Direct_Operand¶
- class Direct_Operand (abstract, logical)¶
Operand that does not involve a pointer indirection. Subclasses distinguish: read/write/address, or full object/subobject.
- Direct parents:
inherits Operand
- Ancestor classes and implemented interfaces:
- Direct child classes:
subclass Direct_Full_Operand
subclass Direct_Partial_Operand

Description
The_Object (from Operand)
semantic
interface General_Object_Interface
Affected object (direct case) or pointer (indirect case). For address operands, this can also be a routine. WARNING: because the meaning of this field is drastically different between direct operands and indirect operands, it is usually wrong to access this field without a preceding check of operand type!
Its_Type (from Operand)
semantic
class Type
The type of the operand. WARNING: For address operands, this field returns the pointed-to-type. That is, for
int i, the operand&iwill report Its_Type=int. Code using this field must check the read/write/address kind to avoid bugs!Parent (from Logical_IR_Root)
semantic
class Logical_IR_Root
Physical (from Logical_IR_Root)
semantic to physical
class Physical_IR_Root
