Types

type DwarfLiner

type DwarfLiner struct {
	// contains filtered or unexported fields
}

DwarfLiner is a symbolizer that uses DWARF debug info to symbolize addresses.

func DWARF

func DWARF(logger log.Logger, f *elf.File, demangler *demangle.Demangler) (*DwarfLiner, error)

DWARF creates a new DwarfLiner.

func (*DwarfLiner) PCToLines

func (dl *DwarfLiner) PCToLines(addr uint64) (lines []profile.LocationLine, err error)

PCToLines returns the resolved source lines for a program counter (memory address).

type GoLiner

type GoLiner struct {
	// contains filtered or unexported fields
}

GoLiner is a liner which utilizes .gopclntab section to symbolize addresses. It doesn't work for inlined functions.

func Go

func Go(logger log.Logger, f *elf.File) (*GoLiner, error)

Go creates a new GoLiner.

func (*GoLiner) PCToLines

func (gl *GoLiner) PCToLines(addr uint64) (lines []profile.LocationLine, err error)

PCToLines looks up the line number information for a program counter (memory address).

type SymtabLiner

type SymtabLiner struct {
	// contains filtered or unexported fields
}

SymtabLiner is a liner which utilizes .symtab and .dynsym sections.

func Symbols

func Symbols(logger log.Logger, f *elf.File, demangler *demangle.Demangler) (*SymtabLiner, error)

Symbols creates a new SymtabLiner.

func (*SymtabLiner) PCToLines

func (lnr *SymtabLiner) PCToLines(addr uint64) (lines []profile.LocationLine, err error)

PCToLines looks up the line number information for a program counter (memory address).
