24 | /* The numbering of these signals is chosen to match traditional unix | |
25 | signals (insofar as various unices use the same numbers, anyway). | |
26 | It is also the numbering of the GDB remote protocol. Other remote | |
27 | protocols, if they use a different numbering, should make sure to | |
28 | translate appropriately. | |
29 | ||
30 | Since these numbers have actually made it out into other software | |
31 | (stubs, etc.), you mustn't disturb the assigned numbering. If you | |
32 | need to add new signals here, add them to the end of the explicitly | |
1a79372d DJ |
33 | numbered signals, at the comment marker. Add them unconditionally, |
34 | not within any #if or #ifdef. | |

35 | |
36 | This is based strongly on Unix/POSIX signals for several reasons: | |
37 | (1) This set of signals represents a widely-accepted attempt to | |
38 | represent events of this sort in a portable fashion, (2) we want a | |
39 | signal to make it from wait to child_wait to the user intact, (3) many | |
40 | remote protocols use a similar encoding. However, it is | |
41 | recognized that this set of signals has limitations (such as not | |
42 | distinguishing between various kinds of SIGSEGV, or not | |
43 | distinguishing hitting a breakpoint from finishing a single step). | |
44 | So in the future we may get around this either by adding additional | |
45 | signals for breakpoint, single-step, etc., or by adding signal | |
46 | codes; the latter seems more in the spirit of what BSD, System V, | |
47 | etc. are doing to address these issues. */ | |
