Preface

The Oracle Solaris x86 Assembly Language Reference Manual documents the syntax of the Oracle Solaris x86 assembly language. This manual is provided to help experienced programmers understand the assembly language output of Oracle Solaris compilers. This manual is neither an introductory book about assembly language programming nor a reference manual for the x86 architecture.

Note - This Oracle Solaris release supports systems that use the SPARC and x86 families of processor architectures. The supported systems appear in the Oracle Solaris OS: Hardware Compatibility Lists. This document cites any implementation differences between the platform types.

In this document, these x86 related terms mean the following:

x86 refers to the larger family of 64-bit and 32-bit x86 compatible products.
x64 relates specifically to 64-bit x86 compatible CPUs.
"32-bit x86" points out specific 32-bit information about x86 based systems.

For supported systems, see the Oracle Solaris OS: Hardware Compatibility Lists.

Who Should Use This Book

This manual is intended for experienced x86 assembly language programmers who are familiar with the x86 architecture.

Before You Read This Book

You should have a thorough knowledge of assembly language programming in general and be familiar with the x86 architecture in specific. You should be familiar with the ELF object file format. This manual assumes that you have the following documentation available for reference:

Intel 64 and IA-32 Architectures Software Developer Manuals.
AMD64 Architecture Programmer's Manual (Advanced Micro Devices, 2003). Volume 1: Application Programming. Volume 2: System Programming. Volume 3: General-Purpose and System Instructions. Volume 4: 128-Bit Media Instructions. Volume 5: 64-Bit Media and x87 Floating-Point Instructions.
Oracle Solaris 11.1 Linkers and Libraries Guide
Oracle Solaris Studio 12.3: C User’s Guide
Man pages for the as(1), ld(1), and dis(1) utilities.

How This Book Is Organized

Chapter 1, Overview of the Oracle Solaris x86 Assembler provides an overview of the x86 functionality supported by the Oracle Solaris x86 assembler.

Chapter 2, Oracle Solaris x86 Assembly Language Syntax documents the syntax of the Solaris x86 assembly language.

Chapter 3, Instruction Set Mapping maps Oracle Solaris x86 assembly language instruction mnemonics to the native x86 instruction set.

Typographic Conventions

The following table describes the typographic conventions that are used in this book.

Table P-1 Typographic Conventions

Typeface	Description	Example
`AaBbCc123`	The names of commands, files, and directories, and onscreen computer output	Edit your `.login` file. Use `ls -a` to list all files. `machine_name% you have mail.`
`AaBbCc123`	What you type, contrasted with onscreen computer output	`machine_name%` `su` `Password:`
`aabbcc123`	Placeholder: replace with a real name or value	The command to remove a file is `rm` `filename`.
AaBbCc123	Book titles, new terms, and terms to be emphasized	Read Chapter 6 in the User's Guide. A cache is a copy that is stored locally. Do not save the file. Note: Some emphasized items appear bold online.

Shell Prompts in Command Examples

The following table shows UNIX system prompts and superuser prompts for shells that are included in the Oracle Solaris OS. In command examples, the shell prompt indicates whether the command should be executed by a regular user or a user with privileges.

Table P-2 Shell Prompts

Shell	Prompt
Bash shell, Korn shell, and Bourne shell	`$`
Bash shell, Korn shell, and Bourne shell for superuser	`#`
C shell	`machine_name%`
C shell for superuser	`machine_name#`
