/* Convert SIM_SIGFOO to SIGFOO.
|

|
|
What to do when the host doesn't have SIGFOO is handled on a case by case
|
||
|
|
basis. Generally, in the case of passing a value back to gdb, we want gdb
|
||
|
|
to not think the process has died (so it can be debugged at the point of
|
||
|
|
failure). */
