Variable Documentation

ImpossibleRepairCost

unsigned ImpossibleRepairCost

staticconstexpr

Initial value:

=
    std::numeric_limits<unsigned>::max()

Cost value representing an impossible or invalid repairing.

This matches the value returned by RegisterBankInfo::copyCost() and RegisterBankInfo::getBreakDownCost() when the cost cannot be computed.
