Presentation Transcript

  1. Epsilon Compiler Advanced Compilers Progress Report James Simister 11/3/99

  2. Focus • Develop Epsilon language • Extend Sheba compiler to Epsilon language • Implement aspect weaving in compiler • Add optimizations • Develop test cases • OO calculator • Debugging aspect

  3. Language Development • I’ve hammered out the grammar for the Epsilon language • Sheba was extended to: • support objects and inheritance • no nested objects • support aspects • advice for before, after, and replace • wildcard matching for class & method names

  4. Compiler Modification • Original compiler was one-pass, no explicit parse tree, no optimization • Must be extended: • lex & yacc input to accept Epsilon grammar & syntax • IR parse tree • Source-to-source transform for aspect weaving • Lower-level IR for optimizations? • Add passes for optimization
