OperandOrigin

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.

Fields

Field	Description	Type
source_address	Address where the operand’s value was sourced	AddressValue
source_position	Position of the source IR instruction	number
definition_address	Address where the operand was defined	AddressValue
definition_position	Position of the IR instruction where the operand was defined	number
index	Index of the operand in the context	number

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)
