Package Files

disasm.go elf.go goobj.go macho.go objfile.go pe.go plan9obj.go

type Disasm Uses

type Disasm struct {
    // contains filtered or unexported fields

Disasm is a disassembler for a given File.

func (*Disasm) Decode Uses

func (d *Disasm) Decode(start, end uint64, f func(pc, size uint64, file string, line int, text string))

Decode disassembles the text segment range [start, end), calling f for each instruction.

func (*Disasm) Print Uses

func (d *Disasm) Print(w io.Writer, filter *regexp.Regexp, start, end uint64)

Print prints a disassembly of the file to w. If filter is non-nil, the disassembly only includes functions with names matching filter. The disassembly only includes functions that overlap the range [start, end).

type File Uses

type File struct {
    // contains filtered or unexported fields

A File is an opened executable file.

func Open Uses

func Open(name string) (*File, error)

Open opens the named file. The caller must call f.Close when the file is no longer needed.

func (*File) Close Uses

func (f *File) Close() error

func (*File) DWARF Uses

func (f *File) DWARF() (*dwarf.Data, error)

DWARF returns DWARF debug data for the file, if any. This is for cmd/pprof to locate cgo functions.

func (*File) Disasm Uses

func (f *File) Disasm() (*Disasm, error)

Disasm returns a disassembler for the file f.

func (*File) GOARCH Uses

func (f *File) GOARCH() string

func (*File) LoadAddress Uses

func (f *File) LoadAddress() (uint64, error)

LoadAddress returns the expected load address of the file. This differs from the actual load address for a position-independent executable.

func (*File) PCLineTable Uses

func (f *File) PCLineTable() (*gosym.Table, error)

func (*File) Symbols Uses

func (f *File) Symbols() ([]Sym, error)

func (*File) Text Uses

func (f *File) Text() (uint64, []byte, error)

type Sym Uses

type Sym struct {
    Name string // symbol name
    Addr uint64 // virtual address of symbol
    Size int64  // size in bytes
    Code rune   // nm code (T for text, D for data, and so on)
    Type string // XXX?

A Sym is a symbol defined in an executable file.
