Really squeezed lcd_write_data() with tricky assembler optimization. Now it does 114 fps when playing video from memory (way more than the ~75 fps needed, I need to slow down the video player), leaving headroom for audio. 2004-01-26T22:26:54+00:00 Jörg Hohensohn hohensoh@rockbox.org 2004-01-26T22:26:54+00:00 c546b70e18b7e0390c032e0fe0de15441cd7ed1b git-svn-id: svn://svn.rockbox.org/rockbox/trunk@4278 a1c6a512-1295-4272-9138-f99709370657

Now correctly informs gcc that r0 is clobbered in lcd_write_data().
