Summary: unaligned accesses in qt webkit

Details:

 

latest webkit in qt-4.4.3 does unaligned accesses which crashes on Blackfin

 

to reproduce, just build up qt-4.4.3 in latest trunk, enable the demos/examples, and then try to run the webkit examples in $STAGEDIR/usr/lib/examples/

 

you should get an unaligned crash

Fixed.

 

Add Macro QT_ARCH_BFIN to template qt_blend_argb24_on_rgb16() in

src/gui/painting/qblendfunctions.cpp to avoid data misaligned access.
