x86: hevc_mc: split differently calls
In some cases, 2 or 3 calls are performed to functions for unusual widths. Instead, perform 2 calls for different widths to split the workload. The 8+16 and 4+8 widths for respectively 8 and more than 8 bits can't be processed that way without modifications: some calls use unaligned buffers, and having branches to handle this was resulting in no micro-benchmark benefit. For block_w == 12 (around 1% of the pixels of the sequence): Before: 12758 decicycles in epel_uni, 4093 runs, 3 skips 19389 decicycles in qpel_uni, 8187 runs, 5 skips 22699 decicycles in epel_bi, 32743 runs, 25 skips 34736 decicycles in qpel_bi, 32733 runs, 35 skips After: 11929 decicycles in epel_uni, 4096 runs, 0 skips 18131 decicycles in qpel_uni, 8184 runs, 8 skips 20065 decicycles in epel_bi, 32750 runs, 18 skips 31458 decicycles in qpel_bi, 32753 runs, 15 skips Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
