New Language Features

Compiler Improvements

Compile Time Speed Optimizations

• Multithreaded frontend by default
  • Using the new and improved work stealing thread pool system
  • Fix numerous race conditions
  • Replace many instances of MPMC queues with MPSC queues
  • Replace many instances of BlockingMutex with RwMutex
  • Replace many instances of RecursiveMutex with BlockingMutex
• Multithread backend when the experimental -use-separate-modules is used
  • -use-separate-modules turns each package into a separate translation unit (object file) and then links them all together. This allows LLVM be multithreaded at the translation unit stage (LLVM Module).
  • -use-separate-modules will not produce as good code compared to without it because of the multiple translation units.
• Improvements to the hash table related structures (StringMap, StringSet, PtrMap, PtrSet)
• Big improvement to compile times due to the above improvements

General fixes

• Improved type inference for ternary if expressions
• Remove auto_cast from procedure parameters
• Fix bug with built-in matrix transpose caused by misalignment of the value
• Fix valgrind assembly generation
• Allow when statements within foreign blocks at the file scope

New Packages

Package Improvements
