资源说明：This preface is a brief description of the SunOS
TM
assembler that runs on x86. This
preface also includes a list of documents that can be used for reference.
The SunOS assembler that runs on x86, referred to as the “SunOS x86” in this
manual, translates source files that are in assembly language format into object files
in linking format.
In the program development process, the assembler is a tool to use in producing
program modules intended to exploit features of the Intel
®
architecture in ways that
cannot be easily done using high level languages and their compilers.
Whether assembly language is chosen for the development of program modules
depends on the extent to which and the ease with which the language allows the
programmer to control the architectural features of the processor.
The assembly language described in this manual offers full direct access to the x86
instruction set. The assembler may also be used in connection with SunOS 5.1 macro
preprocessors to achieve full macro-assembler capability. Furthermore, the assembler
responds to directives that allow the programmer direct control over the contents of
the relocatable object file.
This document describes the language in which the source files must be written. The
nature of the machine mnemonics governs the way in which the program’s
executable portion is written. This document includes descriptions of the pseudo
operations that allow control over the object file. This facilitates the development of
programs that are easy to understand and maintain.
