* Revert r25929. Test have shown that the assembler code is more than 50% ↵Jens Arnold2010-05-10
| | | | | | faster than the C code both on ARM7TDMI (tested on PP5002 and PP5022) and on ARM1136JF-S (tested on Gigabeat S). If it is slower on ARM9*, it should be disabled for ARM9 only. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25937 a1c6a512-1295-4272-9138-f99709370657
