------- Comment #7 from steven at gcc dot gnu dot org  2006-02-11 00:52 -------
"GCC: (GNU) 4.2.0 20060210 (experimental)" produces this
(at "-O2 -march=pentium4"):

foo:
        movl    a, %eax
        addl    $1, %eax
        movl    %eax, a
        testl   %eax, %eax
        je      .L4
        addl    $1, %eax
        movl    %eax, a
.L4:
        ret
