| 26 | /* The numbering of these signals is chosen to match traditional unix
|
|---|
| 27 | signals (insofar as various unices use the same numbers, anyway).
|
|---|
| 28 | It is also the numbering of the GDB remote protocol. Other remote
|
|---|
| 29 | protocols, if they use a different numbering, should make sure to
|
|---|
| 30 | translate appropriately.
|
|---|
| 31 |
|
|---|
| 32 | Since these numbers have actually made it out into other software
|
|---|
| 33 | (stubs, etc.), you mustn't disturb the assigned numbering. If you
|
|---|
| 34 | need to add new signals here, add them to the end of the explicitly
|
|---|
| 35 | numbered signals, at the comment marker. Add them unconditionally,
|
|---|
| 36 | not within any #if or #ifdef.
|
|---|
| 37 |
|
|---|
| 38 | This is based strongly on Unix/POSIX signals for several reasons:
|
|---|
| 39 | (1) This set of signals represents a widely-accepted attempt to
|
|---|
| 40 | represent events of this sort in a portable fashion, (2) we want a
|
|---|
| 41 | signal to make it from wait to child_wait to the user intact, (3) many
|
|---|
| 42 | remote protocols use a similar encoding. However, it is
|
|---|
| 43 | recognized that this set of signals has limitations (such as not
|
|---|
| 44 | distinguishing between various kinds of SIGSEGV, or not
|
|---|
| 45 | distinguishing hitting a breakpoint from finishing a single step).
|
|---|
| 46 | So in the future we may get around this either by adding additional
|
|---|
| 47 | signals for breakpoint, single-step, etc., or by adding signal
|
|---|
| 48 | codes; the latter seems more in the spirit of what BSD, System V,
|
|---|
| 49 | etc. are doing to address these issues. */
