14 years agoThe C++ exception handling personality function wants
Duncan Sands [Wed, 19 Dec 2007 07:36:31 +0000 (07:36 +0000)]
The C++ exception handling personality function wants
to know about calls that cannot throw ('nounwind'):
if such a call does throw for some reason then the
personality will terminate the program.  The distinction
between an ordinary call and a nounwind call is that
an ordinary call gets an entry in the exception table
but a nounwind call does not.  This patch sets up the
exception table appropriately.  One oddity is that
I've chosen to bracket nounwind calls with labels (like
invokes) - the other choice would have been to bracket
ordinary calls with labels.  While bracketing
ordinary calls is more natural (because bracketing
by labels would then correspond exactly to getting an
entry in the exception table), I didn't do it because
introducing labels impedes some optimizations and I'm
guessing that ordinary calls occur more often than
nounwind calls.  This fixes the gcc filter2 eh test,
at least at -O0 (the inliner needs some tweaking at
higher optimization levels).
