SDL_GetCPUCacheLineSize(void) is used for getting CPU Cachelinesize. But the SDL_GetCPUCacheLineSize is only used in testplatfrom.c and testautomation_platform.c. I want know more about the usages of SDL_GetCPUCacheLineSize.
And i find the code about cacheline always use 128. If my cpu’s cacheline size is 64, does it will affect performance？
