-// Stringer is a tool to automate the creation of methods that satisfy the fmt.Stringer
-// interface. Given the name of a (signed or unsigned) integer type T that has constants
-// defined, stringer will create a new self-contained Go source file implementing
-//
-//	func (t T) String() string
-//
-// The file is created in the same package and directory as the package that defines T.
-// It has helpful defaults designed for use with go generate.
-//
-// Stringer works best with constants that are consecutive values such as created using iota,
-// but creates good code regardless. In the future it might also provide custom support for
-// constant sets that are bit patterns.
-//
-// For example, given this snippet,
-//
-//	package painkiller
-//
-//	type Pill int
-//
-//	const (
-//		Placebo Pill = iota
-//		Aspirin
-//		Ibuprofen
-//		Paracetamol
-//		Acetaminophen = Paracetamol
-//	)
-//
-// running this command
-//
-//	stringer -type=Pill
-//
-// in the same directory will create the file pill_string.go, in package painkiller,
-// containing a definition of
-//
-//	func (Pill) String() string
-//
-// That method will translate the value of a Pill constant to the string representation
-// of the respective constant name, so that the call fmt.Print(painkiller.Aspirin) will
-// print the string "Aspirin".
-//
-// Typically this process would be run using go generate, like this:
-//
-//	//go:generate stringer -type=Pill
-//
-// If multiple constants have the same value, the lexically first matching name will
-// be used (in the example, Acetaminophen will print as "Paracetamol").
-//
-// With no arguments, it processes the package in the current directory.
-// Otherwise, the arguments must name a single directory holding a Go package
-// or a set of Go source files that represent a single Go package.
-//
-// The -type flag accepts a comma-separated list of types so a single run can
-// generate methods for multiple types. The default output file is t_string.go,
-// where t is the lower-cased name of the first type listed. It can be overridden
-// with the -output flag.
-//
-// The -linecomment flag tells stringer to generate the text of any line comment, trimmed
-// of leading spaces, instead of the constant name. For instance, if the constants above had a
-// Pill prefix, one could write
-//
-//	PillAspirin // Aspirin
-//
-// to suppress it in the output.

-Package packages loads Go packages for inspection and analysis.
-
-The Load function takes as input a list of patterns and return a list of Package
-structs describing individual packages matched by those patterns.
-The LoadMode controls the amount of detail in the loaded packages.
-
-Load passes most patterns directly to the underlying build tool,
-but all patterns with the prefix "query=", where query is a
-non-empty string of letters from [a-z], are reserved and may be
-interpreted as query operators.
-
-Two query operators are currently supported: "file" and "pattern".
-
-The query "file=path/to/file.go" matches the package or packages enclosing
-the Go source file path/to/file.go.  For example "file=~/go/src/fmt/print.go"
-might return the packages "fmt" and "fmt [fmt.test]".
-
-The query "pattern=string" causes "string" to be passed directly to
-the underlying build tool. In most cases this is unnecessary,
-but an application can use Load("pattern=" + x) as an escaping mechanism
-to ensure that x is not interpreted as a query operator if it contains '='.
-
-All other query operators are reserved for future use and currently
-cause Load to report an error.
-
-The Package struct provides basic information about the package, including
-
-  - ID, a unique identifier for the package in the returned set;
-  - GoFiles, the names of the package's Go source files;
-  - Imports, a map from source import strings to the Packages they name;
-  - Types, the type information for the package's exported symbols;
-  - Syntax, the parsed syntax trees for the package's source code; and
-  - TypesInfo, the result of a complete type-check of the package syntax trees.
-
-(See the documentation for type Package for the complete list of fields
-and more detailed descriptions.)
-
-For example,
-
-	Load(nil, "bytes", "unicode...")
-
-returns four Package structs describing the standard library packages
-bytes, unicode, unicode/utf16, and unicode/utf8. Note that one pattern
-can match multiple packages and that a package might be matched by
-multiple patterns: in general it is not possible to determine which
-packages correspond to which patterns.
-
-Note that the list returned by Load contains only the packages matched
-by the patterns. Their dependencies can be found by walking the import
-graph using the Imports fields.
-
-The Load function can be configured by passing a pointer to a Config as
-the first argument. A nil Config is equivalent to the zero Config, which
-causes Load to run in LoadFiles mode, collecting minimal information.
-See the documentation for type Config for details.
-
-As noted earlier, the Config.Mode controls the amount of detail
-reported about the loaded packages. See the documentation for type LoadMode
-for details.
-
-Most tools should pass their command-line arguments (after any flags)
-uninterpreted to the loader, so that the loader can interpret them
-according to the conventions of the underlying build system.
-See the Example function for typical usage.

-
-Motivation and design considerations
-
-The new package's design solves problems addressed by two existing
-packages: go/build, which locates and describes packages, and
-golang.org/x/tools/go/loader, which loads, parses and type-checks them.
-The go/build.Package structure encodes too much of the 'go build' way
-of organizing projects, leaving us in need of a data type that describes a
-package of Go source code independent of the underlying build system.
-We wanted something that works equally well with go build and vgo, and
-also other build systems such as Bazel and Blaze, making it possible to
-construct analysis tools that work in all these environments.
-Tools such as errcheck and staticcheck were essentially unavailable to
-the Go community at Google, and some of Google's internal tools for Go
-are unavailable externally.
-This new package provides a uniform way to obtain package metadata by
-querying each of these build systems, optionally supporting their
-preferred command-line notations for packages, so that tools integrate
-neatly with users' build environments. The Metadata query function
-executes an external query tool appropriate to the current workspace.
-
-Loading packages always returns the complete import graph "all the way down",
-even if all you want is information about a single package, because the query
-mechanisms of all the build systems we currently support ({go,vgo} list, and
-blaze/bazel aspect-based query) cannot provide detailed information
-about one package without visiting all its dependencies too, so there is
-no additional asymptotic cost to providing transitive information.
-(This property might not be true of a hypothetical 5th build system.)
-
-In calls to TypeCheck, all initial packages, and any package that
-transitively depends on one of them, must be loaded from source.
-Consider A->B->C->D->E: if A,C are initial, A,B,C must be loaded from
-source; D may be loaded from export data, and E may not be loaded at all
-(though it's possible that D's export data mentions it, so a
-types.Package may be created for it and exposed.)
-
-The old loader had a feature to suppress type-checking of function
-bodies on a per-package basis, primarily intended to reduce the work of
-obtaining type information for imported packages. Now that imports are
-satisfied by export data, the optimization no longer seems necessary.
-
-Despite some early attempts, the old loader did not exploit export data,
-instead always using the equivalent of WholeProgram mode. This was due
-to the complexity of mixing source and export data packages (now
-resolved by the upward traversal mentioned above), and because export data
-files were nearly always missing or stale. Now that 'go build' supports
-caching, all the underlying build systems can guarantee to produce
-export data in a reasonable (amortized) time.
-
-Test "main" packages synthesized by the build system are now reported as
-first-class packages, avoiding the need for clients (such as go/ssa) to
-reinvent this generation logic.
-
-One way in which go/packages is simpler than the old loader is in its
-treatment of in-package tests. In-package tests are packages that
-consist of all the files of the library under test, plus the test files.
-The old loader constructed in-package tests by a two-phase process of
-mutation called "augmentation": first it would construct and type check
-all the ordinary library packages and type-check the packages that
-depend on them; then it would add more (test) files to the package and
-type-check again. This two-phase approach had four major problems:
-1) in processing the tests, the loader modified the library package,
-   leaving no way for a client application to see both the test
-   package and the library package; one would mutate into the other.
-2) because test files can declare additional methods on types defined in
-   the library portion of the package, the dispatch of method calls in
-   the library portion was affected by the presence of the test files.
-   This should have been a clue that the packages were logically
-   different.
-3) this model of "augmentation" assumed at most one in-package test
-   per library package, which is true of projects using 'go build',
-   but not other build systems.
-4) because of the two-phase nature of test processing, all packages that
-   import the library package had to be processed before augmentation,
-   forcing a "one-shot" API and preventing the client from calling Load
-   in several times in sequence as is now possible in WholeProgram mode.
-   (TypeCheck mode has a similar one-shot restriction for a different reason.)
-
-Early drafts of this package supported "multi-shot" operation.
-Although it allowed clients to make a sequence of calls (or concurrent
-calls) to Load, building up the graph of Packages incrementally,
-it was of marginal value: it complicated the API
-(since it allowed some options to vary across calls but not others),
-it complicated the implementation,
-it cannot be made to work in Types mode, as explained above,
-and it was less efficient than making one combined call (when this is possible).
-Among the clients we have inspected, none made multiple calls to load
-but could not be easily and satisfactorily modified to make only a single call.
-However, applications changes may be required.
-For example, the ssadump command loads the user-specified packages
-and in addition the runtime package.  It is tempting to simply append
-"runtime" to the user-provided list, but that does not work if the user
-specified an ad-hoc package such as [a.go b.go].
-Instead, ssadump no longer requests the runtime package,
-but seeks it among the dependencies of the user-specified packages,
-and emits an error if it is not found.
-
-Overlays: The Overlay field in the Config allows providing alternate contents
-for Go source files, by providing a mapping from file path to contents.
-go/packages will pull in new imports added in overlay files when go/packages
-is run in LoadImports mode or greater.
-Overlay support for the go list driver isn't complete yet: if the file doesn't
-exist on disk, it will only be recognized in an overlay if it is a non-test file
-and the package would be reported even without the overlay.
-
-Questions & Tasks
-
-- Add GOARCH/GOOS?
-  They are not portable concepts, but could be made portable.
-  Our goal has been to allow users to express themselves using the conventions
-  of the underlying build system: if the build system honors GOARCH
-  during a build and during a metadata query, then so should
-  applications built atop that query mechanism.
-  Conversely, if the target architecture of the build is determined by
-  command-line flags, the application can pass the relevant
-  flags through to the build system using a command such as:
-    myapp -query_flag="--cpu=amd64" -query_flag="--os=darwin"
-  However, this approach is low-level, unwieldy, and non-portable.
-  GOOS and GOARCH seem important enough to warrant a dedicated option.
-
-- How should we handle partial failures such as a mixture of good and
-  malformed patterns, existing and non-existent packages, successful and
-  failed builds, import failures, import cycles, and so on, in a call to
-  Load?
-
-- Support bazel, blaze, and go1.10 list, not just go1.11 list.
-
-- Handle (and test) various partial success cases, e.g.
-  a mixture of good packages and:
-  invalid patterns
-  nonexistent packages
-  empty packages
-  packages with malformed package or import declarations
-  unreadable files
-  import cycles
-  other parse errors
-  type errors
-  Make sure we record errors at the correct place in the graph.
-
-- Missing packages among initial arguments are not reported.
-  Return bogus packages for them, like golist does.
-
-- "undeclared name" errors (for example) are reported out of source file
-  order. I suspect this is due to the breadth-first resolution now used
-  by go/types. Is that a bug? Discuss with gri.

-//   - The TT operators are encoded as [EKPRUTC];
-//     one of these (TypeParam) requires an integer operand,
-//     which is encoded as a string of decimal digits.
-//   - The TO operators are encoded as [AFMO];

-// Package pkgbits implements low-level coding abstractions for
-// Unified IR's export data format.
-//
-// At a low-level, a package is a collection of bitstream elements.
-// Each element has a "kind" and a dense, non-negative index.
-// Elements can be randomly accessed given their kind and index.
-//
-// Individual elements are sequences of variable-length values (e.g.,
-// integers, booleans, strings, go/constant values, cross-references
-// to other elements). Package pkgbits provides APIs for encoding and
-// decoding these low-level values, but the details of mapping
-// higher-level Go constructs into elements is left to higher-level
-// abstractions.
-//
-// Elements may cross-reference each other with "relocations." For
-// example, an element representing a pointer type has a relocation
-// referring to the element type.
-//
-// Go constructs may be composed as a constellation of multiple
-// elements. For example, a declared function may have one element to
-// describe the object (e.g., its name, type, position), and a
-// separate element to describe its function body. This allows readers
-// some flexibility in efficiently seeking or re-reading data (e.g.,
-// inlining requires re-reading the function body for each inlined
-// call, without needing to re-read the object-level details).
-//

-// Because the minimal representation always takes this form, _NormalTerms
