Here is the latest asm from the mainline:
mul:
        subl    $20, %esp
        movl    32(%esp), %ecx
        movl    24(%esp), %eax
        movl    %ebx, 8(%esp)
        movl    36(%esp), %ebx
        movl    %edi, 12(%esp)
        movl    24(%esp), %edi
        movl    %ebp, 16(%esp)
        mull    %ecx
        imull   28(%esp), %ecx
        imull   %ebx, %edi
        movl    8(%esp), %ebx
        movl    %edx, %ebp
        movl    %eax, (%esp)
        addl    %edi, %ebp
