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