CoreCLR on Mac: Experience managed exception handling

C # test Code:

usingSystem;classprogram{Static voidA () {Try{Console.WriteLine ("throwing an exception"); Throw NewException ("did you catch it?"); }        finally{Console.WriteLine ("a.finally ()"); }    }    Static voidB () {Try{C (); Console.WriteLine ("failure! Exception have not been thrown."); }        Catch(Exception ex) {Console.WriteLine ("Test b:success! Caught exception!\n"+Ex.        ToString ()); }        finally{Console.WriteLine ("b.finally ()"); }    }    Static voidC () {A (); }    Static voidD () {Try        {            Try{Console.WriteLine ("throwing an exception"); Throw NewException ("did you catch it in the right handler?"); }            Catch(IndexOutOfRangeException e) {Console.WriteLine ("Test d:failed. Called Wrong handler.\n"+e.tostring ()); }        }        Catch(Exception ex) {Console.WriteLine ("Test d:success! Caught exception!\n"+Ex.

Throw Exception

Code compilation:

Mcs-nostdlib  -r:compile_r_lib/mscorlib.dll-r:compile_r_lib/system.runtime.dll-r:compile_r_lib/ System.Console.dll App/throwexception.cs

Code to run:

Runtime_mac/corerun App/throwexception.exe

Running results when managed exception handling is not implemented:

Testing athrowing an exception{0x7fff7c0e1300-0x108e7c840} ASSERT [DEBUG  ] at/git/dotnet/coreclr/src/pal/src/ ARCH/I386/CONTEXT.CPP.38:TRACE/BPT Trap:5

The results of the operation after the initial implementation of managed exception handling:
