Michael Pratt 3fb8b4f3db all: move //go:debug decoratemappings=0 test to cmd/go
test/decoratemappingszero.go is intended to test that
//go:debug decoratemappings=0 disables annonations.

Unfortunately, //go:debug processing is handled by cmd/go, but
cmd/internal/testdir (which runs tests from test/) generally invokes the
compiler directly, thus it does not set default GODEBUGs.

Move this test to the cmd/go script tests, alongside the similar test
for language version.

Fixes #72772.

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 gccgo and other Go tool chains.
