Types ¶

type CallMap ¶

type CallMap struct {
	FuncMap
	CallSites []CallSite
}

CallMap implements compile.ObjectMapper. It stores all function addresses and call sites, but no instruction information.

func (*CallMap) FindAddr ¶ added in v0.8.0

func (m *CallMap) FindAddr(retAddr uint32) (funcIndex, _ uint32, stackOffset int32, initial, ok bool)

func (*CallMap) InitObjectMap ¶

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

func (*CallMap) PutCallSite ¶

func (m *CallMap) PutCallSite(retAddr uint32, stackOffset int32)

type CallSite ¶

type CallSite struct {
	RetAddr     uint32 // The address immediately after the call instruction
	StackOffset int32  // Calling function's stack usage at time of call
}

CallSite represents a position within the text section (machine code) where a function call is made.

type FuncMap ¶

type FuncMap struct {
	FuncAddrs []uint32
}

FuncMap implements compile.ObjectMapper. It stores all function addresses, but no call or instruction information.

func (*FuncMap) FindAddr ¶ added in v0.8.0

func (m *FuncMap) FindAddr(retAddr uint32) (funcIndex, _ uint32, _ int32, initial, ok bool)

func (*FuncMap) InitObjectMap ¶

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

func (*FuncMap) PutCallSite ¶

func (*FuncMap) PutCallSite(uint32, int32)

func (*FuncMap) PutDataBlock ¶ added in v0.8.0

func (*FuncMap) PutDataBlock(uint32, int32)

func (*FuncMap) PutFuncAddr ¶

func (m *FuncMap) PutFuncAddr(addr uint32)

func (*FuncMap) PutImportFuncAddr ¶

func (m *FuncMap) PutImportFuncAddr(addr uint32)

func (*FuncMap) PutInsnAddr ¶

func (*FuncMap) PutInsnAddr(uint32)
