Kotlin compiler fuzzer and reduktor

Requirements:

• NodeJS
  • npm install kotlin
  • npm install kotlin-test

Usage:

• Compile
  • ./compile.sh
• Start
  • gradlew runBBF - to start fuzzing

All options (backends, dir for results, etc.) specifies in bbf.conf file

Instrumentation notes

• The class com.stepanov.bbf.coverage.CompilerInstrumentation is duplicated in both the Java agent module and in the main project. Their contents should be kept identical.
• -javaagent:<path-to-instrumenter-jar> VM option should be present in order for the compiler to be instrumented.
• A new instrumenter jar can be assembled with the kotlinc-instrumenter/jar Gradle task. The new jar's default new position is the main project's src/main/resources.
