ICSE 2024
Fri 12 - Sun 21 April 2024 Lisbon, Portugal
Wed 17 Apr 2024 15:00 - 15:07 at Amália Rodrigues - Evolution 1 Chair(s): Jonathan Sillito

We present JOG, a framework for developing peephole optimizations and accompanying tests for Java compilers. JOG allows developers to write a peephole optimization as a pattern in Java itself. Such a pattern contains code before and after the desired transformation defined by the peephole optimization, with any necessary preconditions, and the pattern can be written in the same way that tests for the optimization are already written in OpenJDK. JOG automatically translates each pattern into C/C++ code as a JIT optimization pass, and generates tests for the optimization. Also, JOG automatically analyzes the shadow relation between a pair of optimizations where the effect of the shadowed optimization is overridden by the other. We used JOG to write 162 patterns, including many patterns found in OpenJDK and LLVM, as well as some that we proposed. We opened ten pull requests (PRs) for OpenJDK, on introducing new optimizations, removing shadowed optimizations, and adding generated tests for optimizations; nine of PRs have already been integrated into the master branch of OpenJDK. The demo video for JOG can be found at https://youtu.be/z2q6dhOiqgw.
