C++ (Cpp) __rev Examples

Example #1

File: stm32f4xx_crc.c Project: Tarintote/icub-firmware

/**
  * @brief  Computes the 32-bit CRC of a given buffer of data word(32-bit).
  * @param  pBuffer: pointer to the buffer containing the data to be computed
  * @param  BufferLength: length of the buffer to be computed					
  * @retval 32-bit CRC
  */
uint32_t CRC_CalcBlockCRC_networkorder(uint32_t pBuffer[], uint32_t BufferLength)
{
  uint32_t index = 0;

//#warning --> acemor says: the standard crc32 works on bytes with network order but the stm32 hw uses little endian mode

  for(index = 0; index < BufferLength; index++)
  {
    CRC->DR = __rev(pBuffer[index]);  //IIT: the standard crc32 works on network order but the stm32 hw works on little endian mode
  }
  return (CRC->DR);
}

Example #2

File: arm_acle.c Project: cms-externals/clang

// ARM-LABEL: test_rev
// ARM: call i32 @llvm.bswap.i32(i32 %t)
uint32_t test_rev(uint32_t t) {
  return __rev(t);
}
