4 ORC unwinder
10 The kernel CONFIG_UNWINDER_ORC option enables the ORC unwinder, which is
11 similar in concept to a DWARF unwinder.  The difference is that the
13 the ORC unwinder to be much simpler and faster.
17 unwinder.  Objtool generates the ORC data by first doing compile-time
24 post-processed at boot time.  The unwinder uses the resulting data to
36 In contrast, the ORC unwinder has no effect on text size or runtime
38 frame pointers and enable the ORC unwinder, you get a nice performance
55 The main disadvantage of the ORC unwinder compared to frame pointers is
65 the tracking of unnecessary registers.  This allows the unwinder to be
69 The simpler debuginfo format also enables the unwinder to be much faster
71 performance test by Jiri Slaby [2]_, the ORC unwinder was about 20x
72 faster than an out-of-tree DWARF unwinder.  (Note: That measurement was
123 The downside is that the unwinder now becomes dependent on objtool's
163 enemies.  Similarly, the ORC unwinder was created in opposition to the
168 thought." [3]_  Similarly, unlike the esoteric DWARF unwinder, the
169 veracious ORC unwinder wastes no time or siloconic effort decoding
174 their adversaries, the ORC unwinder frequently unravels stacks with
