22/* The numbering of these signals is chosen to match traditional unix
23   signals (insofar as various unices use the same numbers, anyway).
24   It is also the numbering of the GDB remote protocol.  Other remote
25   protocols, if they use a different numbering, should make sure to
26   translate appropriately.
27
28   Since these numbers have actually made it out into other software
29   (stubs, etc.), you mustn't disturb the assigned numbering.  If you
30   need to add new signals here, add them to the end of the explicitly
31   numbered signals, at the comment marker.  Add them unconditionally,
32   not within any #if or #ifdef.
33
34   This is based strongly on Unix/POSIX signals for several reasons:
35   (1) This set of signals represents a widely-accepted attempt to
36   represent events of this sort in a portable fashion, (2) we want a
37   signal to make it from wait to child_wait to the user intact, (3) many
38   remote protocols use a similar encoding.  However, it is
39   recognized that this set of signals has limitations (such as not
40   distinguishing between various kinds of SIGSEGV, or not
41   distinguishing hitting a breakpoint from finishing a single step).
42   So in the future we may get around this either by adding additional
43   signals for breakpoint, single-step, etc., or by adding signal
44   codes; the latter seems more in the spirit of what BSD, System V,
45   etc. are doing to address these issues.  */
