This is the most beneficial improvement, since the vertical pass involves a lot of cache trashing. With the bench_dwt utility with default arguments (16383x16383 image), time goes from 4.064 s to 1.212 s. Add bench_dwt program (compiled only if BUILD_BENCH_DWT=ON) 2017-06-20T15:56:19Z Even Rouault even.rouault@spatialys.com 2017-06-20T15:56:19Z urn:sha1:919ed5f8b8681aeae54ce3884b3ecca56cadc2e0 Remove OPJ_NOSANITIZE in opj_bio_read() and opj_bio_write() (#761) 2017-06-17T17:15:00Z Even Rouault even.rouault@spatialys.com 2017-06-17T17:15:00Z urn:sha1:8df2521a6015af7f69a378811986ddb0b3bfbd3a Commit 29313eb5 introduced those flags to avoid issues with -fsanitize=unsigned-integer-overflow However it is better just to rewrite the loop to avoid such condition to occur.
