Capturing Types

Martin Odersky, Aleksander Slawomir Boruch-Gruszecki, Ondrej Lhoták

Type systems usually characterize the shape of values but not their free variables. However, many desirable safety properties could be guaranteed if one knew the free variables captured by values. We describe CC

Safe Initialization of Objects

Martin Odersky, Fengyun Liu, Paolo Giosuè Giarrusso, Ondrej Lhoták

Every newly created object goes through several initialization states: starting from a state where all fields are uninitialized until all of them are assigned. Any operation on the object during its initialization process, which usually happens in the cons ...

Miniphases: Compilation using Modular and Efficient Tree Transformations

Martin Odersky, Dmytro Petrashko, Ondrej Lhoták

Production compilers commonly perform dozens of transformations on an intermediate representation. Running those transformations in separate passes harms performance. One approach to recover performance is to combine transformations by hand in order to red ...
