Note that the mptr, not this slot, is grained on an 8 byte boundary. The flags are as follows
请注意，mptr 是按 8 字节边界划分颗粒度的，而这一位置不是。
The pre-requisite to deploy TXSeries applications as a Web services is to compile them with 8 byte boundary.

To load a value which crosses a 16-byte boundary is even more difficult, as you would actually have to load it into two registers, shift them, and then mask and combine them.
要加载跨越 16 字节边界的值会十分困难，因为必须要将其存储到两个寄存器，进行移位然后再对它们进行掩码和组合。
