For band filter, source and destination are aligned (except for 16x16 ctbs), and otherwise, they are most often aligned. Overall, the total width is also too small for amortizing memcpy. Timings (using an intrinsic version of edge filters): B/32 B/64 E/32 E/64 Before: 32045 93952 38925 126896 After: 26772 83803 33942 117182

Usefull for at least band filter, for which: - Band filter call only: 32 64 Before: 16556 54015 After: 16497 52355 - Whole case: 32 64 Before: 37031 103008 After: 32045 93952

This is probably unneeded and normal int would be fine, but its safer to use LL and this isnt speed relevant Signed-off-by:

This uses explicit memory copying to read and write pointer to pointers of arbitrary object types. This works provided that the architecture uses the same representation for all pointer types (the previous code made that assumption already anyway). Signed-off-by:

Since the decoder has been fixed to output something similar to other implementations, the encoder weight table needed this fix. Reference PSNR values on a progressive sequence (from tiny_psnr) from a chained encoding and decoding: Full progressive: stddev: 0.74 PSNR: 50.69 MAXDIFF: 19 Before: stddev: 1.43 PSNR: 44.97 MAXDIFF: 17 This patch: stddev: 0.76 PSNR: 50.44 MAXDIFF: 14 Signed-off-by:
