Relative cost-performance evolution of SPECint
static const uint32_t kMaskDelta = 0xa282ead8ul; // Return a masked representation of crc. // // Motivation: it is problematic to compute the CRC of a string that // contains embedded CRCs. Therefore we recommend that CRCs stored // somewhere (e.g., in files) should be masked before being stored. inline uint32_t Mask(uint32_t crc) { // Rotate right by 15 bits and add a constant. return ((crc >> 15) | (crc << 17)) + kMaskDelta; }
