Release Notes

Version 110.89
June 1, 2019

Summary

This release continues the march toward 64-bit support. The main change is that the bindings of the `FixedInt`, `LargeWord`, and `Position` structure aliases are now 64-bit. This change will break code that assumes that these structures are the same as `Int32`, `Word32`, and `Int32` (respectively).

This version may be unstable, so we recommend sticking with Version 110.87 for production work. Also, we have not finished porting changes to the Windows version of the runtime system, so we are not releasing a Windows MSI file for this version.

Details

Installation

While the installer for 110.89 works on macOS 10.14 Mojave, building from source requires some extra steps.

Compiler

• Fixed some bugs in the implementation of the `Word64` arithmetic operations.

• Simplified the code generator by removing disabled optimization features (memory disambiguation and GC types).

• Added missing contractions for `QUOT` and `REM` primops.

Basis Library

• The `FixedInt`, `LargeWord`, and `Position` structures are now all 64-bit. Thus the `Int64` and `Word64` structures properly conform to the Basis Specification.
Another effect of this change is that files that are over $2^{30} - 1$ bytes in size are now supported (bugs 33 and 36).

MLRISC and NLFFI

• Fixed code that assumed that `LargeWord` and `Word32` are the same.

Runtime System

• The runtime system was written assuming ANSI X3.159-1989 Standard C; in this releaser, we have added the use of inline functions, which where added in ISO C99. While Microsoft’s Visual Studio does not fully support the standard, it is generally compatible with the ISO C99.

• Allocation of small objects was previously implemented using macros; we now use inline functions. Inline functions are more robust and type safe, and also enable cleaner handling of 32-bit integers, which are boxed on 32-bit targets, but unboxed on 64-bit targets.

• Removed makefiles and code for arichtectures and operating systems that are no longer supported.
