GNU-Syntax Arm Assembly Language Reference Guide

This part of the tiarmclang user guide provides information about GNU-syntax Arm assembly language that is recognized and processed by the tiarmclang integrated GNU-syntax Arm assembler.

• Command Line: For an overview of assembler command-line options, see GNU-Syntax Arm Assembler Command Line.

• Assembly Syntax: For an overview of GNU Arm assembly syntax, see GNU-Syntax Arm Assembly Source Anatomy.

• Instructions: For links to documentation of assembly instructions for your Arm device, see GNU-Syntax Arm Assembly Instructions.

• Directives: For documentation of the assembly directives supported with tiarmclang, see GNU-Syntax Arm Assembly Directives.

Additional documentation for using assembly with tiarmclang is provided elsewhere:

• For information about migrating legacy TI-syntax Arm assembly language instructions and directives to GNU-syntax Arm assembly, see Migrating Assembly Language Source Code.

• For information about the tiarmclang command line and about the tiarmasm standalone TI-syntax assembler, see About the tiarmclang Arm Assemblers.

• For information about the Application Binary Interface (ABI) for the Arm architecture, see the ABI specifications page and the Addenda.

• Information about GNU-syntax Arm assembly language is available in GNU and Arm documentation online. The majority of the documented syntax is recognized and processed by tiarmclang’s integrated GNU-syntax Arm assembler. Here are some suggested sources:

  • Arm Developer’s Instruction Set Architecture

  • GNU Assembler - Using as

  • GNU Assembler (as) - ARM Dependent Features
