Features
|
|
|
|
- Improved garbage collector performance for large heaps.
|
|
- Generate faster compiled code for:
|
|
- `car`, `cdr`, and most built-in predicates.
|
|
- Calls to `list` that contain less than five arguments.
|
|
- Calls to `map` and `for-each` that only pass a single list.
|
|
- Allow optimization of some simple self-recursive functions.
|
|
- Allow the optimizer to beta expand a wider range of function calls.
|
|
|
|
Bug Fixes
|
|
|
|
- Fixed a bug where `current-jiffy` was returning total clock time of the process. Such an approach cannot be used to measure time accurately when more than one thread is executing concurrently.
|
|
- Prevent the possibility of an infinite loop by not beta expanding recursive function calls.
