- Arrays of value types can be created on the stack with `new`.
## V0.2
- Breaking change: return type of a function using `return-from #f` to return a value from the entire function is now the lowest common ancestor of all possible return values.
- Fixed bug where `return-from` could reach outside of an inlined function.
- Fixed bug where `return-from` might not behave correctly when returning from inside a let inside an inlined function.
- Added `fmin` and `fmax` floating point min and max. These work on multiple arguments and use the `minss`/`maxss` instructions for the best performance.
- Added `imul64` instruction for doing a real 64-bit multiplication. This must be used when porting code that looks at the `hi` register after an EE `mult`.
- Added `shl`, `shr`, and `sar` shifts which take a constant integer. These cannot be used with a variable shift amount.
- Added bitfield types to the type system
- Added the ability to cast integers to bitfield types
- Fixed a bug where functions with exactly 8 parameters created a compiler error.
## V0.4
- Breaking change: added new link kind to link table format. Code compiled with previous versions will still work, but code compiled in V0.4 that uses static pairs will cause a "unknown link table code 5" error.
- Added support for static pairs and lists. Symbols, integers, and strings are supported.
- Added much better support for setting fields of statics. Now you can set constants, symbols, strings, pairs, integers, floats, or other statics, including inlined structures/basics! Also uses the full type system for typechecking
- Fixed a bug where accessing an inline basic field did not apply the 4-byte basic offset.
- Made string/float constants go in the main segment when they are declared in the top-level segment, instead of the top-level segment. This is what GOAL seems to do (not 100% sure yet) and avoids issues where you set something to a string constant in the top-level. This avoids the possibility of memory bugs at the cost of more memory usage (likely very little additional memory).
- Added support for boxed arrays. They can be created with `new` and indexed with `->`. The compound type `(array <elt-type>)` is used to describe an array with a given content type.
- Breaking change: the register class `xmm` for a single float was renamed to `fpr` to distinguish it from other uses of `xmm` registers.
- Breaking change: the message format for reset and shutdown messages sent between the listener and runtime has changed.
- Improved code-generation quality where accessing a field or similar with an offset of zero from a base register.
- The listener now uses message IDs to more robustly handle the situation where a response messages comes, but is extremely late, or if some sent messages are skipped.
- Fixed bug where references to the debug segment using RIP-relative links were not set to zero by the linker when the debug segment isn't loaded.
- The `rlet` form now supports 128-bit vector float registers with the `vf` register class.
- Added support for "vector float" assembly operations, including `lvf`, `svf`, `xor`, `sub`, `add`, and `blend`.
