The extra functions here are stubs to satisfy the references in the C
code generated for gcc. The build process links this stub, along with
_cgo_export.c and *.cgo2.c, into a dynamic executable and then lets
cgo examine the executable. Cgo records the list of shared library
references and resolved names and writes them into a new file
_cgo_import.go, which looks like:

	{"[X0,X1,X2,X3]", "register list: expected '-' after `[X0`, found ','"},
	{"$foo<ABI0>", "ABI selector only permitted when compiling runtime, reference was to \"foo\""},
}

var amd64BadOperandRuntimeTests = []badOperandTest{
	{"$foo<bletch>", "malformed ABI selector \"bletch\" in reference to \"foo\""},
}

var x86OperandTests = []operandTest{
	{"$(2.928932188134524e-01)", "$(0.29289321881345243)"},
	{"$-1", "$-1"},

The new [unique](/pkg/unique) package provides facilities for
canonicalizing values (like "interning" or "hash-consing").

Any value of comparable type may be canonicalized with the new
`Make[T]` function, which produces a reference to a canonical copy of
the value in the form of a `Handle[T]`.
Two `Handle[T]` are equal if and only if the values used to produce the
handles are equal, allowing programs to deduplicate values and reduce
their memory footprint.
