> But on 64-bit windows the default exception handling (SEH) uses a similar mechanism than Linux and should have comparable performance. AFAIK SEH in Windows calls RaiseException() which in turn causes a user/kernel mode transition, probes for exception/termination handlers, and vectored exception handlers depending on the severity. It's been a while but I'm not sure the code GCC generates in Linux is quite like this. |
