You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: backdoor.go
    path of file: ./repos/gitkube/vendor/golang.org/x/tools/go/internal/gccgoimporter
    
    the code of the file until where you have to start completion: package gccgoimporter

// This file opens a back door to the parser for golang.org/x/tools/go/gccgoexportdata.

import (
	"go/types"
	"io"
)

// Parse reads and parses gccgo export data from in and constructs a
// Package, inserting it into the imports map.
func Parse(in io.Reader, imports map[string]
    
func Parse(in io.Reader, imports map[string]*types.Package, path string) (_ *types.Package, err error) {
	var p parser
	p.init(path, in, imports)
	defer func() {
		switch x := recover().(type) {
		case nil:
			// success
		case importError:
			err = x
		default:
			panic(x) // resume unexpected panic
		}
	}()
	pkg := p.parsePackage()
	imports[path] = pkg
	return pkg, err
}
