|
|
|
|
|
* ===================================================================
|
|
|
|
|
* This file is a modified version of one originally found in the
|
|
|
|
|
* VTransformer Examples directory of JavaCC1_1. It has been
|
|
|
|
|
* modified to accept Java source code for Java 1.2. Basically,
|
|
|
|
|
* this means a new key word was added, 'strictfp', and that keyword
|
|
|
|
|
* added to the appropriate productions and LOOKAHEADs (where other,
|
|
|
|
|
* similar keywords are listed as possible choices). This involved
|
|
|
|
|
* changing 11 lines.
|
|
|
|
|
*
|
|
|
|
|
* Some other minor changes were made, which can be found by doing
|
|
|
|
|
* a search on 'DW, 7/99'.
|
|
|
|
|
*
|
|
|
|
|
* The goal of this effort was for the grammar to be able to parse
|
|
|
|
|
* any legal Java 1.2 source code. It does not reject all illegal
|
|
|
|
|
* cases, but neither did the original. Plus, when it comes to
|
|
|
|
|
* the new 'strictfp' keyword, the Java Compiler from Sun (JDK1.2.1)
|
|
|
|
|
* also does not reject all illegal cases, as defined by the
|
|
|
|
|
* "Updates" document found at
|
|
|
|
|
* http://java.sun.com/docs/books/jls/strictfp-changes.pdf
|
|
|
|
|
* (see the testcases.txt file for details).
