Pointer_To_Member_Literal_Instruction

class Pointer_To_Member_Literal_Instruction (abstract, logical)

taking a member’s address without an object, as used for pointer-to-member literals:

char S::* p = &S::f;

class Composite_Type

Left (from Instruction)

syntactic

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 to NoNode.)

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):

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):
