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