// kernel version 21.3.0 (MacOS 12.2.0) or later (see issue 49233).
//
// Background:
// Darwin implements a special mechanism to economize on thread state when
// AVX512 specific registers are not in use. This scheme minimizes state when
// preempting threads that haven't yet used any AVX512 instructions, but adds
// special requirements to check for AVX512 hardware support at runtime (e.g.
// via sysctl call or commpage inspection). See issue 43089 and link below for
// full background:
// https://github.com/apple-oss-distributions/xnu/blob/xnu-11215.1.10/osfmk/i386/fpu.c#L214-L240
//
// Additionally, all versions of the Darwin kernel from 19.6.0 through 21.2.0
// (corresponding to MacOS 10.15.6 - 12.1) have a bug that can cause corruption
// of the AVX512 mask registers (K0-K7) upon signal return. For this reason

//
// Although it might seem convenient for this package to live alongside

// problems for developer tools that use it, since they must be able to
// consume the outputs of the gc compiler both before and after a Go
// update such as from Go 1.7 to Go 1.8. Because this package lives in
// golang.org/x/tools, sites can update their version of this repo some
// time before the Go 1.8 release and rebuild and redeploy their

// Go 1.8 export data files, so they will work before and after the
// Go update. (See discussion at https://golang.org/issue/15651.)

// The standard Go compiler (cmd/compile) writes an export data file
// for each package it compiles, which it later reads when compiling
// packages that import the earlier one. The compiler must thus
// contain logic to both write and read export data.
// (See the "Export" section in the cmd/compile/README file.)
//
// The [Read] function in this package can read files produced by the
// compiler, producing [go/types] data structures. As a matter of
// policy, Read supports export data files produced by only the last
// two Go releases plus tip; see https://go.dev/issue/68898. The
// export data files produced by the compiler contain additional
// details related to generics, inlining, and other optimizations that
// cannot be decoded by the [Read] function.
//
// In files written by the compiler, the export data is not at the
// start of the file. Before calling Read, use [NewReader] to locate
// the desired portion of the file.
//
// The [Write] function in this package encodes the exported API of a
// Go package ([types.Package]) as a file. Such files can be later
// decoded by Read, but cannot be consumed by the compiler.
//
// # Future changes
//
// Although Read supports the formats written by both Write and the
// compiler, the two are quite different, and there is an open
// proposal (https://go.dev/issue/69491) to separate these APIs.
//
// Under that proposal, this package would ultimately provide only the
// Read operation for compiler export data, which must be defined in
// this module (golang.org/x/tools), not in the standard library, to
// avoid version skew for developer tools that need to read compiler
// export data both before and after a Go release, such as from Go
// 1.23 to Go 1.24. Because this package lives in the tools module,
// clients can update their version of the module some time before the
// Go 1.24 release and rebuild and redeploy their tools, which will
// then be able to consume both Go 1.23 and Go 1.24 export data files,
// so they will work before and after the Go update. (See discussion

//
// The [NewImporter] and [Find] functions are deprecated and should
// not be used in new code. The [WriteBundle] and [ReadBundle]
// functions are experimental, and there is an open proposal to

// content of their own, merely because they mention a major type that
// references many others. In pathological cases the export data was
// 300x larger than the source for a package due to this quadratic
// growth.

// "Shallow" export data means that the serialized types describe only
// a single package. If those types mention types from other packages,
// the type checker may need to request additional packages beyond
