Thanks, that eliminated the spill to stack. The extra xmm1 to xmm0 move still
remains:

process:
.LFB0:
        .cfi_startproc
        movq    (%rdi), %rax
        cmpq    %rsi, %rdi
        movq    %rax, %rdx
        jae     .L2
        movq    (%rsi), %rdx
.L2:
        movd    %rdx, %xmm1
        pinsrq  $1, %rax, %xmm1
        movdqa  %xmm1, %xmm0
        ret
