DEC OSF/1 Assembly Language Programmer's Guide

This manual provides a comprehensive guide for experienced assembly language programmers working with the DEC OSF/1 Alpha AXP compiler system. It details the architecture-based considerations (registers, bit and byte ordering, addressing, and exceptions), lexical conventions, instruction sets (main and floating-point), assembler directives, and programming considerations such as calling conventions, program models, and memory allocation. It also includes sections on object file formats (OMAGIC, NMAGIC, ZMAGIC), symbol tables, and program loading and dynamic linking. Appendices provide quick-reference instruction summaries and descriptions of Privileged Architecture Library (PALcode) instructions.
