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

Modern Java programs, such as middleware and application servers, include many complex
software components. Improving the performance of these Java applications requires a …

CodeSurfer/x86 is a prototype system for analyzing x86 executables. It uses a static-analysis
algorithm called value-set analysis (VSA) to recover intermediate representations that are …

Calling context enhances program understanding and dynamic analyses by providing a rich
representation of program location. Compared to imperative programs, object-oriented …

Calling context profiles are used in many inter-procedural code optimizations and in overall
program understanding. Unfortunately, the collection of profile information is highly intrusive …

Inlining is a core transformation in optimizing compilers. It replaces a function call (call site)
with the body of the called function (callee). It helps reduce function call overhead and …

Coverage-guided fuzzers expose bugs by progressively mutating testcases to drive
execution to new program locations. Code coverage is currently the most effective and …

Method inlining is considered to be one of the most important optimizations in a compiler.
However, a poor inlining heuristic can lead to significant degradation of a program's running …

A tracing controller may utilize a binary execution trace mechanism to trace execution of
compiled application machine code. The tracing controller may initiate hardware tracing to …

Inlining improves the performance of programs by reducing the overhead of method
invocation and increasing the opportunities for compiler optimization. Incorrect inlining …
