Only honor //go:build language version downgrades if the version specified is 1.21 or greater. Before 1.21 the version in //go:build lines didn't have the meaning of setting the file's language version. This fixes an issue that was appearing in GOPATH builds: Go 1.23 started providing -lang versions to the compiler in GOPATH mode (among other places) which it wasn't doing before. For example, take a go file with a //go:build line specifying go1.10. If that file used a 1.18 feature, that use would compile fine with a Go 1.22 toolchain. But, before this change, it would produce an error when compiling with the 1.23 toolchain because it set the language version to 1.10 and disallowed the 1.18 feature. This breaks backwards compatibility: when the build tag was added, it did not have the meaning of restricting the language version.

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.
To run just these tests, execute:
../bin/go test cmd/internal/testdir
To run just tests from specified files in this directory, execute:
../bin/go test cmd/internal/testdir -run='Test/(file1.go|file2.go|...)'
Standard library tests should be written as regular Go tests in the appropriate package.
The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:
- it is most naturally expressed using the test runner; or
- it is also applicable to
gccgoand other Go tool chains.
