So specifying a -m128bit-long-double will align "long double" to a 16-byte boundary by padding the "long double" with an additional 32-bit zero.

因此指定一个- m 128bit - long - double会将“long double”按照16字节边界进行对齐，它会为“long double”填充32位的0。

A zero-padding algorithm based on correlation-based image analysis theory with the accuracy of sub-pixel class was presented to determine the benchmarks in different digital images.

基于图像相关分析理论提出了一种新的补零相关分析算法以确定不同数字图像上的相关标记点，其测量精度可达亚像素量级。
