Software systems have been using" just-in-time" compilation (JIT) techniques since the
1960s. Broadly, JIT compilation includes any translation performed dynamically, after a …

Virtual machines face significant performance challenges beyond those confronted by
traditional static optimizers. First, portable program representations and dynamic language …

Optimizing compilers for object-oriented languages apply static class analysis and other
techniques to try to deduce precise information about the possible classes of the receivers of …

This paper reports on the design, implementation, and empirical results of a new method for
dealing with the aliasing problem in C. The method is based on approximating the points-to …

Polymorphic inline caches (PICs) provide a new way to reduce the overhead of polymorphic
message sends by extending inline caches to include more than one cached lookup result …

Interprocedural analyses enable optimizing compilers to more precisely model the effects of
non-inlined procedure calls, potentially resulting in substantial increases in application …

Jalapeño is a virtual machine for Java™ servers written in the Java language. To be able to
address the requirements of servers (performance and scalability in particular), Jalapeño …

SELF's debugging system provides complete source-level debugging (expected behavior)
with globally optimized code. It shields the debugger from optimizations performed by the …

A large number of call graph construction algorithms for object-oriented and functional
languages have been proposed, each embodying different tradeoffs between analysis cost …

Abstrach Object-oriented programs are difficult to optimize because they execute many
dynamically-dispatched calls. These calls cannot easily be eliminated because the compiler …
