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