go/packages: pass -pgo=off on go1.21 and later PGO variants can be costly to compute, and can result in unnecessary packages for the caller. They are also unlikely to be useful. Disable these variants by default, setting -pgo=off on go1.21 and later. If someone wants to see PGO variants we can have a NeedPGO flag, but that should be a separate proposal.

This repository provides the
golang.org/x/tools module, comprising various tools and packages mostly for static analysis of Go programs, some of which are listed below. Use the “Go reference” link above for more information about any package.
It also contains the
golang.org/x/tools/gopls module, whose root package is a language-server protocol (LSP) server for Go. An LSP server analyses the source code of a project and responds to requests from a wide range of editors such as VSCode and Vim, allowing them to support IDE-like functionality.
cmd/goimportsformats a Go program like
go fmtand additionally inserts import statements for any packages required by the file after it is edited.
cmd/callgraphprints the call graph of a Go program.
cmd/digraphis a utility for manipulating directed graphs in textual notation.
cmd/stringergenerates declarations (including a
Stringmethod) for “enum” types.
cmd/toolstashis a utility to simplify working with multiple versions of the Go toolchain.
These commands may be fetched with a command such as
go install golang.org/x/tools/cmd/goimports@latest
go/ssa provides a static single-assignment form (SSA) intermediate representation (IR) for Go programs, similar to a typical compiler, for use by analysis tools.
go/packages provides a simple interface for loading, parsing, and type checking a complete Go program from source code.
go/analysis provides a framework for modular static analysis of Go programs.
go/callgraph provides call graphs of Go programs using a variety of algorithms with different trade-offs.
go/ast/inspector provides an optimized means of traversing a Go parse tree for use in analysis tools.
go/cfg provides a simple control-flow graph (CFG) for a Go function.
go/expect reads Go source files used as test inputs and interprets special comments within them as queries or assertions for testing.
go/gccgoexportdata read and write the binary files containing type information used by the standard and
go/types/objectpath provides a stable naming scheme for named entities (“objects”) in the
Numerous other packages provide more esoteric functionality.
