139 | NOTE: cagney/2000-03-14: | |

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