Added

  • New fusion engine by Amar Topalovic and Walter Restelli-Nielsen.
    Fuses more, which is good for some programs and bad for others.
    Most programs see no change. This is mainly a robust foundation for
    further improvements.

  • New experimental backend: ispc. By Louis Marott Normann,
    Kristoffer August Kortbæk, William Pema Norbu Holmes Malling, and
    Oliver Bak Kjersgaard Petersen.

  • New prelude functions: hist, spread. These function as
    non-consuming variants of reduce_by_index and scatter.

  • Using == to compare arrays is now deprecated.

  • New command: futhark tokens. You probably don't care about this one.

  • In the C API, opaque types that correspond to tuples or records can
    now have their elements inspected and be created from elements
    (#1568).

  • New server protocol commands: types, fields, entry_points.

  • Tuples and records can now be passed from FutharkScript to Futhark
    entry points (#1684).

Fixed

  • Sometimes missing cases in match expressions were not detected.

  • A defective simplification rule could in very rare cases lead to
    infinite recursion in the compiler (#1685).

  • Some broken links in futhark doc output (#1686).

  • Incorrect checking of whether a function parameter is consumable
    based on its type (#1687).

  • Missing aliases for functions that return multiple aliased values
    (#1690).

  • new/values functions for GPU backends are now properly
    asynchronous (#1664). This may uncover bugs in application code.
