Compilers and Interpreters Assignment
Modify the recursive descent compiler for the language PL0 (provided on the course web page with this assignment) to add a skip statement, a multiple assignment statement, and an extended version of a loop statement.
Please ensure you follow the course Piazza bulletin board for any updates and further information on the assignment.
- You must only modify the files that must be submitted (see below).
- You must not modify any other files because we will be testing your implementation using the existing other files with your submitted files.
- Please do not reformat the files because we would like to just print the differences between the originals and the versions you hand in.
- Please keep the length of lines in your files below 100 characters, so that we can print them sensibly.
- Please avoid using non-standard characters, e.g. Chinese characters, including in the comments. Non- standard characters are not accepted by some Java compilers and all comments should be readable by the person assessing your assignment.
- Your implementation should be in Java 1.8. If you imported the A1 Eclipse project properly, it should already be set to 1.8, otherwise, set the Eclipse preferences for the Java compiler to 1.8 (or if not in Eclipse use the "-source 1.8" option to the Java compiler).
- Please remove any debugging output before your assignment is submitted because debugging output will cause your program to fail our automated testing of your assignment.
- Either avoid using tabs or set your tabs stops to 4 spaces (this is the default for Eclipse) so that your files will print sensibly.
Read the fine print in detail before you start! And, most important, when you have finished implementing the assignment, come back and reread the fine print again.
ASSIGNMENT INFORMATION -
Modify the recursive descent compiler for the language PL0 to add a skip statement, a multiple assignment statement, and a "do" statement. See the course web page for full details.
You need to submit the following list of files by separately attaching each file (NOT a zip or tar of the files). Note that the file names are case sensitive.
- Parser.java
- StaticChecker.java
- CodeGenerator.java
- StatementNode.java
- StatementVisitor.java
- StatementTransform.java
You can submit your assignment multiple times, but only the last copy submitted will be retained for marking.
- Please keep the length of lines in your files below 100 characters, so that we can print them sensibly.
- You should avoid using tabs or set your tabs stops to 4 spaces so that when we print them (with tab stops set to 4 spaces) they will print sensibly.
- Don't forget to remove any code generating debugging output before submission.
- Your implementation should be in Java 1.8.
- Remove any debugging output code.
- Remove any non-standard characters, e.g. Chinese characters.
