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.
The HLA v2.x language system is a command-line driven tool that consists of several components, including a shell program (e.g., hla.exe under Windows), the HLA language compiler (e.g., hlaparse.exe), a low-level translator (e.g., the HLABE, or HLA Back Engine), a linker (link.exe under Windows, ld under Linux), and other tools such as a ...
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. [5]
x86 assembly language includes instructions for a stack-based floating-point unit (FPU). The FPU was an optional separate coprocessor for the 8086 through the 80386, it was an on-chip option for the 80486 series, and it is a standard feature in every Intel x86 CPU since the 80486, starting with the Pentium.
Freely available software supporting the Hack computer includes a command line assembler application. The assembler reads Hack assembly language source tiles (*.asm) and produces Hack machine language output files (*.hack). The machine language file is also a text file.
They may be used for inline assembly inside the language, or even included as a library, but aren't always suitable for being used outside of their framework - no command-line tool exists, or only the intermediate representation can be used as their input, or the set of supported targets is very limited.
It is the successor to Program Assembler Loader , an earlier version of the PDP-11 assembly language without macro facilities. MACRO-11 was supported on all DEC PDP-11 operating systems. PDP-11 Unix systems also include an assembler (named as ), structurally similar to MACRO-11, but with different syntax and fewer features.
The line-oriented debugger DEBUG.EXE is an external command in operating systems such as DOS, OS/2 and Windows (only in 16-bit/32-bit versions [1]).. DEBUG can act as an assembler, disassembler, or hex dump program allowing users to interactively examine memory contents (in assembly language, hexadecimal or ASCII), make changes, and selectively execute COM, EXE and other file types.
