实现Ada的中间语言—Diana语言库的方法

A METHOD FOR THE IMPLEMENTATION OF DIANA—THE INTERMEDIATE LANGUAGE OF ADA

DIANA是ADA程序的一种中间表示形式,它适用于ADA编译程序中两个主要工具—前端和后端之间的通信,也是ADA环境中各种工具之间的公共数据界面。DIANA的不同应用场合,可以以不同的方法来实现它。在这篇文章中,介绍了一种实现DIANA语言的简单方法,其中包括了DIANA的特性、实现的思想及操作。这种方法的特点是简单,而且易于实现。

The Diana is an internal representation of Ada source program. It is not only used to communicate in the front end and back end of the Ada compiler, but also the common data interface in the various tools of the Ada environment. It can be implemented in different ways while in different applications. This article describes a method for the implementation of Diana which includes the features of it, the implementation idea and the related operation.
