Re: Patch: add systemtap-style marker to _Unwind_DebugHook


Tom,

> Here is an updated version.

I'm fine with that version since it guarantees that it won't break
Solaris bootstrap, as the initial one would have done.

As for DTrace support proper, we can postpone that IMO.  To be honest,
from my experience getting the libgcc unwinder to work with dl_iterate_phdr
on Solaris 11, a single probe in _Unwind_DebugHook may not be enough,
but it's certainly a start.  Maybe we can get at a list of additional
probes to add to the unwinder, perhaps conditionally compiled if there is
unacceptable overhead in production.

Thanks, and sorry for letting the ball drop.

	Rainer
