        CommonType
        BitSize   int64
        BitOffset int64
}

type BoolType struct {
        BasicType
}

type CharType

A CharType represents a signed character type.

type CharType struct {
        BasicType
}

type Class

A Class is the DWARF 4 class of an attribute value.

In general, a given attribute's value may take on one of several possible classes defined by DWARF, each of which leads to a slightly different interpretation of the attribute.

DWARF version 4 distinguishes attribute value classes more finely than previous versions of DWARF. The reader will disambiguate coarser classes from earlier versions of DWARF into the appropriate DWARF 4 class. For example, DWARF 2 uses "constant" for constants as well as all types of section offsets, but the reader will canonicalize attributes in DWARF 2 files that refer to section offsets to one of the Class*Ptr classes, even though these classes were only defined in DWARF 3.

type Class int
const (
        // ClassUnknown represents values of unknown DWARF class.
        ClassUnknown Class = iota

        // ClassAddress represents values of type uint64 that are
        // addresses on the target machine.
        ClassAddress

        // ClassBlock represents values of type []byte whose
        // interpretation depends on the attribute.
        ClassBlock

        // ClassConstant represents values of type int64 that are
        // constants. The interpretation of this constant depends on
        // the attribute.
        ClassConstant

        // ClassExprLoc represents values of type []byte that contain
        // an encoded DWARF expression or location description.
        ClassExprLoc

        // ClassFlag represents values of type bool.
        ClassFlag

        // ClassLinePtr represents values that are an int64 offset
        // into the "line" section.
        ClassLinePtr

        // ClassLocListPtr represents values that are an int64 offset
        // into the "loclist" section.
        ClassLocListPtr

        // ClassMacPtr represents values that are an int64 offset into
        // the "mac" section.
        ClassMacPtr

        // ClassMacPtr represents values that are an int64 offset into
        // the "rangelist" section.
        ClassRangeListPtr

        // ClassReference represents values that are an Offset offset
        // of an Entry in the info section (for use with Reader.Seek).
        // The DWARF specification combines ClassReference and
        // ClassReferenceSig into class "reference".
        ClassReference

        // ClassReferenceSig represents values that are a uint64 type
        // signature referencing a type Entry.
        ClassReferenceSig

        // ClassString represents values that are strings. If the
        // compilation unit specifies the AttrUseUTF8 flag (strongly
        // recommended), the string value will be encoded in UTF-8.
        // Otherwise, the encoding is unspecified.
        ClassString

        // ClassReferenceAlt represents values of type int64 that are
        // an offset into the DWARF "info" section of an alternate
        // object file.
        ClassReferenceAlt

        // ClassStringAlt represents values of type int64 that are an
        // offset into the DWARF string section of an alternate object
        // file.
        ClassStringAlt
)

type CommonType

A CommonType holds fields common to multiple types. If a field is not known or not applicable for a given type, the zero value is used.

type CommonType struct {
        ByteSize int64  // size of value of this type, in bytes
        Name     string // name that can be used to refer to type
}

func (*CommonType) Common

func (c *CommonType) Common() *CommonType

func (*CommonType) Size

func (c *CommonType) Size() int64

type ComplexType

A ComplexType represents a complex floating point type.

type ComplexType struct {
        BasicType
}

type Data

Data represents the DWARF debugging information loaded from an executable file (for example, an ELF or Mach-O executable).

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

func New

func New(abbrev, aranges, frame, info, line, pubnames, ranges, str []byte) (*Data, error)

New returns a new Data object initialized from the given parameters. Rather than calling this function directly, clients should typically use the DWARF method of the File type of the appropriate package debug/elf, debug/macho, or debug/pe.

The []byte arguments are the data from the corresponding debug section in the object file; for example, for an ELF object, abbrev is the contents of the ".debug_abbrev" section.

func (*Data) AddTypes

func (d *Data) AddTypes(name string, types []byte) error

AddTypes will add one .debug_types section to the DWARF data. A typical object with DWARF version 4 debug info will have multiple .debug_types sections. The name is used for error reporting only, and serves to distinguish one .debug_types section from another.

func (*Data) LineReader

func (d *Data) LineReader(cu *Entry) (*LineReader, error)

LineReader returns a new reader for the line table of compilation unit cu, which must be an Entry with tag TagCompileUnit.

If this compilation unit has no line table, it returns nil, nil.

func (*Data) Ranges

func (d *Data) Ranges(e *Entry) ([][2]uint64, error)

Ranges returns the PC ranges covered by e, a slice of [low,high) pairs. Only some entry types, such as TagCompileUnit or TagSubprogram, have PC ranges; for others, this will return nil with no error.

func (*Data) Reader

func (d *Data) Reader() *Reader

Reader returns a new Reader for Data. The reader is positioned at byte offset 0 in the DWARF “info” section.

func (*Data) Type

func (d *Data) Type(off Offset) (Type, error)

Type reads the type at off in the DWARF “info” section.

type DecodeError

type DecodeError struct {
        Name   string
        Offset Offset
        Err    string
}

func (DecodeError) Error

func (e DecodeError) Error() string

type DotDotDotType

A DotDotDotType represents the variadic ... function parameter.

type DotDotDotType struct {
        CommonType
}

func (*DotDotDotType) String

func (t *DotDotDotType) String() string

type Entry

An entry is a sequence of attribute/value pairs.

type Entry struct {
        Offset   Offset // offset of Entry in DWARF info
        Tag      Tag    // tag (kind of Entry)
        Children bool   // whether Entry is followed by children
        Field    []Field
}

func (*Entry) AttrField

func (e *Entry) AttrField(a Attr) *Field

AttrField returns the Field associated with attribute Attr in Entry, or nil if there is no such attribute.

func (*Entry) Val

func (e *Entry) Val(a Attr) interface{}

Val returns the value associated with attribute Attr in Entry, or nil if there is no such attribute.

A common idiom is to merge the check for nil return with the check that the value has the expected dynamic type, as in:

v, ok := e.Val(AttrSibling).(int64)

type EnumType

An EnumType represents an enumerated type. The only indication of its native integer type is its ByteSize (inside CommonType).

type EnumType struct {
        CommonType
        EnumName string
        Val      []*EnumValue
}

func (*EnumType) String

func (t *EnumType) String() string

type EnumValue

An EnumValue represents a single enumeration value.

type EnumValue struct {
        Name string
        Val  int64
}

type Field

A Field is a single attribute/value pair in an Entry.

A value can be one of several "attribute classes" defined by DWARF. The Go types corresponding to each class are:

DWARF class       Go type        Class
-----------       -------        -----
address           uint64         ClassAddress
block             []byte         ClassBlock
constant          int64          ClassConstant
flag              bool           ClassFlag
reference
  to info         dwarf.Offset   ClassReference
  to type unit    uint64         ClassReferenceSig
string            string         ClassString
exprloc           []byte         ClassExprLoc
lineptr           int64          ClassLinePtr
loclistptr        int64          ClassLocListPtr
macptr            int64          ClassMacPtr
rangelistptr      int64          ClassRangeListPtr

For unrecognized or vendor-defined attributes, Class may be ClassUnknown.

type LineEntry struct {
        // Address is the program-counter value of a machine
        // instruction generated by the compiler. This LineEntry
        // applies to each instruction from Address to just before the
        // Address of the next LineEntry.
        Address uint64

        // OpIndex is the index of an operation within a VLIW
        // instruction. The index of the first operation is 0. For
        // non-VLIW architectures, it will always be 0. Address and
        // OpIndex together form an operation pointer that can
        // reference any individual operation within the instruction
        // stream.
        OpIndex int

        // File is the source file corresponding to these
        // instructions.
        File *LineFile

        // Line is the source code line number corresponding to these
        // instructions. Lines are numbered beginning at 1. It may be
        // 0 if these instructions cannot be attributed to any source
        // line.
        Line int

        // Column is the column number within the source line of these
        // instructions. Columns are numbered beginning at 1. It may
        // be 0 to indicate the "left edge" of the line.
        Column int

        // IsStmt indicates that Address is a recommended breakpoint
        // location, such as the beginning of a line, statement, or a
        // distinct subpart of a statement.
        IsStmt bool

        // BasicBlock indicates that Address is the beginning of a
        // basic block.
        BasicBlock bool

        // PrologueEnd indicates that Address is one (of possibly
        // many) PCs where execution should be suspended for a
        // breakpoint on entry to the containing function.
        //
        // Added in DWARF 3.
        PrologueEnd bool

        // EpilogueBegin indicates that Address is one (of possibly
        // many) PCs where execution should be suspended for a
        // breakpoint on exit from this function.
        //
        // Added in DWARF 3.
        EpilogueBegin bool

        // ISA is the instruction set architecture for these
        // instructions. Possible ISA values should be defined by the
        // applicable ABI specification.
        //
        // Added in DWARF 3.
        ISA int

        // Discriminator is an arbitrary integer indicating the block
        // to which these instructions belong. It serves to
        // distinguish among multiple blocks that may all have with
        // the same source file, line, and column. Where only one
        // block exists for a given source position, it should be 0.
        //
        // Added in DWARF 3.
        Discriminator int

        // EndSequence indicates that Address is the first byte after
        // the end of a sequence of target machine instructions. If it
        // is set, only this and the Address field are meaningful. A
        // line number table may contain information for multiple
        // potentially disjoint instruction sequences. The last entry
        // in a line table should always have EndSequence set.
        EndSequence bool
}

type LineFile

A LineFile is a source file referenced by a DWARF line table entry.

type LineFile struct {
        Name   string
        Mtime  uint64 // Implementation defined modification time, or 0 if unknown
        Length int    // File length, or 0 if unknown
}

type LineReader

A LineReader reads a sequence of LineEntry structures from a DWARF "line" section for a single compilation unit. LineEntries occur in order of increasing PC and each LineEntry gives metadata for the instructions from that LineEntry's PC to just before the next LineEntry's PC. The last entry will have its EndSequence field set.

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

func (*LineReader) Next

func (r *LineReader) Next(entry *LineEntry) error

Next sets *entry to the next row in this line table and moves to the next row. If there are no more entries and the line table is properly terminated, it returns io.EOF.

Rows are always in order of increasing entry.Address, but entry.Line may go forward or backward.

func (*LineReader) Reset

func (r *LineReader) Reset()

Reset repositions the line table reader at the beginning of the line table.

func (*LineReader) Seek

func (r *LineReader) Seek(pos LineReaderPos)

Seek restores the line table reader to a position returned by Tell.

The argument pos must have been returned by a call to Tell on this line table.

func (*LineReader) SeekPC

func (r *LineReader) SeekPC(pc uint64, entry *LineEntry) error

SeekPC sets *entry to the LineEntry that includes pc and positions the reader on the next entry in the line table. If necessary, this will seek backwards to find pc.

If pc is not covered by any entry in this line table, SeekPC returns ErrUnknownPC. In this case, *entry and the final seek position are unspecified.

Note that DWARF line tables only permit sequential, forward scans. Hence, in the worst case, this takes time linear in the size of the line table. If the caller wishes to do repeated fast PC lookups, it should build an appropriate index of the line table.

func (*LineReader) Tell

func (r *LineReader) Tell() LineReaderPos

Tell returns the current position in the line table.

type LineReaderPos

A LineReaderPos represents a position in a line table.

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

type Offset

An Offset represents the location of an Entry within the DWARF info. (See Reader.Seek.)

type Offset uint32

type PtrType

A PtrType represents a pointer type.

type PtrType struct {
        CommonType
        Type Type
}

func (*PtrType) String

func (t *PtrType) String() string

type QualType

A QualType represents a type that has the C/C++ "const", "restrict", or "volatile" qualifier.

type QualType struct {
        CommonType
        Qual string
        Type Type
}

func (*QualType) Size

func (t *QualType) Size() int64

func (*QualType) String

func (t *QualType) String() string

type Reader

A Reader allows reading Entry structures from a DWARF “info” section. The Entry structures are arranged in a tree. The Reader's Next function return successive entries from a pre-order traversal of the tree. If an entry has children, its Children field will be true, and the children follow, terminated by an Entry with Tag 0.

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

func (*Reader) AddressSize

func (r *Reader) AddressSize() int

AddressSize returns the size in bytes of addresses in the current compilation unit.

func (*Reader) Next

func (r *Reader) Next() (*Entry, error)

Next reads the next entry from the encoded entry stream. It returns nil, nil when it reaches the end of the section. It returns an error if the current offset is invalid or the data at the offset cannot be decoded as a valid Entry.

func (*Reader) Seek

func (r *Reader) Seek(off Offset)

Seek positions the Reader at offset off in the encoded entry stream. Offset 0 can be used to denote the first entry.

func (*Reader) SeekPC

func (r *Reader) SeekPC(pc uint64) (*Entry, error)

SeekPC returns the Entry for the compilation unit that includes pc, and positions the reader to read the children of that unit. If pc is not covered by any unit, SeekPC returns ErrUnknownPC and the position of the reader is undefined.

Because compilation units can describe multiple regions of the executable, in the worst case SeekPC must search through all the ranges in all the compilation units. Each call to SeekPC starts the search at the compilation unit of the last call, so in general looking up a series of PCs will be faster if they are sorted. If the caller wishes to do repeated fast PC lookups, it should build an appropriate index using the Ranges method.

func (*Reader) SkipChildren

func (r *Reader) SkipChildren()

SkipChildren skips over the child entries associated with the last Entry returned by Next. If that Entry did not have children or Next has not been called, SkipChildren is a no-op.

type StructField

A StructField represents a field in a struct, union, or C++ class type.

type StructField struct {
        Name       string
        Type       Type
        ByteOffset int64
        ByteSize   int64 // usually zero; use Type.Size() for normal fields
        BitOffset  int64 // within the ByteSize bytes at ByteOffset
        BitSize    int64 // zero if not a bit field
}

type StructType

A StructType represents a struct, union, or C++ class type.

type StructType struct {
        CommonType
        StructName string
        Kind       string // "struct", "union", or "class".
        Field      []*StructField
        Incomplete bool // if true, struct, union, class is declared but not defined
}

func (*StructType) Defn

func (t *StructType) Defn() string

func (*StructType) String

func (t *StructType) String() string
