Public Attributes
FlowBlock *	exitproto
	Putative exit block for the BlockTrace.
BlockTrace *	trace
	The active BlockTrace being considered.
int4	distance
	Minimum distance crossed by this and any other BlockTrace sharing same exit block.
int4	terminal

int4	siblingedge
	Number of active BlockTraces with same BranchPoint and exit as this.

Detailed Description

Record for scoring a BlockTrace for suitability as an unstructured branch.

This class holds various metrics about BlockTraces that are used to sort them.

Member Function Documentation

compareFinal()

bool TraceDAG::BadEdgeScore::compareFinal

(

const BadEdgeScore &

op2

)

const

Compare BadEdgeScore for unstructured suitability.

Parameters

op2	is the other BadEdgeScore to compare with this

Returns

true if this is LESS likely to be the bad edge than op2

References TraceDAG::BranchPoint::depth, distance, siblingedge, terminal, TraceDAG::BlockTrace::top, and trace.

operator<()

bool TraceDAG::BadEdgeScore::operator<

(

const BadEdgeScore &

op2

)

const

Compare for grouping.

Comparator for grouping BlockTraces with the same exit block and parent BranchPoint

Parameters

op2	is the other BadEdgeScore to compare to

Returns

true is this should be ordered before op2
