StackMapDontCare const #
StackMapDontCare indicates that the stack map index at a Value doesn't matter. This is a sentinel value that should never be emitted to the PCDATA stream. We use -1000 because that's obviously never a valid stack index (but -1 is).

Append method #
func (pp *Progs) Append(p *obj.Prog, as obj.As, ftype obj.AddrType, freg int16, foffset int64, ttype obj.AddrType, treg int16, toffset int64) *obj.ProgBitVec function #
BitVec writes the contents of bv into s as sequence of bytes in little-endian order, and returns the next unused offset.
func BitVec(s *obj.LSym, off int, bv bitvec.BitVec) intBool function #
func Bool(s *obj.LSym, off int, v bool) intClear method #
func (pp *Progs) Clear(p *obj.Prog)Flush method #
Flush converts from pp to machine code.
func (pp *Progs) Flush()Free method #
Free clears pp and any associated resources.
func (pp *Progs) Free()Global function #
func Global(s *obj.LSym, width int32, flags int16)LosesStmtMark function #
LosesStmtMark reports whether a prog with op as loses its statement mark on the way to DWARF. The attributes from some opcodes are lost in translation. TODO: this is an artifact of how funcpctab combines information for instructions at a single PC. Should try to fix it there.
func LosesStmtMark(as obj.As) boolNewProg method #
func (pp *Progs) NewProg() *obj.ProgNewProgs function #
NewProgs returns a new Progs for fn. worker indicates which of the backend workers will use the Progs.
func NewProgs(fn *ir.Func, worker int) *ProgsProg method #
Prog adds a Prog with instruction As to pp.
func (pp *Progs) Prog(as obj.As) *obj.ProgSetText method #
func (pp *Progs) SetText(fn *ir.Func)StackMapValid method #
func (s StackMapIndex) StackMapValid() boolSymPtr function #
func SymPtr(s *obj.LSym, off int, x *obj.LSym, xoff int) intSymPtrOff function #
func SymPtrOff(s *obj.LSym, off int, x *obj.LSym) intSymPtrWeak function #
func SymPtrWeak(s *obj.LSym, off int, x *obj.LSym, xoff int) intSymPtrWeakOff function #
func SymPtrWeakOff(s *obj.LSym, off int, x *obj.LSym) intUint16 function #
func Uint16(s *obj.LSym, off int, v uint16) intUint32 function #
func Uint32(s *obj.LSym, off int, v uint32) intUint8 function #
Uint8 writes an unsigned byte v into s at offset off, and returns the next unused offset (i.e., off+1).
func Uint8(s *obj.LSym, off int, v uint8) intUintN function #
UintN writes an unsigned integer v of size wid bytes into s at offset off, and returns the next unused offset.
func UintN(s *obj.LSym, off int, v uint64, wid int) intUintptr function #
func Uintptr(s *obj.LSym, off int, v uint64) intUvarint function #
Uvarint writes a varint v into s at offset off, and returns the next unused offset.
