12 * The fields of BASEOP are:
13 * op_next Pointer to next ppcode to execute after this one.
14 * (Top level pre-grafted op points to first op,
15 * but this is replaced when op is grafted in, when
16 * this op will point to the real next op, and the new
17 * parent takes over role of remembering starting op.)
18 * op_ppaddr Pointer to current ppcode's function.
19 * op_type The type of the operation.
2814eb74
PJ
20 * op_opt Whether or not the op has been optimised by the
21 * peephole optimiser.

DM
22 *
23 * See the comments in S_clear_yystack() for more
24 * details on the following three flags:
85594c31 25 *
670f3923
DM
26 * op_latefree tell op_free() to clear this op (and free any kids)
27 * but not yet deallocate the struct. This means that
28 * the op may be safely op_free()d multiple times
29 * op_latefreed an op_latefree op has been op_free()d
7e5d8ed2
DM
30 * op_attached this op (sub)tree has been attached to a CV
31 *
85594c31 32 * op_spare three spare bits!
79072805
LW
33 * op_flags Flags common to all operations. See OPf_* below.
34 * op_private Flags peculiar to a particular operation (BUT,
35 * by default, set to the number of children until
36 * the operation is privatized by a check routine,
37 * which may or may not check number of children).
