Whiley v0.3.12 Released!

Well, crikey, what a long time since the last release.  Things haven’t changed a whole lot, apart from various bug fixes.  Probably the most interesting update is the inclusion of reference counting of compound structures to enable in-place updates and prevent unnecessary cloning.  This leads to some nice performance improvements.  Quite a bit of work has been done on the benchmarks as well, and also the eclipse plugin.


  • Added support for proper reference counting of compound structures.  This employs a live variables analysis to determine when a local variable is dead.

  • Reworked the name resolution and module loading system.  This was done primarily to support build tools such as ant and eclipse.

  • Improved the Ant task.

  • Further improved the runtime checking of constraints.

  • Added some rudimentary reporting of memory usage by the various compiler stages.
