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 |
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. |
670f3923 |
25 | * op_latefree tell op_free() to clear this op (and free any kids) |
26 | * but not yet deallocate the struct. This means that |
27 | * the op may be safely op_free()d multiple times |
28 | * op_latefreed an op_latefree op has been op_free()d |
29 | * op_spare three spare bits! |
79072805 |
30 | * op_flags Flags common to all operations. See OPf_* below. |
31 | * op_private Flags peculiar to a particular operation (BUT, |
32 | * by default, set to the number of children until |
33 | * the operation is privatized by a check routine, |
34 | * which may or may not check number of children). |
