llvm/clang 3.0-1 silently ignores C++ exception handling

[Christian Franke <Christian dot Franke at t-online dot de>]

Clang++ 3.0-1 does not produce any exception handling code. Unwind 
tables and code within catch(.) {...} blocks are not generated. Throw 
always abort()s program.

$ cat trycatch.cc
void do_work();
void handle_error();

void func()
{
  try { do_work();  }
  catch (...) { handle_error(); }
}

$ clang++ -fexceptions -S trycatch.cc

$ grep handle_error trycatch.s

$ cat trycatch.s
...
__Z4funcv:
        pushl   %ebp
        movl    %esp, %ebp
        subl    $8, %esp
        calll   __Z7do_workv
        addl    $8, %esp
        popl    %ebp
        ret


$ g++ -S trycatch.cc

$ grep handle_error trycatch.s
        call    __Z12handle_errorv


Is this as excepted?
