We describe LLVM (low level virtual machine), a compiler framework designed to support
transparent, lifelong program analysis and transformation for arbitrary programs, by …

A great deal of software is distributed in the form of executable code. The ability to reverse
engineer such executables can create opportunities for theft of intellectual property via …

Modern programming languages and software engineering principles are causing
increasing problems for compiler systems. Traditional approaches, which use a simple …

Performance optimization for large-scale applications has recently become more important
as computation continues to move towards data centers. Data-center applications are …

Machine code disassembly routines form a fundamental component of software systems that
statically analyze or modify executable programs, eg, reverse engineering systems, static …

Reverse engineering of software is the process of recovering higher-level structure and
meaning from a lower-level program representation. It can be used for legitimate purposes …

While profile guided optimizations (PGO) and link time optimiza-tions (LTO) have been
widely adopted, post link optimizations (PLO) have languished until recently when …

This paper describes PLTO, a link-time instrumentation and optimization tool we have
developed for the Intel IA-32 architecture. A number of characteristics of this architecture …

A major challenge of applying profile-based optimization on large real-world applications is
how to capture adequate profile information. A large program, especially a GUI-based …

Many opportunities exist to improve micro-architectural performance due to performance
events that are difficult to optimize at static compile time. Cache misses and branch mis …
