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.
22 * op_static Whether or not the op is statically defined.
23 * This flag is used by the B::C compiler backend
24 * and indicates that the op should not be freed.
25 * op_spare Five spare bits!
79072805
LW
26 * op_flags Flags common to all operations. See OPf_* below.
27 * op_private Flags peculiar to a particular operation (BUT,
28 * by default, set to the number of children until
29 * the operation is privatized by a check routine,
30 * which may or may not check number of children).
