  • Compiler.
    • Added expert -pi-style {default|npi|pic|pie} and -native-pic {false|true} options, which can be used to override a target-determined default.
    • Fix a number of instances of excessive live data during compilation.
    • Disable Zone SSA optimization pass by default; the Zone pass is known to not be safe-for-space.
    • Statically allocate and initialize some global objects.
    • Many updates and improvements to C and LLVM codegens.
    • Add new BounceVars RSSA optimization pass to split the live ranges of RSSA variables.
    • Improve RssaShrink optimization.
    • Add support for alternate globalization strategies in ConstantPropagation.
    • Strengthen Useless optimization with respect to a number of primitives.
    • Add new DuplicateGlobals and SplitTypes SSA optimization passes.
    • Introduce new Overflow-checking primitives and remove old Overflow-checking primitives and special-case code required (e.g., Arith transfers in IRs) to support them.
    • Add parsers for XML, SXML, SSA, and SSA2 IRs.
  • Runtime.
    • Detect and report incompatible use of ASLR/PIE on load-world.
    • Added support for RISC-V architecture.
  • Language.
  • Libraries.
    • Basis Library.
      • Change OS.IO.poll to not be restarted when interrupted by a signal. (This is consistent with Socket.select.)
      • Add MLton.sizeAll: unit -> IntInf.int that returns the size of reachable live data.
      • Change type of MLton.size from 'a -> int to 'a -> IntInf.int, because with 64-bit systems, the size of a single object can exceed that representable by a signed 32-bit integer.
    • Other libraries.
      • Updated: ckit library, MLLPT library, MLRISC library, SML/NJ library
  • Tools.
  • Other.
    • Updates to simplify porting MLton.
    • Support parallel build (i.e., make -j). This mainly supports platforms/packagers that use a parallel make by default; it does not obtain significant build speedups.
    • Various updates to Makefiles. See Makefile.config for common and user-customizable configuration.
    • Characterize MLton-LICENSE as an instance of the Historical Permission Notice and Disclaimer (HPND) license, rather than BSD-style.
