Method AddBlocksToFunction

source/opt/loop_unroller.cpp:889–902

Whenever the utility copies a block it stores it in a temporary buffer, this function adds the buffer into the Function. The blocks will be inserted after the block |insert_point|.

// function adds the buffer into the Function. The blocks will be inserted
// after the block |insert_point|.
void LoopUnrollerUtilsImpl::AddBlocksToFunction(
    const BasicBlock* insert_point) {
  for (auto basic_block_iterator = function_.begin();
       basic_block_iterator != function_.end(); ++basic_block_iterator) {
    if (basic_block_iterator->id() == insert_point->id()) {
      basic_block_iterator.InsertBefore(&blocks_to_add_);
      return;
    }
  }

  assert(
      false &&
      "Could not add basic blocks to function as insert point was not found.");
}

// Assign all result_ids in |basic_block| instructions to new IDs and preserve
// the mapping of new ids to old ones.
