We are converting from using error-prone ad-hoc syntax // +build lines to less error-prone, standard boolean syntax //go:build lines. The timeline is: Go 1.16: prepare for transition - Builds still use // +build for file selection. - Source files may not contain //go:build without // +build. - Builds fail when a source file contains //go:build lines without // +build lines. <<< Go 1.17: start transition - Builds prefer //go:build for file selection, falling back to // +build for files containing only // +build. - Source files may contain //go:build without // +build (but they won't build with Go 1.16). - Gofmt moves //go:build and // +build lines to proper file locations. - Gofmt introduces //go:build lines into files with only // +build lines. - Go vet rejects files with mismatched //go:build and // +build lines. Go 1.18: complete transition - Go fix removes // +build lines, leaving behind equivalent // +build lines. This CL provides part of the <<< marked line above in the Go 1.16 step: rejecting files containing //go:build but not // +build. The standard go command checks only consider the top of the file. This compiler check, along with a separate go vet check for ignored files, handles the remainder of the file. For #41184.
