llvm-cov

Overview

llvm-cov is a command-line utility shipped with LLVM that converts raw profile data produced by LLVM's instrumentation-based coverage passes into human-readable coverage reports (text, HTML, and JSON formats). It works in conjunction with the instrumentation emitted by compilers such as clang and rustc when source-based code coverage is enabled.
