| // The prebuilt race runtime lives in race_GOOS_GOARCH.syso. |
| // Calls to the runtime are done directly from src/runtime/race.go. |

| // On darwin we always use system DLLs to create threads, |
| // so we use race_darwin_$GOARCH.go to provide the syso-derived |
| // symbol information without needing to invoke cgo. |
| // This allows -race to be used on Mac systems without a C toolchain. |
