GetNextOpCodePositions()

Return the position of all instructions which can be reached from this one and if they should be part of the current group or not

Declaration
public virtual List<(bool newGroup, int Position)> GetNextOpCodePositions()
Returns
Type Description
System.Collections.Generic.List<System.ValueTuple<System.Boolean, System.Int32>>

GetNumberOfStackPops(MethodBase)

Returns the number of items popped from the stack. This is the logical stack, not physical items. So a 100byte struct is 1 pop, even though it might be multiple 32-bit or 64-bit words on the stack.

Declaration
public abstract int GetNumberOfStackPops(MethodBase aMethod)
Parameters
Type Name Description
System.Reflection.MethodBase aMethod
Returns
Type Description
System.Int32

Declaration
public abstract int GetNumberOfStackPushes(MethodBase aMethod)
Parameters
