double-quoted strings passed to the generator as individual
arguments when it is run.

Quoted strings use Go syntax and are evaluated before execution; a
quoted string appears as a single argument to the generator.

To convey to humans and machine tools that code is generated,
generated source should have a line that matches the following
regular expression (in Go syntax):

	^// Code generated .* DO NOT EDIT\.$

	init.Append(as)
	return res
}

// Returns the data word (the second word) used to represent conv.X in
// an interface.
func dataWord(conv *ir.ConvExpr, init *ir.Nodes) ir.Node {
	pos, n := conv.Pos(), conv.X
	fromType := n.Type()

	// If it's a pointer, it is its own representation.
	if types.IsDirectIface(fromType) {
		return n
	}

//			significantly more expensive.
//		Sets -cover.
//	-coverpkg pattern1,pattern2,pattern3
//		For a build that targets package 'main' (e.g. building a Go
//		executable), apply coverage analysis to each package matching
//		the patterns. The default is to apply coverage analysis to
//		packages in the main Go module. See 'go help packages' for a
//		description of package patterns.  Sets -cover.
//	-v

	args = append(args, cmdline...)
	return b.Shell(a).runOut(a.Objdir, nil, args)
}

// BuildActionCoverMetaFile locates and returns the path of the
// meta-data file written by the "go tool cover" step as part of the
// build action for the "go test -cover" run action 'runAct'. Note
// that if the package has no functions the meta-data file will exist
// but will be empty; in this case the return is an empty string.

With the -find flag, the -deps, -test and -export commands cannot be
used.

The -test flag causes list to report not only the named packages
but also their test binaries (for packages with tests), to convey to
source code analysis tools exactly how test binaries are constructed.
The reported import path for a test binary is the import path of
the package followed by a ".test" suffix, as in "math/rand.test".

Cover is a program for analyzing the coverage profiles generated by
'go test -coverprofile=cover.out'.

Cover is also used by 'go test -cover' to rewrite the source code with
annotations to track which parts of each function are executed (this
is referred to "instrumentation"). Cover can operate in "legacy mode"
