Functions ¶
func BitVec ¶
BitVec writes the contents of bv into s as sequence of bytes in little-endian order, and returns the next unused offset.
func LosesStmtMark ¶
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 Uint8 ¶
Uint8 writes an unsigned byte v into s at offset off, and returns the next unused offset (i.e., off+1).
Types ¶
type Progs ¶
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
}
Progs accumulates Progs for a function and converts them into machine code.
func NewProgs ¶
NewProgs returns a new Progs for fn. worker indicates which of the backend workers will use the Progs.
type StackMapIndex ¶ added in go1.22.0
type StackMapIndex int
const StackMapDontCare StackMapIndex = -1000
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).
func (StackMapIndex) StackMapValid ¶ added in go1.22.0
func (s StackMapIndex) StackMapValid() bool
