Mostly complete pure rust implementation of parsing llvm instrumentation profile data

llvm-profparser

This is a reasonably complete to parse the llvm instrumentation profraw file format and avoid the need to install and use the llvm-profdata/llvm-cov binaries. It aims to be backwards compatible with as many llvm versions that could be used for coverage data in Rust projects and currently supports the following llvm versions: 11, 12, 13, 14, 15.

This project is not affilated with the llvm-project in anyway! It is merely a parser for some of their file formats to aid interoperability in Rust.

Contributing

All of the functionality required has been implemented, however there are areas to improve in handling unexpected or invalid files. To start fining issues there's a fuzz directory which will undoubtedly reveal some issues that can be fixed. Go into the fuzz directory for guides on how to run.
