  Function abs
------------------------------------------------------------

Goal Post-condition (file tests/wp_plugin/abs.i, line 13) in 'abs':
Assume {
  (* Domain *)
  Type: (is_sint32 abs_0) /\ (is_sint32 x_0).
  (* tests/wp_plugin/abs.i:16: Conditional *)
  If: x_0<0
  Then { (* Control Flow *) Have: 0=(abs_0+x_0). }
  Else { (* Control Flow *) Have: abs_0=x_0. }
}
Prove: abs_0=(ABS x_0).
