[PATCH] Generate unwind info for pthread_sighandler*

[PATCH] Generate unwind info for pthread_sighandler*

[Jakub Jelinek]

Hi!

I think one should be able to unwind through the pthread
signal handler wrappers (e.g. libjava currently uses very ugly workarounds
because of this).
Or would you prefer instead moving those 2 functions into separate source
file and add exceptions just to that file?

I certainly prefer this.  The patch I checked in should do it.

But for the records: throwing exceptions from signal handlers wwas never
tested nor was it part of the "design".  If it works it's accidental. 
If it doesn't work that the reality to work with.
