you want. Typically, there are only a few places you'll want to refer to, for example the starting points of functions, loop starts and loop ends, and certain data storage locations. The assembler handles labels as aliases for numbers.

Recall that %rsp is the stack pointer and always points to the top of the stack. The register %rbp represents the base pointer (also known as the frame pointer) and points to the base of the current stack frame.
