Tru64 UNIX Object File and Symbol Table Format Specification

This document is the official technical specification for the Tru64 UNIX eCOFF object file and symbol table formats (V3.13), outlining their legal uses and interpretations for developers. It details the structure and usage of object files and archives, covering main components such as file headers (e.g., a.out, section headers), executable instructions and data segments, relocation information (normal, compact, linkerdef, dynamic), and the symbol table (containing linking and debugging data, including language-specific features). The manual also describes dynamic loading mechanisms and the comment section. It's intended for compiler, debugger, and other tool developers who create or manipulate these files on Alpha-based Tru64 UNIX systems (V5.1 and greater for many features).
