     9  // This file merely ensures that we link in runtime/cgo in race build,
    10  // this in turn ensures that runtime uses pthread_create to create threads.
    11  // The prebuilt race runtime lives in race_GOOS_GOARCH.syso.
    12  // Calls to the runtime are done directly from src/runtime/race.go.

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