    XMLWordPrintableJSON

    Description

      Hello,

      For setting a bit in bit map (which is used in gandiva) we have a branch statement which can be replaced by bit operations like this

      bmap[byteIdx] ^= (-value ^ bmap[byteIdx]) & (1UL << bitIdx);
      

       which performs the same operation and we have avoid the branching.
