15.21 Defining the Output Assembler Language

This section describes macros whose principal purpose is to describe how to write instructions in assembler language—rather than what the instructions do.

• File Framework: Structural information for the assembler file.
• Data Output: Output of constants (numbers, strings, addresses).
• Uninitialized Data: Output of uninitialized variables.
• Label Output: Output and generation of labels.
• Initialization: General principles of initialization and termination routines.
• Macros for Initialization Specific macros that control the handling of initialization and termination routines.
• Instruction Output: Output of actual instructions.
• Dispatch Tables: Output of jump tables.
• Exception Region Output: Output of exception region code.
• Alignment Output: Pseudo ops for alignment and skipping data.
