file named dynimportfail. The _cgo_import.go file is only needed when
using internal linking mode, which is not the default when linking
programs that use cgo (as described below). If the linker sees a file
named dynimportfail it reports an error if it has been told to use
internal linking mode. This approach is taken because generating
_cgo_import.go requires doing a full C link of the package, which can

	// uncompressed expected content.
	// If content is very large, an alternative to setting Content or File
	// is to set Size, which will then be checked against the header-reported size
	// but will bypass the decompressing of the actual data.
	// This last option is used for testing very large (multi-GB) compressed files.
	ContentErr error
	Content    []byte
	File       string
	Size       uint64

Next, any deferred functions run by <code>F's</code> caller are run,
and so on up to any deferred by the top-level function in the executing goroutine.
At that point, the program is terminated and the error
condition is reported, including the value of the argument to <code>panic</code>.
This termination sequence is called <i>panicking</i>.

(Older toolchains ignore `//go:debug` directives entirely.)

The defaults that will be compiled into a main package
are reported by the command:

{{raw `
	go list -f '{{.DefaultGODEBUG}}' my/main/package
`}}

Only differences from the base Go toolchain defaults are reported.

When testing a package, `//go:debug` lines in the `*_test.go`
files are treated as directives for the test's main package.
