Hi Guo Ren and C-SKY maintainers, Gentle ping on this patch.
My understanding is that r3 holds the original s1 pointer after r0 is cleared, so the alignment check should use r3 instead of r0. I also tested this on a CK860f chip, and the patched version was faster in my unaligned memcmp test. I may be missing some C-SKY ABIv2 detail, so any feedback would be appreciated. Thanks, Hanlin
