Introduction

This compiler compiles the language to the JVM.

Testing

Easy way:

$ ./run.sh /tests/add.c

This will compile, assemble, link and run the program The jasmin and class files will be moved to testout folder Inspect the output by accessing testout/add.j for example

You can run all the tests by: $ for file in tests/* ; do ./run.sh $file ; done"

Hard(er) way:

  1. Compile a .c file to the jvm language using sbt $ sbt "run tests/add.c"

This will generate the file add.j in the current directory

  1. Use the jasmine assembler to generate class file $ java -jar jasmin.jar add.j

  2. Compile the standard library (written in java, containing printd etc) $ javac Lib.java

  3. Execute program $ java add

Notes

  • The typechecking and compilation happen in two seperate sweeps.
  • Compilation will not proceed if there are type errors
  • Typechecker is very rigorous
  • string + string is allowed, but int + string is not. Any other operations on strings also prohibited.
  • There is no preprocessor
  • Many of the tests have been modified to remove #define's and #include's
  • Strings are not mutable. I have modified erato.c to use tab = put_char_at(tab, j, '0')
  • You can add new functions to the standard library by modifying Lib.java, but functions should be declared in the c file before usage.
