We are using a code generator that replaces the source code with generated code before feeding to the compiler. We are collecting the code coverage on the generated code so we can map it back to the original source code.
This was possible before Bazel 6, but started to fail after Bazel 6 because it comes with a newer version of coverage_output_generator, which ignores files not included in
coverage_common.instrumented_files_info
.This PR makes
coverage_common.instrumented_files_info
return both regular and generated/derived source files.
