This is an archived public release of MLton, version 20100608.

Changes since the last public release

  • New platforms.

  • Compiler.

    • Command-line switches.

      • Added: -mlb-path-var <name> <value>

      • Removed: -keep sml, -stop sml

    • Improved constant folding of floating-point operations.

    • Experimental: Support for compiling to a C library; see documentation.

    • Extended -show-def-use output to include types of variable definitions.

    • Deprecated features (to be removed in a future release)

      • Bytecode codegen: The bytecode codegen has not seen significant use and it is not well understood by any of the active developers.

      • Support for .cm files as input: The ML Basis system provides much better infrastructure for "programming in the very large" than the (very) limited support for CM. The cm2mlb tool (available in the source distribution) can be used to convert CM projects to MLB projects, preserving the CM scoping of module identifiers.

    • Bug fixes: see changelog

  • Runtime.

    • @MLton switches.

      • Added: may-page-heap {false|true}

    • may-page-heap: By default, MLton will not page the heap to disk when unable to grow the heap to accommodate an allocation. (Previously, this behavior was the default, with no means to disable, with security an least-surprise issues.)

    • Bug fixes: see changelog

  • Language.

    • Allow numeric characters in ML Basis path variables.

  • Libraries.

  • Tools.

    • mllex

      • Eliminated top-level type int = in output.

      • Added %posint command, to set the yypos type and allow the lexing of multi-gigabyte files.

    • mlnlffigen

      • Added command-line switches -linkage archive and -linkage shared.

      • Deprecated command-line switch -linkage static.

      • Added support for IA64 and HPPA targets.
