/* 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. */
