type GccgoInstallation

type GccgoInstallation struct {
	// Version of gcc (e.g. 4.8.0).
	GccVersion string

	// Target triple (e.g. x86_64-unknown-linux-gnu).
	TargetTriple string

	// Built-in library paths used by this installation.
	LibPaths []string

Information about a specific installation of gccgo.

func (*GccgoInstallation) GetImporter

func (inst *GccgoInstallation) GetImporter(incpaths []string, initmap map[*types.Package]InitData) Importer

Return an importer that searches incpaths followed by the gcc installation's built-in search paths and the current directory.

func (*GccgoInstallation) InitFromDriver

func (inst *GccgoInstallation) InitFromDriver(gccgoPath string, args ...string) (err error)

Ask the driver at the given path for information for this GccgoInstallation. The given arguments are passed directly to the call of the driver.

func (*GccgoInstallation) SearchPaths

func (inst *GccgoInstallation) SearchPaths() (paths []string)

Return the list of export search paths for this GccgoInstallation.

type Importer

type Importer func(imports map[string]*types.Package, path, srcDir string, lookup func(string) (io.ReadCloser, error)) (*types.Package, error)

An Importer resolves import paths to Packages. The imports map records packages already known, indexed by package path. An importer must determine the canonical package path and check imports to see if it is already present in the map. If so, the Importer can return the map entry. Otherwise, the importer must load the package data for the given path into a new *Package, record it in imports map, and return the package.

func GetImporter

func GetImporter(searchpaths []string, initmap map[*types.Package]InitData) Importer

type InitData

type InitData struct {
	// Initialization priority of this package relative to other packages.
	// This is based on the maximum depth of the package's dependency graph;
	// it is guaranteed to be greater than that of its dependencies.
	Priority int

	// The list of packages which this package depends on to be initialized,
	// including itself if needed. This is the subset of the transitive closure of
	// the package's dependencies that need initialization.
	Inits []PackageInit

The gccgo-specific init data for a package.

type PackageInit

type PackageInit struct {
	Name     string // short package name
	InitFunc string // name of init function
	Priority int    // priority of init function, see InitData.Priority

A PackageInit describes an imported package that needs initialization.
