Please excuse the reply to self, but I have discovered what I was missing.
For the sake of completeness, here is how the equivalent mapping is
achieved in golang.org/x/tools/go/loader world:
import (
"go/ast"
"go/parser"
"golang.org/x/tools/go/loader"
)
conf := loader.Config{
ParserMode: parser.AllErrors | parser.ParseComments,
Cwd: path,
}
...
conf.CreateFromFilenames(path, toParse...)
prog, err := conf.Load()
if err != nil {
panic(err)
}
At this point conf.CreatePkgs (type []loader.PkgSpec) and prog.Created
(type []*loader.PackageInfo) correspond to each other.
For each (loader.PkgSpec, *loader.PackageInfo) pairing, say pkgSpec and
pkgInfo, then pkgSpec.Filenames (type []string) and pkgInfo (type
[]*ast.File) again correspond, which gives us the required mapping.
