Functions

func InlineStack

func InlineStack(root *godwarf.Tree, pc uint64) []*godwarf.Tree

InlineStack returns the stack of inlined calls for the specified function and PC address. If pc is 0 then all inlined calls will be returned.

Types

type Reader

type Reader struct {
	*dwarf.Reader
	// contains filtered or unexported fields
}

func New

func New(data *dwarf.Data) *Reader

New returns a reader for the specified dwarf data.

func (*Reader) AddrFor

func (reader *Reader) AddrFor(name string, staticBase uint64, ptrSize int) (uint64, error)

Returns the address for the named entry.

func (*Reader) AddrForMember

func (reader *Reader) AddrForMember(member string, initialInstructions []byte, ptrSize int) (uint64, error)

Returns the address for the named struct member. Expects the reader to be at the parent entry or one of the parents children, thus does not seek to parent by itself.

func (*Reader) FindEntryNamed

func (reader *Reader) FindEntryNamed(name string, member bool) (*dwarf.Entry, error)

Finds the entry for 'name'.

func (*Reader) InstructionsForEntry

func (reader *Reader) InstructionsForEntry(entry *dwarf.Entry) ([]byte, error)

func (*Reader) InstructionsForEntryNamed

func (reader *Reader) InstructionsForEntryNamed(name string, member bool) ([]byte, error)

func (*Reader) NextCompileUnit

func (reader *Reader) NextCompileUnit() (*dwarf.Entry, error)

func (*Reader) NextMemberVariable

func (reader *Reader) NextMemberVariable() (*dwarf.Entry, error)

NextMemberVariable moves the reader to the next debug entry that describes a member variable and returns the entry.

func (*Reader) NextPackageVariable

func (reader *Reader) NextPackageVariable() (*dwarf.Entry, error)

NextPackageVariable moves the reader to the next debug entry that describes a package variable. Any TagVariable entry that is not inside a sub prgram entry and is marked external is considered a package variable.

func (*Reader) NextType

func (reader *Reader) NextType() (*dwarf.Entry, error)

func (*Reader) Seek

func (reader *Reader) Seek(off dwarf.Offset)

Seek moves the reader to an arbitrary offset.

func (*Reader) SeekToEntry

func (reader *Reader) SeekToEntry(entry *dwarf.Entry) error

SeekToEntry moves the reader to an arbitrary entry.

func (*Reader) SeekToType

func (reader *Reader) SeekToType(entry *dwarf.Entry, resolveTypedefs bool, resolvePointerTypes bool) (*dwarf.Entry, error)

SeekToType moves the reader to the type specified by the entry, optionally resolving typedefs and pointer types. If the reader is set to a struct type the NextMemberVariable call can be used to walk all member data.

func (*Reader) SeekToTypeNamed

func (reader *Reader) SeekToTypeNamed(name string) (*dwarf.Entry, error)

SeekToTypeNamed moves the reader to the type specified by the name. If the reader is set to a struct type the NextMemberVariable call can be used to walk all member data.

type Variable

type Variable struct {
	*godwarf.Tree
	Depth int
}

func Variables

func Variables(root *godwarf.Tree, pc uint64, line int, onlyVisible, skipInlinedSubroutines bool) []Variable

Variables returns a list of variables contained inside 'root'. If onlyVisible is true only variables visible at pc will be returned. If skipInlinedSubroutines is true inlined subroutines will be skipped
