Default constructor

trace::TraceEvent::TraceEvent	(	ir::Dim3	t_blockId,
		ir::PTXU64	t_PC,
		const ir::PTXInstruction *	t_instruction,
		const boost::dynamic_bitset<> &	t_active,
		const U64Vector &	t_memory_addresses,
		ir::PTXU32	t_memory_size,
		ir::PTXU32	ctxStackSize = 1
	)

Constructs a trace event object

Parameters:

blockId	ID of block that generated the event
PC	index into EmulatedKernel's packed instruction sequence
instruction	const reference to instruction pointed to by PC
active	bit mask of active threads that executed this instruction
memory_addresses	vector of memory addresses possibly generated for this instruction
memory_sizes	vector of sizes of memory operations possibly issued by this instruction

Member Data Documentation

BitMask trace::TraceEvent::active

bit mask of active threads that executed this instruction

ir::Dim3 trace::TraceEvent::blockDim

dimensions of the kernel block that generated the event

ir::Dim3 trace::TraceEvent::blockId

ID of the block that generated the event

ir::PTXU32 trace::TraceEvent::contextStackSize

Depth of call stack [i.e. number of contexts on the runtime stack]

BitMask trace::TraceEvent::fallthrough

Fall through thread mask in case of a branch.

ir::Dim3 trace::TraceEvent::gridDim

dimensions of the kernel grid that generated the event

const ir::PTXInstruction* trace::TraceEvent::instruction

instruction const pointer to instruction pointed to by PC

U64Vector trace::TraceEvent::memory_addresses

vector of memory addresses possibly generated for this instruction - only contains actually accessed memory addresses, so the nth element in memory_addresses corresponds to the nth 1 in the active thread mask

ir::PTXU32 trace::TraceEvent::memory_size

vector of sizes of memory operations possibly issued by this instruction

ir::PTXU64 trace::TraceEvent::PC

PC index into EmulatedKernel's packed instruction sequence

ReconvergenceTraceEvent trace::TraceEvent::reconvergence

event capturing just events related to thread divergence and reconvergence

BitMask trace::TraceEvent::taken

Taken thread mask in case of a branch.
