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
andREM
primops.
Basis Library
-
The
FixedInt
,LargeWord
, andPosition
structures are now all 64-bit. Thus theInt64
andWord64
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
andWord32
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.

A note about 64-bit support
Apple is in the process of deprecating 32-bit support in macOS. With macOS 10.14 Mojave, compiling 32-bit applications, such as the SML/NJ runtime system, requires using an older SDK. The SML/NJ installer, however, works without issue on macOS 10.14 Mojave.
We have been working on 64-bit support since 110.82 we expect to have it in place before the release of macOS 10.15.
