| 22 | /* The numbering of these signals is chosen to match traditional unix |
|---|
| 23 | signals (insofar as various unices use the same numbers, anyway). |
|---|
| 24 | It is also the numbering of the GDB remote protocol. Other remote |
|---|
| 25 | protocols, if they use a different numbering, should make sure to |
|---|
| 26 | translate appropriately. |
|---|
| 27 | |
|---|
| 28 | Since these numbers have actually made it out into other software |
|---|
| 29 | (stubs, etc.), you mustn't disturb the assigned numbering. If you |
|---|
| 30 | need to add new signals here, add them to the end of the explicitly |
|---|
| 31 | numbered signals, at the comment marker. Add them unconditionally, |
|---|
| 32 | not within any #if or #ifdef. |
|---|
| 33 | |
|---|
| 34 | This is based strongly on Unix/POSIX signals for several reasons: |
|---|
| 35 | (1) This set of signals represents a widely-accepted attempt to |
|---|
| 36 | represent events of this sort in a portable fashion, (2) we want a |
|---|
| 37 | signal to make it from wait to child_wait to the user intact, (3) many |
|---|
| 38 | remote protocols use a similar encoding. However, it is |
|---|
| 39 | recognized that this set of signals has limitations (such as not |
|---|
| 40 | distinguishing between various kinds of SIGSEGV, or not |
|---|
| 41 | distinguishing hitting a breakpoint from finishing a single step). |
|---|
| 42 | So in the future we may get around this either by adding additional |
|---|
| 43 | signals for breakpoint, single-step, etc., or by adding signal |
|---|
| 44 | codes; the latter seems more in the spirit of what BSD, System V, |
|---|
| 45 | etc. are doing to address these issues. */ |
