V-Pascal: an automatic vectorizing compiler for Pascal with no language extensions

A detailed anatomy of the automatic vectorizing compiler V-Pascal (Version 1, now operational) is given. With no language extensions, V-Pascal efficiently vectorizes the whole of arbitrarily given multiply nested for loops using the mechanism of vector indirect addressing. Higher functions of V-Pascal, such as vectorization of WHILE-DO and recursive calls, vectorization of relational operations on relational databases defined by record-type data structures, and automatic parallel decomposition for multiprocessor environments, are considered for Version 2, which is currently in the process of design and implementation
