示例1: while
LLVM_ATTRIBUTE_ALWAYS_INLINE
static const Metadata *findHashableBaseTypeImpl(const Metadata *type) {
// Check the cache first.
if (HashableConformanceEntry *entry =
HashableConformances->find(HashableConformanceKey{type})) {
return entry->baseTypeThatConformsToHashable;
}
if (!KnownToConformToHashable &&
!swift_conformsToProtocol(type, &_TMps8Hashable)) {
// Don't cache the negative response because we don't invalidate
// this cache when a new conformance is loaded dynamically.
return nullptr;
}
// By this point, `type` is known to conform to `Hashable`.
