对于data段的描述存在疑惑

[Becavalier]

Hi, sorry for the delay. For example the following instructions stores an i32 “123” at byte range [4..7]:

i32.const 4    // byte-sized address
i32.const 123  // value to store
i32.store 2 0  // 2 = 32-bit/4-byte alignment, 0 = offset

The first immediate of the instruction "i32.store" is the alignment hint and the second immediate indicates the offset based on the base address you provide by operands (i32.const 4). So, the final address should be the base_addr + offset_addr.
