class MachineInstr::ExtraInfo

Declaration

class MachineInstr::ExtraInfo : private TrailingObjects { /* full declaration omitted */ };

Description

Internal implementation detail class that provides out-of-line storage for extra info used by the machine instruction when this info cannot be stored in-line within the instruction itself. This has to be defined eagerly due to the implementation constraints of `PointerSumType` where it is used.
