示例1: dwarfFromPE

// Adapted from src/debug/pe/file.go: pe.(*File).DWARF()
func dwarfFromPE(f *pe.File) (*dwarf.Data, error) {
	// There are many other DWARF sections, but these
	// are the ones the debug/dwarf package uses.
	// Don't bother loading others.
	var names = [...]string{"abbrev", "info", "line", "str"}
	var dat [len(names)][]byte
	for i, name := range names {
		name = ".debug_" + name
		s := f.Section(name)
		if s == nil {
			continue
		}
		b, err := s.Data()
		if err != nil && uint32(len(b)) < s.Size {
			return nil, err
		}
		if 0 < s.VirtualSize && s.VirtualSize < s.Size {
			b = b[:s.VirtualSize]
		}
		dat[i] = b
	}

	abbrev, info, line, str := dat[0], dat[1], dat[2], dat[3]
	return dwarf.New(abbrev, nil, nil, info, line, nil, nil, str)
