Hello,

the attached patch improves the performance of the rtl Move_blended procedure by about 16 % on ARMv4, when both destination and source addresses are aligned. I rearranged the code and could remove one instruction of the inner loop 'Ldwordloop'. I think the patch should work for the Move_pld procedure too (ARMv5), but I could not test it.

Regards, Bernd.
