Still there with no arch/tune options.
Current mainline ("GNU C version 3.4 20030728 (experimental)") with "-O3
-fomit-frame-pointer -march=i686 -mtune=i686" produces:

foo:
        movl    4(%esp), %edx
        movl    8(%esp), %eax
        cmpl    %eax, %edx
        je      .L15
        cmpl    %eax, %edx
        cmovg   %edx, %eax
        ret
        .p2align 4,,7
.L15:
        addl    %eax, %eax
        ret
