Alan Donovan be28dbb86f go.types/ssa: split the load/parse/typecheck logic off into a separate package. ... PLEASE NOTE: the APIs for both "importer" and "ssa" packages will continue to evolve and both need some polishing; the key thing is that this CL splits them. The go.types/importer package contains contains the Importer, which takes care of the mechanics of loading a set of packages and type-checking them. It exposes for each package a PackageInfo containing: - the package's ASTs (i.e. the input to the typechecker) - the types.Package object - the memoization of the typechecker callbacks for identifier resolution, constant folding and expression type inference. Method-set computation (and hence bridge-method creation) is now moved to after creation of all packages: since they are no longer created in topological order, we can't guarantee the needed delegate methods exist yet. ssa.Package no longer has public TypeOf, ObjectOf, ValueOf methods. The private counterparts are valid only during the build phase. Also: - added to go/types an informative error (not crash) for an importer() returning nil without error. - removed Package.Name(), barely needed. - changed Package.String() slightly. - flag what looks like a bug in makeBridgeMethod. Will follow up. R=golang-dev, gri CC=golang-dev https://golang.org/cl/9898043		2013-05-31 16:14:13 -04:00
