This instruction is used to load a vector from memory into a vector register. The **LVX** instructions on ppc64 require 16 byte alignment of the data. To avoid that requirement, data is loaded using **LXVD2X** with **VPERM** to reorder bytes correctly. -- **LXVDSX** "Load Vector Doubleword Scalar Indexed". This instruction is used to load a doubleword (64-bit element) from memory into a vector register.从指定内存位置加载64位数据,将其存储到目标向量寄存器的lower half(byte index from 0-7)。 +- **LXVDSX** "Load VSR Vector Doubleword and Splat Indexed". This instruction is used to load a doubleword (64-bit element) from memory into a vector register.从指定内存位置加载64位数据,将其存储到目标向量寄存器的lower half(byte index from 0-7), 并将相同值复制到higher half (byte index from 8-16)。 - **LVXD2X** "Load Vector Doubleword 2 Indexed". This instruction is used to load two consecutive doublewords (64-bit elements) from memory into a vector register. 加载两个连续的64位数到目标向量寄存器。 - **LXVW4X** "Load Vector Word Indexed". It loads a vector of 4 words (16 bytes total, as each word is 4 bytes) from memory into a vector register.
