Description
For the !bi case, when the pixel value, PROF delta, and fixed offset are all added together, prior to the shift, the end result can overflow the 16-bit data type. The specific line from applyPROF_SSE is as follows:
mm_dI = _mm256_srai_epi16(_mm256_add_epi16(mm_dI, mm_offset), shiftNum);
