Inherited

from FlowGraphNode

bb

BasicBlock bb ( )
Java: getBB() · also: get_bb

build_data_flow_vars

build_data_flow_vars ( )

Get the control flow graph

compute_data_flow_info

compute_data_flow_info ( List<U> work_list, BitSet bb_set )
Java: computeDataFlowInfo(List<U> workList, BitSet bbSet)

compute_data_flow_info_backward

compute_data_flow_info_backward ( List<U> work_list, BitSet bb_set )
Java: computeDataFlowInfoBackward(List<U> workList, BitSet bbSet)

compute_data_flow_info_forward

compute_data_flow_info_forward ( List<U> work_list, BitSet bb_set )
Java: computeDataFlowInfoForward(List<U> workList, BitSet bbSet)

exception_target_node

U exception_target_node ( )
Java: getExceptionTargetNode() · also: get_exception_target_node

has_exceptions_rescued?

boolean has_exceptions_rescued? ( )
Java: hasExceptionsRescued() · also: has_exceptions_rescued
