13.19 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.
