I can't get the same code as you. With mainline gcc (gcc version 4.0.0 20041126
(experimental)) and 'gcc -O2 -S -fno-ivopts LU.c' I got:

        xorl    %edx, %edx
        .p2align 4,,15
.L5:
        leal    0(,%edx,8), %eax
        incl    %edx
        fldl    (%eax,%ecx)
        cmpl    %edx, %edi
        fstpl   (%ebx,%eax)
        jg      .L5

leal is redundant in this case.
