--- Comment #7 from amker at gcc dot gnu.org ---
We are almost there. The generated assembly for both attached and extracted
case is like:
.L16:
movl -4(%r12,%rdx,4), %edi
movl (%rsi,%rax,4), %r11d
movl %r11d, -4(%r12,%rdx,4)
movl %edi, (%rsi,%rax,4)
movl %edx, %r11d
movl %eax, %edi
addq $1, %rdx
subq $1, %rax
cmpl %edi, %r11d
jl .L16
