package race

// This file merely ensures that we link in runtime/cgo in race build,
// this in turn ensures that runtime uses pthread_create to create threads.
// 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.
