* Simplify LowerCallTo by using a callsite.Duncan Sands2007-12-191-41/+27
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45198 91177308-0d34-0410-b5e6-96231b3b80d8
* The C++ exception handling personality function wantsDuncan Sands2007-12-193-28/+60
| | | | | | | | | | | | | | | | | | | | | | | | 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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45197 91177308-0d34-0410-b5e6-96231b3b80d8
