Release Notes


Version 110.99.1
April 12, 2021


Summary

This i a patch release that includes a few bug fixes and which enables running SML/NJ on M1 (aka Arm) Macs under Rosetta2. Because the system is running under emulation, it may not be as reliable as when running as a native application on a AMD64 processor. We are working on a native Arm64 port that we hope to release this summer.

Details

Runtime System

Modified the stack frame layout on AMD64 to better support the LLVM backend (currently under development).

SML/NJ Library

The ListMergeSort.sort function is now stable (as claimed by the documantation).

Added some additional mechanism to the JSONUtil structure to make writing robust queries easier.

Installation

It is possible to install the amd64 version of the system on M1 Macs. Because these machines run Big Sur, you will need to control-click on the installer package and open it with the installer application.

32-bit macOS issues

While the x86 installer for 110.99.1 works on macOs 10.14 Mojave, building from source requires some extra steps because the version of Xcode distributed for Mojave does not include a 32-bit SDK.

Another issue that you may encounter when building on macOs 10.14 Mojave is an error message for a shell script of the form

  /bin/sh: bad interpreter: Operation not permitted

This error arises because the com.apple.quarantine attribute is set on the shell script. To fix the problem, remove the attribute using the command

  xattr -d com.apple.quarantine shell-script

and resume the build.

Bugs

Here is a list of tracked bugs fixed (or closed) with this release, please see the bug tracker for more details.

ListMergeSort is documented as stable, but is not (esp. since 110.78 rewrite!)
