| # LLVM `profdata` format support library |
| |
| This library provides support for the `llvm-profdata` file format in a program |
| compiled using Clang's SourceBasedCoverage or LLVM profiling instrumentation. |
| This is a substitute for the standard runtime included in the `compiler-rt` |
| suite. It's meant for low-level environments like kernels and boot loaders |
| where toolchain-supplied runtime libraries are not available. It does not |
| implement any I/O or data transport itself, but only a simple API for getting a |
| dump in `llvm-profdata` format into a memory buffer and for interacting with |
| the code instrumentation generated by the compiler. |
