...ells the unwinder about it. The unwinder, at least the C++ unwinder, calls the personality function in phase 2 telling it that it's in the "cleanup" phase. Not so! If only cleanups are found in phase 1 then the unwinder hits the top of the stack without finding a handler and returns _URC_END_OF_STACK without installing any handlers; note that a cleanup is not considered to be a handler. If the C++ unwinder sees the call to _Unwind_RaiseException return like this then it terminates the program. Cleanups will therefore not have been run. The Ada unwinder behaves differently. If it the call to _...

I have some exception handling which works fine using the JIT. Now I am producing object files and linking them, but the exception handling tables seem to be missing. I call _Unwind_RaiseException and get _URC_END_OF_STACK as a result. I produce my object file using TargetMachine::addPassesToEmitFile and then I link my resulting files with: gcc -o prog input.o -fexceptions I'm sure I'm just missing some option to generate the Dwarf tables, but I can't figure out what it is. For the JIT version I set JI...

Maybe the JIT wraps the program in a big catch-all clause? That would cause cleanups to run, and would explain things if you don't have any catch clauses...
