虽然指令集主要是将它们拆解成4个32位的字,不过对于这种情况的处理已经有足够的支持了。
The instruction set is primarily geared around dividing it into four 32-bit words, but there is enough support to handle any of these situations.
记住,lqd指令只能从16字节边界加载,所以它会在加载期间忽略最低有效的四位,而只会从内存加载已对齐的四字。
Remember, the LQD instruction only loads from 16-byte boundaries. It will therefore ignore the four least significant bits during the load, and just load an aligned quadword from memory.
bytecode 一词从这样的实现演变而来,即出于简便和性能考虑将其虚拟机指令集有效实现为单一字节。
The term bytecode evolved from implementations that efficiently implemented their virtual instruction sets as single bytes for simplicity and performance.
