   8 # ISSUE(76038): When targeting MSVC, Rust binaries built with both `-Z instrument-coverage` and
   9 # `-C link-dead-code` typically crash (with a seg-fault) or at best generate an empty `*.profraw`
  10 # file, required for coverage reports.
  11 #
  12 # Enabling `-C link-dead-code` is not necessary when compiling with `-Z instrument-coverage`,
  13 # due to improvements in the coverage map generation, to add unreachable functions known to Rust.
  14 # Therefore, `-C link-dead-code` is no longer automatically enabled.
