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 {
