Field	Kind	Type	Description
Condition	semantic	class Helper_Variable	The condition tested by this if block. This is guaranteed to be the value computed by the last instruction in this block.
Then_Next	semantic	class CFG_Block	The successor block when the condition (value computed by last instruction in this block) evaluates to non-zero.
Else_Next	semantic	class CFG_Block	The successor block when the condition (value computed by last instruction in this block) evaluates to zero.

Helpers (from CFG_Standard_Block)	syntactic	list of class Helper_Variable
Start_Role (from CFG_Standard_Block)	attribute	enum Cfg_Block_Start_Role	Provides an explanation why a new block was started. The Start_Physical edge provides details specific to the role. More details are documented on the individual role enumerators.
Start_Physical (from CFG_Standard_Block)	semantic to physical	class Physical_IR_Root	Physical edge related to the block start; see Start_Role for the interpretation of this edge.
