-// There are some assumptions for claiming memory(== making a reservation for memory).
-// 1. About _claim_table(std::map).
-//   - The table's data structure is std::map so that it always sorts
-//     value(model::operand::Index) by key(base_offset).
-//   - This claim() inserts key/value into _claim_table and the release() removes the key/value from
-//     _claim_table.
-//   - _claim_table shows the memory status at a certain point in time. Therefore,
-//     - If _claim_table has an offset and a certain size at a certain point in time,
-//       it means the place at the offset has been already claimed(== can't claim now. need to find
-//       someplace new).
-//     - If _claim_table doesn't have any element for an offset and a certain size at a certain
-//       point in time, it means the place at the offset can be claimed.
-// 2. In the loop for _claim_table, we can assume the current claim_base_offset value is bigger than
-//    the previous claim_base_offset.
