type InsnMap ¶

type InsnMap struct {
	object.CallMap
	Insns []InsnMapping
	// contains filtered or unexported fields
}

InsnMap implements compile.ObjectMapper. It stores function addresses, call sites and instruction positions.

The WebAssembly module must be loaded using InsnMap's pass-through reader, or the source positions will be zero.

func (m *InsnMap) FindAddr(retAddr uint32) (funcIndex, callIndex, retInsnPos uint32, stackOffset int32, initial, ok bool)

func (m *InsnMap) InitObjectMap(numImportFuncs, numOtherFuncs int)

func (m *InsnMap) PutDataBlock(objectPos uint32, blockLen int32)

func (m *InsnMap) PutInsnAddr(objectPos uint32)

func (m *InsnMap) Reader(input reader.R) reader.R

type InsnMapping ¶

type InsnMapping struct {
	ObjectPos uint32 // Machine code offset in bytes.
	SourcePos uint32 // WebAssembly code offset in bytes.
	BlockLen  int32  // Length of data block (when SourcePos is 0).
}

Instruction mapping from machine code to WebAssembly. SourcePos is zero if ObjectPos contains non-executable data interleaved with the code.
