[rguenth at gcc dot gnu dot org]

With MEM_REF I get on i686

foo:
        movl    a, %eax
        pushl   %ebp
        movl    %esp, %ebp
        popl    %ebp
        andl    $-33554240, %eax
        orl     $2074, %eax
        movl    %eax, a
        ret
        .size   foo, .-foo
        .p2align 4,,15
.globl bar
        .type   bar, @function
bar:
        movl    a, %eax
        pushl   %ebp
        movl    %esp, %ebp
        popl    %ebp
        andl    $192, %eax
        orl     $1048602, %eax
        movl    %eax, a
        ret

which shows that I made an error in the source ;)
