### Go command {#go-command}

Setting the `GOROOT_FINAL` environment variable no longer has an effect
([#62047](https://go.dev/issue/62047)).
Distributions that install the `go` command to a location other than
`$GOROOT/bin/go` should install a symlink instead of relocating
or copying the `go` binary.

### Vet {#vet}

The `go vet` subcommand now includes the

    id: gopls-version
    attributes:
      label: "gopls version"
      description: "Output of `gopls -v version` on the command line"
    validations:
      required: true
  - type: textarea
    id: go-env
    attributes:
      label: "go env"
      description: "Output of `go env` on the command line in your workspace directory"

file named for the basename of the argument source file with a .o suffix. The
object file can then be combined with other objects into a package archive.

# Command Line

Usage:

	go tool asm [flags] file

The specified file must be a Go assembly file.
The same assembler is used for all target operating systems and architectures.

		includes:        append([]string{filepath.Dir(name)}, flags.I...),
		beginningOfLine: true,
		macros:          predefine(flags.D),
	}
}

// predefine installs the macros set by the -D flag on the command line.
func predefine(defines flags.MultiFlag) map[string]*Macro {
	macros := make(map[string]*Macro)
	for _, name := range defines {
		value := "1"
		i := strings.IndexRune(name, '=')
		if i > 0 {
