Works OK for me with:

-O2 -m32 -march=i686 -msse2 -mfpmath=387

a:
        subl    $20, %esp
        fildl   24(%esp)
        cmpl    $10, 24(%esp)
        fstpl   (%esp)
        movq    (%esp), %xmm0
        movsd   (%esp), %xmm1
        movq    %xmm0, 8(%esp)
        movsd   %xmm1, b
        jg      .L1
        xorl    %eax, %eax
        movl    %eax, 12(%esp)
        movsd   8(%esp), %xmm2
        movsd   %xmm2, (%esp)
.L1:
        fldl    (%esp)
        addl    $20, %esp
        ret
