摘要： A target operation in a normalized target loop, susceptible of vectorization and which may, after compilation into a vectorized form, seek to operate on data in nonconsecutive physical memory, is identified in source code. Hardware instructions are inserted into executable code generated from the source code, directing a system that will run the executable code to create a representation of the data in consecutive physical memory. A vector loop containing the target operation is replaced, in the executable code, with a function call to a vector library to call a vector function that will operate on the representation to generate a result identical to output expected from executing the vector loop containing the target operation. On execution, a representation of data residing in nonconsecutive physical memory is created in consecutive physical memory, and the vectorized target operation is applied to the representation to process the data.

摘要翻译： 标准化目标循环中的目标操作，易于向量化，并且可以在编译成向量化形式之后寻求对非连续物理存储器中的数据进行操作，在源代码中被识别。 硬件指令被插入到从源代码生成的可执行代码中，指示将运行可执行代码的系统在连续的物理内存中创建数据的表示。 包含目标操作的向量循环在可执行代码中被替换为对向量库的函数调用，以调用将在表示上操作的向量函数，以生成与执行包含目标的向量循环所期望的输出相同的结果 操作。 在执行时，在连续物理存储器中创建驻留在非连续物理存储器中的数据的表示，并且向量化的目标操作被应用于表示以处理数据。
