* | Fixed off-by-one blending errors in the NEON drawhelper code. | Samuel Rødal | 2010-02-19 | 1 | -65/+65 |
| | | | | | | | | For example blending alpha 0xff with alpha 0xff and a 0.5 opacity gave a result of 0xfe instead of the correct 0xff. This caused some autotests to fail on ARM/NEON. Reviewed-by: TrustMe | ||||

* | NEON configure detection and initial blend function implementations. | Samuel Rødal | 2009-12-18 | 1 | -0/+260 |
Adds new NEON configure test and -no-neon configure option. NEON implementations can also be turned off by setting the QT_NO_NEON environment variable. Performance improvements (in frames per second): - Blending ARGB32 on RGB32/ARGB32, mostly opaque: 71 % - Blending ARGB32 on RGB32/ARGB32, no opaque pixels: 108 % - Blending ARGB32 on RGB32/ARGB32, with 0.5 opacity: 158 % - Blending RGB32 on RGB32/ARGB32, with 0.5 opacity: 189 % Task-number: QTBUG-6684 Reviewed-by: Gunnar Sletta Reviewed-by: Paul Olav Tvete |
