Modern software engineering techniques introduce an overhead to programs in terms of performance and code size. A traditional development environment, where only the compiler optimizes the code, cannot completely eliminate this overhead. To effectively remove the overhead, tools are needed that have a whole-program overview. Link-time binary rewriting is an effective technique for whole-program optimization and instrumentation.

Diablo is a novel framework to reliably perform link-time program transformations. This framework is designed to be retargetable, supporting multiple architectures and development toolchains.

While Diablo's initial focus has been mostly on program compaction, binary rewriting has a much broader range of applications: speed optimizations, power consumption optimizations, size optimizations, program obfuscation and watermarking, instrumentation, etc.
