Description
It seems like merge request 1040 (JVET-P0091: Align sample offset calculation of BDOF and PROF) introduced significant drop in coding performance for RA configuration. Using the following compilation environment the drop in performance seems to be in the 3-5 % range:
[Linux][GCC 8.2.1][64 bit] [SIMD=AVX2]

- Resolution set to fixed
- Status changed from new to closed
Note: See TracTickets for help on using tickets.
"sum = _mm_add_epi32(sum, a);" is missed in the SIMD implementation. A fix will be provided in a new merge request.
