Russ Cox 2fba42cb52 cmd/compile: implement range over func
Add compiler support for range over functions.
See the large comment at the top of
cmd/compile/internal/rangefunc/rewrite.go for details.

This is only reachable if GOEXPERIMENT=range is set,
because otherwise type checking will fail.

For proposal #61405 (but behind a GOEXPERIMENT).
For #61717.

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.
