Thanks for working on this!



================
Comment at: llvm/tools/llvm-cov/CoverageExporterJson.cpp:158
+    NumThreads = std::max(1U, std::min(llvm::heavyweight_hardware_concurrency(),
+                                       unsigned(SourceFiles.size())));
+  }
----------------
Can the parallelism be controlled by -num-threads/-j, similar to: https://llvm.org/docs/CommandGuide/llvm-cov.html#cmdoption-llvm-cov-show-num-threads

This will help write a test that the output from e.g. `-j 4` matches the output from `-j 1`.
