* | Optimize pure C unscaled yuv2rgb.Reimar Döffinger2013-10-30
| | | | | | | | | | | | | | | | | | | | | | Aligning the tables reduces the amount of code generated on e.g. ARM as the offset constant then has few enough set bits so it can be encoded inside a single instruction instead of 2. Ideally all should be declared aligned, but the DECLARE_ALIGNED macros does not work with pointer tables, thus also reordered the tables. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
