func BitVec(s *obj.LSym, off int, bv bitvec.BitVec) int
BitVec writes the contents of bv into s as sequence of bytes in little-endian order, and returns the next unused offset.
func Bool(s *obj.LSym, off int, v bool) int
func Global(s *obj.LSym, width int32, flags int16)
func LosesStmtMark(as obj.As) bool
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 SymPtr(s *obj.LSym, off int, x *obj.LSym, xoff int) int
func SymPtrOff(s *obj.LSym, off int, x *obj.LSym) int
func SymPtrWeak(s *obj.LSym, off int, x *obj.LSym, xoff int) int
func SymPtrWeakOff(s *obj.LSym, off int, x *obj.LSym) int
func Uint16(s *obj.LSym, off int, v uint16) int
func Uint32(s *obj.LSym, off int, v uint32) int
func Uint8(s *obj.LSym, off int, v uint8) int
Uint8 writes an unsigned byte v into s at offset off, and returns the next unused offset (i.e., off+1).
func UintN(s *obj.LSym, off int, v uint64, wid int) int
UintN writes an unsigned integer v of size wid bytes into s at offset off, and returns the next unused offset.
func Uintptr(s *obj.LSym, off int, v uint64) int
func Uvarint(s *obj.LSym, off int, v uint64) int
Uvarint writes a varint v into s at offset off, and returns the next unused offset.
Progs accumulates Progs for a function and converts them into machine code.
type Progs struct { Text *obj.Prog // ATEXT Prog for this function Next *obj.Prog // next Prog PC int64 // virtual PC; count of Progs Pos src.XPos // position to use for new Progs CurFunc *ir.Func // fn these Progs are for Cache []obj.Prog // local progcache CacheIndex int // first free element of progcache NextLive StackMapIndex // liveness index for the next Prog PrevLive StackMapIndex // last emitted liveness index NextUnsafe bool // unsafe mark for the next Prog PrevUnsafe bool // last emitted unsafe mark }
func NewProgs(fn *ir.Func, worker int) *Progs
NewProgs returns a new Progs for fn. worker indicates which of the backend workers will use the Progs.
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.Prog
func (pp *Progs) Clear(p *obj.Prog)
func (pp *Progs) Flush()
Flush converts from pp to machine code.
func (pp *Progs) Free()
Free clears pp and any associated resources.
func (pp *Progs) NewProg() *obj.Prog
func (pp *Progs) Prog(as obj.As) *obj.Prog
Prog adds a Prog with instruction As to pp.
func (pp *Progs) SetText(fn *ir.Func)
type StackMapIndex int
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).
const StackMapDontCare StackMapIndex = -1000
func (s StackMapIndex) StackMapValid() bool
