1.3 Unit Overview This unit is about software construction. Phases : writing a (cross-)compiler for a reasonably simple language. –Host : Jaguar. –Target : M68Ks in real-time lab. Programming language : C++. –In effect, ANSI C. Source language : C-- –A subset of ANSII C. Target language : M68K assembly.

1.4 Unit Overview II Phase 4 : writing a parser for a very simple language. –Host : Jaguar. –Target : None. Programming language : Anything you like. –Provided that it runs on Jaguar. Source language : SCL –The Simple Calculator Language. Target language : None.

1.5 Unit Structure Formally : –12 hours lectures. –12 hours directed practical. In practice : –About 8 hours lectures. –Unlimited (almost) surgery sessions. –Lots of individual work. –Lots more individual work.

1.6 Unit Assessment Phases : C-- –Three 5 minute software demonstrations. –Phase 1 : lexical analysis (10%) –Phase 2 : syntax analysis (20%) –Phase 3 : code generation (10%) Phase 4 : SCL –Code printout. –Copy of code on floppy. –60%

1.7 Unit Assessment II Marks awarded for –Functionality.  How much of C-- and SCL that your programs handle. –Good programming practice.  Comments, layout, variable names etc.  Declaring global variables will get you a 0.  Global constants are OK.

1.8 Textbooks Don’t really need a textbook. I’ll tell you everything that you need to know. If you’re really interested this is the classic text : Compilers : Principles, Techniques and Tools Aho A.V., Sethi R. & Ullman J.D. Addison-Wesley 1986 Personally, I wouldn’t touch it with a bargepole. This is the best book (IMHO) but it’s out of print : Understanding and Writing Compilers Bornat R. MacMillan 1979

1.9 Textbooks II If you’re going to get a book this one is suitable : Crafting A Compiler With C Fischer C.N. & LeBlanc R.J. Benjamin / Cummings Publishing Company 1991 This one might be interesting : Programming Language Processors In Java Watt D.A. & Brown R.F. Pearson Education 2000 This is just a good book : 1066 And All That Sellar W.C. & Yeatman R.J. Mandarin 1991
