Intrinsically typed compilation with nameless labels

Typed Compilation Against Non-manifest Base Classes

Much recent work on proof-carrying code aims to build certifying compilers for single-inheritance object-oriented languages, such as Java or C#. Some advanced object-oriented languages support compiling a derived class without complete information about its base class. This strategy—though necessary for supporting features such as mixins, traits, and first-class classes—is not wellsupported by ...

Typed Compilation of Re ursive Datatypes

The Nameless

A personal survey of the abortion problem in Britain, based on articles in The Observer. Paul Ferris sets out the present situation clearly for the layman and gives case-histories which are often moving. He makes it clear that the existing law is archaic and socially unjust. Abortion is very much a mental health problem and psychiatrists have recently been used as a scapegoat, because society w...

A Typed Intermediate Language for Flow-Directed Compilation

We present a typed intermediate language λ for optimizing compilers for function-oriented and polymorphically typed programming languages (e.g., ML). The language λ is a typed lambda calculus with product, sum, intersection, and union types as well as function types annotated with flow labels. A novel formulation of intersection and union types supports encoding flow information in the typed pr...

A Compilation Model for Aspect-Oriented Polymorphically Typed Functional Languages

Introducing aspect orientation to a polymorphically typed functional language strengthens the importance of type-scoped advices; i.e., advices with their effects harnessed by type constraints. As types are typically treated as compile time entities, it is highly desirable to be able to perform static weaving to determine at compile time the chaining of type-scoped advices to their associated jo...
