Optimizations​

This release bundles a few improved optimizations that improve code size and performance:

  • Improvements to object escape analysis and associated transformations (support for check-casts, returning parameters, true virtual and super invocations, comparing objects with null, and a whole new global cost function), resulting in fewer object allocations and more inlining.
  • Streamlined treatment of system annotations (a conceptual cleanup effort that lead to a size reduction).
  • Value numbering for branch conditions eliminating branches in code.

Build Speed / Reliability / Better Engineering​

  • Improved precision of analysis for class references from layouts and XML attributes, preventing Redex from removing referenced classes.
  • First steps towards addressing an ancient design bug in Redex causing improper handling of the package-private access modifier.
  • Performance improvements to Redex infrastructure.
