The exception mechanism does this kind of thing if nothing else does.

Thanks. Could we unify it across backends? -- Andrei

All GCC builtins are available in GDC. Just import gcc.builtins: http://goo.gl/vYhfsC

Unification should probably be done in druntime. I don't see a point in implementing special handling for one builtin in the ldc or gdc compilers as we already handle many (or all) builtins in the compiler in some generic way.
