Member Function Documentation

Emit()

template<class Backend , class EvtState >

std::size_t mc2lib::codegen::NullOp< Backend, EvtState >::Emit ( types::InstPtr  start, Backend *  backend, EvtState *  evts, void *  code, std::size_t  len  )

inlineoverridevirtual

Emit machine code.

Parameters

	start	Instruction pointer to first instruction when executing.
[in,out]	backend	Architecture backend.
[in,out]	evts	Pointer to EvtState instance of calling Compiler.
[out]	code	Pointer to memory to be copied into.
	len	Maximum lenth of code.

Returns

Size of emitted code.

Implements mc2lib::codegen::Op< Backend, EvtState >.

EnableEmit()

template<class Backend , class EvtState >

bool mc2lib::codegen::NullOp< Backend, EvtState >::EnableEmit ( EvtState *  evts )

inlineoverridevirtual

Prepares the operation for emit; common emit code.

Parameters

[in,out]

evts

Pointer to EvtState instance of calling Compiler.

Returns

true if can emit; false otherwise.

Implements mc2lib::codegen::Op< Backend, EvtState >.

FirstEvent()

template<class Backend , class EvtState >

const mc::Event* mc2lib::codegen::NullOp< Backend, EvtState >::FirstEvent ( const mc::Event *  prev_event, EvtState *  evts  ) const

inlineoverridevirtual

Accessor for first event generated.

Parameters

	prev_event	Event before first in program order; nullptr if none exists.
[in,out]	evts	Pointer to EvtState instance maintained by Compiler.

Returns

First event in program-order; nullptr if none exists.

Implements mc2lib::codegen::Op< Backend, EvtState >.

InsertPo()

template<class Backend , class EvtState >

void mc2lib::codegen::NullOp< Backend, EvtState >::InsertPo ( typename Op< Backend, EvtState >::ThreadConstIt  before, EvtState *  evts  )

inlineoverride

LastEvent()

template<class Backend , class EvtState >

const mc::Event* mc2lib::codegen::NullOp< Backend, EvtState >::LastEvent ( const mc::Event *  next_event, EvtState *  evts  ) const

inlineoverridevirtual

Accessor for last event generated. Also used to insert additional ordering based on passed next_event (e.g. fences).

Parameters

	next_event	Event after last in program order; nullptr if none exists.
[in,out]	evts	Pointer to EvtState instance maintained by Compiler.

Returns

Last event in program-order; nullptr if none exists.

Implements mc2lib::codegen::Op< Backend, EvtState >.

UpdateObs()

template<class Backend , class EvtState >

bool mc2lib::codegen::NullOp< Backend, EvtState >::UpdateObs ( types::InstPtr  ip, int  part, types::Addr  addr, const types::WriteID *  from_id, std::size_t  size, EvtState *  evts  )

inlineoverridevirtual

Updates dynamic observation for instruction's memory operation.

Parameters

	ip	Instruction pointer of instruction for which a value was observed.
	part	Which part of an instruction; e.g., if an instruction generates multiple memory events, part can be used to denote which.
	addr	Address for observed operation.
	from_id	Pointer to observed memory (WriteIDs).
	size	Total size of observed memory operations in from_id; implementation should assert expected size.
[in,out]	evts	Pointer to EvtState instance maintained by Compiler.

Returns

Success or not.
