[PATCH] D78408: [llvm-cov] Prevent llvm-cov from using too many threads

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

I think we should respect ThreadsRequested if it is greater than 0.

For the particular llvm-cov issue, we can probably restore the previous behavior:

  NumThreads =
      std::max(1U, std::min(llvm::heavyweight_hardware_concurrency(),
                            unsigned(SourceFiles.size())));
  NumThreads = SourceFiles.size();
