示例1: VectorizedIterate
// Iterate over the tuples in the sorter in batches/vectors of the given size
void Sorter::VectorizedIterate(
CodeGen &codegen, llvm::Value *sorter_ptr, uint32_t vector_size,
uint64_t offset, Sorter::VectorizedIterateCallback &callback) const {
llvm::Value *start_pos = codegen.Load(SorterProxy::tuples_start, sorter_ptr);
llvm::Value *num_tuples = NumTuples(codegen, sorter_ptr);

if (offset != 0) {
start_pos = codegen->CreateConstInBoundsGEP1_32(codegen.CharPtrType(),
start_pos, offset);
num_tuples = codegen->CreateSub(num_tuples, codegen.Const32(offset));
}
lang::VectorizedLoop loop(codegen, num_tuples, vector_size, {});
{
// Current loop range
auto curr_range = loop.GetCurrentRange();
// Provide an accessor into the sorted space
SorterAccess sorter_access(*this, start_pos);
// Issue the callback
callback.ProcessEntries(codegen, curr_range.start, curr_range.end,
sorter_access);
// That's it
loop.LoopEnd(codegen, {});
