Consider the following function: + * + * void process_data(float *in, float *out, float gain, int nsamps) + * { + * int i; + * for (i = 0; i < nsamps; i++) { + * out[i] = in[i] * gain; + * } + * } + * + * In C or C++, it is legal for the parameters in and out to point to + * overlapping regions in memory. When this happens, in and out are said to be + * aliases. When the compiler optimizes the function, it does not in general + * know whether in and out are aliases. It must therefore assume that any + * store through out can affect the memory pointed to by in, which severely + * limits its ability to reorder or parallelize the code (For some simple + * cases, the compiler could analyze the entire program to determine that two + * pointers cannot be aliases. But in general, it is impossible for the + * compiler to determine whether or not two pointers are aliases, so to be + * safe, it must assume that they are). + */ |
