Binary rewriting is changing the semantics of a program without having the source code at
hand. It is used for diverse purposes, such as emulation (eg, QEMU), optimization (eg …

Robust and powerful software instrumentation tools are essential for program analysis tasks
such as profiling, performance evaluation, and bug detection. To meet this need, we have …

Heterogeneous multiprocessors are increasingly important in the multi-core era due to their
potential for high performance and energy efficiency. In order for software to fully realize this …

This thesis addresses the challenges of building a software system for general-purpose
runtime code manipulation. Modern applications, with dynamically-loaded modules and …

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

Dynamic binary analysis (DBA) tools such as profilers and checkers help programmers
create better software. Dynamic binary instrumentation (DBI) frameworks make it easy to …

Modern data center applications exhibit deep software stacks, resulting in large instruction
footprints that frequently cause instruction cache misses degrading performance, cost, and …

Modern data center applications have rapidly expanding instruction footprints that lead to
frequent instruction cache misses, increasing cost and degrading data center performance …

This paper presents component techniques essential for converting executables to a high-
level intermediate representation (IR) of an existing compiler. The compiler IR is then …

Modern data center applications have deep software stacks, with instruction footprints that
are orders of magnitude larger than typical instruction cache (I-cache) sizes. To efficiently …
