/* 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. */
