Yes please file a new bug, the bug is that the register allocator sucks in GCC as of right now, with
-fnew-ra (an experimental register allocator) gives:
L11:
addi r2,r2,1
vaddfp v1,v11,v13
vaddfp v0,v12,v10
cmplw cr7,r2,r9
vmaddfp v11,v1,v11,v13
vmaddfp v12,v0,v12,v10
vsubfp v13,v1,v13
vsubfp v10,v0,v10
blt+ cr7,L11
