Package rangefunc rewrites range-over-func to code that doesn't use range-over-funcs.
Rewriting the construct in the front end, before noder, means the functions generated during
the rewrite are available in a noder-generated representation for inlining by the back end.

# Theory of Operation

The basic idea is to rewrite

	for x := range f {
		...
	}

into

// Returns pass that prepares TPU computation to be legal for export to
// TensorFlow.
std::unique_ptr<OperationPass<ModuleOp>>
CreatePrepareTpuComputationForTfExportPass();

// Rewrites ops that require quantized inputs or outputs to ops that allow
// non-quantized inputs and outputs.
std::unique_ptr<OperationPass<func::FuncOp>> CreateLowerQuantizedPass();

//
//go:linkname add
//go:nosplit
func add(p unsafe.Pointer, x uintptr) unsafe.Pointer {
	return unsafe.Pointer(uintptr(p) + x)
}

// getg returns the pointer to the current g.
// The compiler rewrites calls to this function into instructions
// that fetch the g directly (from TLS or from the dedicated register).
func getg() *g

// mcall switches from the g to the g0 stack and invokes fn(g),

	}
}

// canonicalize returns the canonical name used for a linker symbol in
// s's maps. Symbols in this package may be written either as "".X or
// with the package's import path already in the symbol. This rewrites
// both to use the full path, which matches compiler-generated linker
// symbol names.
func (s *SymABIs) canonicalize(linksym string) string {
	if strings.HasPrefix(linksym, `"".`) {

	s.currentPodSnapshot.Ensure(string(pod.UID))
	openNetns, err := s.getOrOpenNetns(pod, netNs)
	if err != nil {
		return err
	}

	// Handle node healthcheck probe rewrites
	_, err = addPodToHostNSIpset(pod, podIPs, &s.hostsideProbeIPSet)
	if err != nil {
		log.Errorf("failed to add pod to ipset: %s/%s %v", pod.Namespace, pod.Name, err)
		return err
	}

	)

	// TODO BML I don't think we need UDP? TCP healthcheck redir should catch everything.

	// This is effectively an analog for Istio's old-style podSpec-based health check rewrites.
	// Before Istio would update the pod manifest to rewrite healthchecks to go to sidecar Envoy port 15021,
	// so that it could distinguish things that can be unauthenticated (healthchecks) from other kinds of node traffic

//
// reportCmd formats the output as "# desc" followed by the given output. The
// output is expected to contain references to 'dir', usually the source
// directory for the package that has failed to build. reportCmd rewrites
// mentions of dir with a relative path to dir when the relative path is
// shorter. This is usually more pleasant. For example, if fmt doesn't compile
// and we are in src/html, the output is
//
//	$ go build

// mapinitcleanup walks all pkg init functions and looks for weak relocations
// to mapinit symbols that are no longer reachable. It rewrites
// the relocs to target a new no-op routine in the runtime.

// looking like the end of the sequence.
//
// The decoded form returned by the Reader's Read method
// rewrites the "\r\n" line endings into the simpler "\n",
// removes leading dot escapes if present, and stops with error [io.EOF]
// after consuming (and discarding) the end-of-sequence line.

// it gets inlined in the "main' function and the corresponding argument is
// removed from the signature. For resource args, their subtypes are populated.
