/* 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, at the comment marker. Add them unconditionally,
|
|
not within any #if or #ifdef.
|
|
|
|
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. */
