This patch set consists in :
Results on the performance test suite (ref time is current master):
On (private image) MAPA.jp2 (recoded with standard flags), decoding time goes from 50.168 s to 45.030, so a reduction by 10% of decoding time as wel.
…#172) Ported from Carl Hetherington work (actually through Matthieu Darbois's port on top of OpenJPEG 2.1.0) Can reduce total encoding time by 10-15% WARNING: VSC mode is not implemented, and so is a temporary regression that must be fixed.
…cros, so as to get better register allocation
…th row. Do not set them when updating flags of the 1st row
This saves comparing the current pointer with the end of buffer pointer. This results at least in tiny speed improvement for raw decoding, and smaller code size for MQC as well. This kills the remains of the raw.h/.c files that were only used for decoding. Encoding using the mqc structure already.
