Left (from Instruction)

class Operand
Where the result will be stored. This is always a write operand. (can be NULL, e.g., for calls to void funcs or assertion instructions. Check cafe’s
can_omit_lhs()for the full list of instructions that can have Left equal toNoNode.)Left_Physical (from Instruction)
semantic to physical
class Physical_IR_Root
This edge instead points to the expression that represents the left operand, i.e., the expression that computed the glvalue where the result of the instruction will be stored.
For example, in
v = 42;(a LIR Integer_Literal_Instruction):The
Physicaledge points to the PIR Integer_Literal.The
Left_Physicaledge points to the Unqualified_Direct_Object_Selection for the variablev.And the
Physical_For_Assignmentedge points to the Assignment expression.
Its_Type (from Instruction)
semantic
class Type
Result type of the instruction, needed especially to distinguish assignments of complete structs from assignments of their first fields. Also needed to determine multiplication factor for pointer additions. For Cast_Instructions, this is the type casted to
Physical_For_Assignment (from Instruction)
semantic to physical
class Physical_IR_Root
Returns a PIR node for the assignment of the value that was computed by this instruction.
For example, in
v = 42;(a LIR Integer_Literal_Instruction):The
Physicaledge points to the PIR Integer_Literal.The
Left_Physicaledge points to the Unqualified_Direct_Object_Selection for the variablev.And the
Physical_For_Assignmentedge points to the Assignment expression.
