/* Under NetBSD/i386, signal handler invocations can be identified by the

|
|
designated code sequence that is used to return from a signal handler.
|
|
|
|
In particular, the return address of a signal handler points to the
|
|
|
|
following code sequence:
|
|
|
|
|
|
|
|
leal 0x10(%esp), %eax

|
Each instruction has a unique encoding, so we simply attempt to match
|
|
|
|
the instruction the PC is pointing to with any of the above instructions.
|
|
|
|
If there is a hit, we know the offset to the start of the designated
|
|
|
|
sequence and can then check whether we really are executing in the
|
|
|
|
signal trampoline. If not, -1 is returned, otherwise the offset from the

|
|
start of the return sequence is returned. */
