Yacc sample grammars. Use ocamlyacc -v file.mly to generate file.output.
- e0.mly, e0.output : simple expressions, with shift-reduce conflicts
- e1.mly, e1.output: fix conflics with precedence directives
- e2.mly, e2.output: add unary "not" to grammar and get get new shift-reduce conflicts
- e3.mly, e3.output : fix conflics with precedence directives
- e4.mly, e4.output: add "e e" to grammar, get new conflicts
- e5.mly, e5.output: rewrite grammar to get rid of conflicts
- e6.mly, e6.output add unary "bang" to grammar and get a new shift-reduce conflicts
- e7.mly, e7.output : : fix conflics with precedence directives
Supervision Suggestions. Supervisors are strongly encouraged to assign practical work as well.
- (1) Lexing and parsing.
  - From Introduction to compiler design: Read Chapters 2 and 3 and do as many of the associated exercises as possible. Yes, solutions are available online, but don't peek before attempting on your own.
  - Some past tripos questions on similar topics:
    - y2015p3q3
    - y2012p3q4, (a), (b)
- (2) Program transformations.
  - Review basic transformations.

http://www.angelfire.com/tx4/cus/jasper/ : Jasper is a JVM bytecode disassembler, taking a binary foo.class file to an ASCII foo.j file in the Jasmin syntax. Note that the javap dissassembler also prodoces ASCII. However, there does not seem to be an associated assembler (please correct me if I'm wrong).
