compilerbau-WS17-18

We're building a compiler. It'll compile things.

More specifically, this compiler will be able to translate a narrow subset of Java to JVM bytecode, taking a scenic tour through all the necessary steps in the form of multiple passes: lexing, parsing, typechecking, codegen'ing and serializing.

Setup

Install using

cabal build && cabal install

Maybe update cabal before using

cabal update && cabal install

Usage

Inside the dist/build/jc dir run ./jc File.java -l logFile

Run ./jc -h for additional information

Test Framework

Inside the project directory run

cabal repl test-core

and call main in order to see the tests running.

Alternatively run cabal test --show-details streaming

The Test-suite contains multiple testfiles:

test/
  - Correct/
    - BitWiseOperation
    - ClassAssign
    - ClassMethods
    - DoWhile
    - EmptyClass
    - EndlessForLoop
    - ForLoop
    - InstanceOf
    - InstanzVariable
    - LocalVariable
    - LogicOperations
    - LogicOperations2
    - MethodArguments
    - MethodCall
    - NewClass
    - OperatorOverloading
    - ShortIf
    - SimpleIf
    - SwitchCase
    - WhileLoop
    - WhileLoopCondition
  - Wrong/
    - Syntax/
      - Arithmetic
      - BraceError
      - ReturnTypeMissing
      - SemicolonMissing
      - TypeMissing
    - Type/
      - InstVarTypeMissmatch
      - MethodCall
      - MultipleReturnType
      - NoReturn
      - ReturnType
      - WrongArgumentType
      - WrongIfComparison

and additional example programs. All example programs are validated with normal java programs (print return from compiled example program).

  - Fibonacci
  - Fibonacci-Loop
  - FloorSquareRoot
  - GaußSum
  - Multiplication
  - Pow
