Well this is interesting:
<after PRE of the expression>
(gdb) p debug_generic_stmt (bb_ann (basic_block_info.data.bb[8157])->phi_nodes)
#   pretmp.1992_99947 = PHI <T.140_39112(8071), T.140_39231(8085)>;
pretmp.1992_99947 = PHI <T.140_39112(8071), T.140_39231(8085)>;

<after PRE is done>

(gdb) p debug_generic_stmt (bb_ann (basic_block_info.data.bb[8157])->phi_nodes)
 EUSE () [class:-1 phiop:1 bb:236 ]
