  25 JavaSoft HotSpot Architecture Description Language Syntax Specification
  26 
  27 Version 0.4 - September 19, 1997
  28 
  29 A. Introduction
  30 
  31 This document specifies the syntax and associated semantics for the JavaSoft
  32 HotSpot Architecture Description Language.  This language is used to describe
  33 the architecture of a processor, and is the input to the ADL Compiler.  The
  34 ADL Compiler compiles an ADL file into code which is incorporated into the
  35 Optimizing Just In Time Compiler (OJIT) to generate efficient and correct code
  36 for the target architecture.  The ADL describes three bassic different types
  37 of architectural features.  It describes the instruction set (and associated
  38 operands) of the target architecture.  It describes the register set of the
  39 target architecture along with relevant information for the register allocator.
  40 Finally, it describes the architecture's pipeline for scheduling purposes.
  41 The ADL is used to create an architecture description file for a target
  42 architecture.  The architecture description file along with some additional
  43 target specific oracles, written in C++, represent the principal effort in
  44 porting the OJIT to a new target architecture.
