      o Add the new function order-layout-inherits to correctly order the · 9793164a
      dtc authored
        layouts within the layout-inherits vector. This ensures that
        the compiler can generate inline type tests for hierarchical classes.
      
      o Modify the definition of the stream class to be hierarchical.
      
      o Have the condition classes correctly order their layout-inherits
        so that the hierarchical condition class is placed at it specified depth.
      
      o Enhance the compiler instance typep transform to generate inline
        type tests for hierarchical classes, not just for structures.

      Just grab the lisp class direct-superclasses for the pcl · ad770090

      structure-class direct superclasses. This handles both normal
      structures with a single superclass, and other structure like classes
      such as conditions and streams which may have multiple superclasses.

      These changes remove some obsolete and unused type system interface codes, · 94577d17

      and introduces code to "inform-type-system-about-std-class". The effect
      of this new code is to put minimal class definitions into the compile-time
      environment to prevent undefined-type warnings. These definitions are
      replaced with the correct class defs at load-time.

      Fix the handling of :unread and :clear-input in the stream · 40f31f66
      dtc authored
      misc functions synonym-misc, two-way-misc, and concatenated-misc.
      These streams encapsulate other input streams which may have an input
      buffer so they need to call unread-char and clear-input on the
      encapsulated stream rather than directly calling the encapsulated
      streams misc method as the misc methods are below the layer of the
      input buffer.

      o Fix the generation of new variable leafs by the proclaim functions. · b8bbec47
      dtc authored
        The new variables were being created by copying the old leafs which
        incorrectly copied over any refs, or sets etc, which should have been
        cleared in the new leafs.
      
      o Fix the handling of the 'special identifier in the proclaim IR1
        translator which had been incorrectly using the identifier rather than
        the variable name when updating the hash tables.

      Reworking of the values-type system to overcome a number of inconsistencies · daf333f4
      dtc authored
      causing problems:
      
      o Redefine coerce-to-values to convert a single value type into (values type),
        rather than the former definition (values type &rest t). A single value
        type such as fixnum is now equivalent to (values fixnum). Values-type-union
        and values-type-intersection will canonicalise values types with a
        single value such as (values fixnum) back to a single value type
        such as fixnum.
      
      o Now when the compiler makes assertions for the first value of
        continuations that may be generating multiple values it asserts the
        type as (values type &rest t), or as (value &optional type &rest t) if
        it is not sure that the continuation does generate a value.
      
      o Enhance the type check generation to better handle the now common
        values types with optional and rest arguments. Add the new function
        Values-types-asserted which converts asserted optional and rest
        arguments to required arguments that have been proven to be delivered,
        Thus an assertion such as (values &optional fixnum &rest t) will
        generate a fixnum type check if the proven type if (values t).
      
      o The compiler is now far more likely to pickup attempts to use an
        assertion to select a subset of values. For example
        (the (values fixnum) (values x y)) will generated a compiler warning.
      
      o Update single values type assertions where appropriate to clarify that
        the received values may be optional or that multiple values may be
        received. For example, a macro argument which had been asserted to be
        a list via (the list ,...) would now be asserted to be
        (the (values &optional list &rest t)) etc.
      
      o Have the IR1 translator for THE convert single value types into
        (values &optional type &rest t) so that code such as
        (the fixnum (values x y)) will still work acceptably. This does not
        restrict the possible type assertions as the values types may be used
        and are not modified.
