Command goimports updates your Go import lines, adding missing ones and removing unreferenced ones.

The gotype command does syntactic and semantic analysis of Go files and packages like the front-end of a Go compiler.

Package intsets provides Sparse, a compact and fast representation for sparse sets of int values.

Package astutil contains common utilities for working with the Go AST.

Package buildutil provides utilities related to the go/build package in the standard library.

Package callgraph defines the call graph and various algorithms and utilities to operate on it.

Package cha computes the call graph of a Go program using the Class Hierarchy Analysis (CHA) algorithm.

This package provides Rapid Type Analysis (RTA) for Go, a fast algorithm for call graph construction and discovery of reachable code (and hence dead code) and runtime types.

Package static computes the call graph of a Go program containing only static call edges.

Package gcexportdata provides functions for locating, reading, and writing export data files containing type information produced by the gc compiler.

Package gcimporter15 provides various functions for reading gc-generated object files that can be used to implement the Importer interface defined by the Go 1.5 standard library package.

Package loader loads a complete Go program from source code, parsing and type-checking the initial packages plus their transitive closure of dependencies.

Package pointer implements Andersen's analysis, an inclusion-based pointer analysis algorithm first described in (Andersen, 1994).

Package ssa defines a representation of the elements of Go programs (packages, types, functions, variables and constants) using a static single-assignment (SSA) form intermediate representation (IR) for the bodies of functions.

Package ssa/interp defines an interpreter for the SSA representation of Go programs.

Package typeutil defines various utilities for types, such as Map, a mapping from types.Type to interface{} values.
