示例1: memcpy
SmallPtrSetImpl::SmallPtrSetImpl(const SmallPtrSetImpl& that) {
NumElements = that.NumElements;
NumTombstones = 0;
if (that.isSmall()) {
CurArraySize = that.CurArraySize;
CurArray = &SmallArray[0];
memcpy(CurArray, that.CurArray, sizeof(void*)*CurArraySize);
} else {
CurArraySize = that.NumElements < 64 ? 128 : that.NumElements*2;
CurArray = new void*[CurArraySize+1];
memset(CurArray, -1, CurArraySize*sizeof(void*));
// The end pointer, always valid, is set to a valid element to help the
// iterator.
CurArray[CurArraySize] = 0;
// Copy over all valid entries.
for (void **BucketPtr = that.CurArray, **E = that.CurArray+CurArraySize;
BucketPtr != E; ++BucketPtr) {
// Copy over the element if it is valid.
void *Elt = *BucketPtr;
if (Elt != getTombstoneMarker() && Elt != getEmptyMarker())
*const_cast<void**>(FindBucketFor(Elt)) = Elt;
}
}
}示例2: assert
SmallPtrSetImpl::SmallPtrSetImpl(const SmallPtrSetImpl& that) {
// If we're becoming small, prepare to insert into our stack space
if (that.isSmall()) {
CurArray = &SmallArray[0];
// Otherwise, allocate new heap space (unless we were the same size)
} else {
CurArray = (const void**)malloc(sizeof(void*) * (that.CurArraySize+1));
assert(CurArray && "Failed to allocate memory?");
}
// Copy over the new array size
CurArraySize = that.CurArraySize;
// Copy over the contents from the other set
memcpy(CurArray, that.CurArray, sizeof(void*)*(CurArraySize+1));
NumElements = that.NumElements;
NumTombstones = that.NumTombstones;
