230 /* The numbering of these signals is chosen to match traditional unix
231 signals (insofar as various unices use the same numbers, anyway).
232 It is also the numbering of the GDB remote protocol. Other remote
233 protocols, if they use a different numbering, should make sure to
234 translate appropriately.
236 Since these numbers have actually made it out into other software
237 (stubs, etc.), you mustn't disturb the assigned numbering. If you
238 need to add new signals here, add them to the end of the explicitly
241 This is based strongly on Unix/POSIX signals for several reasons:
242 (1) This set of signals represents a widely-accepted attempt to
243 represent events of this sort in a portable fashion, (2) we want a
244 signal to make it from wait to child_wait to the user intact, (3) many
245 remote protocols use a similar encoding. However, it is
246 recognized that this set of signals has limitations (such as not
247 distinguishing between various kinds of SIGSEGV, or not
248 distinguishing hitting a breakpoint from finishing a single step).
249 So in the future we may get around this either by adding additional
250 signals for breakpoint, single-step, etc., or by adding signal
251 codes; the latter seems more in the spirit of what BSD, System V,
252 etc. are doing to address these issues. */
