// A cacheline is the smallest unit with which locks are associated.
// The current implementation of the _ITM_[RW] barriers assumes that
// all data types can fit (aligned) within a cachline, which means
// in practice sizeof(complex long double) is the smallest cacheline size.
// It ought to be small enough for efficient manipulation of the
// modification mask, below.
