What's new

• WIP Dalvik AST model
  • Not intended for use just yet as things are not fully fleshed out, but if you're curious it is there
• Changes Compiler result from ClassRepresentation to ClassResult which will hold analysis data even if a full ClassRepresentation could not be built
  • This allows getting partial analysis data even if there were build problems
  • Before, analysis data required the class be fully buildable in order to access
• AST to CodeElement and CodeElement to AST lookups in AnalysisResults
  • Pairs will with the prior change above with partial builds
  • Allows easy look-ups of compilation mappings without having to do a lot of work yourself
• Shortcuts for common invokedynamic bootstrap methods
  • LambdaMetaFactory.metafactory -> java.lang.invoke.LambdaMetafactory.metafactory(MethodHandles.Lookup, String, MethodType, MethodType, MethodHandle, MethodType)
  • LambdaMetaFactory.altMetafactory -> java.lang.invoke.LambdaMetafactory.altMetafactory(MethodHandles.Lookup, String, MethodType, Object...)
  • ConstantBootstraps.nullConstant -> java.lang.invoke.ConstantBootstraps.nullConstant(MethodHandles.Lookup, String, Class)
  • ConstantBootstraps.primitiveClass -> java.lang.invoke.ConstantBootstraps.primitiveClass(MethodHandles.Lookup, String, Class)
  • ConstantBootstraps.enumConstant -> java.lang.invoke.ConstantBootstraps.enumConstant(MethodHandles.Lookup, String, Class)
  • ConstantBootstraps.getStaticFinal -> java.lang.invoke.ConstantBootstraps.getStaticFinal(MethodHandles.Lookup, String, Class, Class)
  • ConstantBootstraps.invoke -> java.lang.invoke.ConstantBootstraps.invoke(MethodHandles.Lookup, String, Class, MethodHandle, Object...)
  • ConstantBootstraps.fieldVarHandle -> java.lang.invoke.ConstantBootstraps.fieldVarHandle(MethodHandles.Lookup, String, Class, Class, Class)
  • ConstantBootstraps.staticFieldVarHandle -> java.lang.invoke.ConstantBootstraps.staticFieldVarHandle(MethodHandles.Lookup, String, Class, Class, Class)
  • ConstantBootstraps.arrayVarHandle -> java.lang.invoke.ConstantBootstraps.arrayVarHandle(MethodHandles.Lookup, String, Class, Class)
  • ConstantBootstraps.explicitCast -> java.lang.invoke.ConstantBootstraps.explicitCast(MethodHandles.Lookup, String, Class, Object)
  • SwitchBootstraps.enumSwitch -> java.lang.runtime.SwitchBootstraps.enumSwitch(MethodHandles.Lookup, String, MethodType, Object...)
  • SwitchBootstraps.stringSwitch -> java.lang.runtime.SwitchBootstraps.typeSwitch(MethodHandles.Lookup, String, MethodType, Object...)
  • ObjectMethods.bootstrap -> java.lang.runtime.ObjectMethods.bootstrap(MethodHandles.Lookup, String, TypeDescriptor, Class, String, MethodHandle...)
• Field and method descriptors are now verified for correct formatting
• More supported values in the provided BasicMethodValueLookup (which got moved to a new package)
• Value lookups for fields/methods are only attempted when value content is known

What's Fixed

• Tokenizer associating tokens with wrong column
• OOBE when printing a virtual method with no parameters
• Unintended breakage of annotation path selection in CompilerOptions
• ASTElement.range() yielding unexpected positions due to unsorted children
• Missing special case handling for numbers (NaN and the like)
• Incorrectly creating additional parameters when disassembling methods with wide-type parameters
• Many analysis engine problems
  • nop, arraylength, *aload and *astore instructions not being implemented
  • anewarray not popping array size off the stack
  • checkcase not changing the value type on the stack
  • Value analysis truncating small floats and doubles
  • Analysis engine errors not being reported in the common error collector system
  • Revisiting control flow would not merge frames, but overwrite them with the last visited iteration
  • Jump target frames being put at the wrong index
  • Unmatched push and pop in a variety of stack-manipulating and math instructions
  • Incorrect handling of frame merging for terminal instructions
  • Incorrect printing of annotation enum values
  • Incorrect printing of annotation class values
  • Unexpected re-ordering of annotation values
  • Missing char/special-case-number support for annotation values
