The OperandOrigin object provides information about where an operand (function argument or return value) originates in the binary, including its source and definition addresses and positions.

​
Reference

​
source_address

The address where the operand’s value was sourced.

​
source_position

The position of the source IR instruction.

​
definition_address

The address where the operand was defined.

​
definition_position

The position of the IR instruction where the operand was defined.

​
index

The index of the operand in the context.

​
Example

-- Access the operand (OperandInfo) of the second argument
local src = context.inputs[2]

-- Access the origin information for the operand
local origin = src.origin

print("Source address:", origin.source_address)
print("Source position:", origin.source_position)
print("Definition address:", origin.definition_address)
print("Definition position:", origin.definition_position)
print("Operand index in context:", origin.index)
