Accurate Compilation Replay via Remote JIT Compilation

When a JIT compiler crashes in a production deployment, compiler developers wish to reproduce the problem locally. However, existing approaches to replay compilation lack the necessary accuracy for this use case, or they introduce too much of a maintenance burden. We propose to achieve ac- curate compilation replay by running a remote compilation, recording the input to the remote compiler, and replaying the compilation using the recorded data. The benefit is greatly reduced iteration times for compiler developers when such an issue occurs.
