Makefile.in (calls.o): Depend on except.h.
* Makefile.in (calls.o): Depend on except.h.
* calls.c: Include except.h.
(emit_call_1): Call note_eh_region_may_contain_throw if
appropriate.
* except.c (eh_region): Add may_contain_throw.
(expand_eh_region_end_cleanup): Do not include handler code when
it cannot be reached.
(note_eh_region_may_contain_throw): New function.
* except.h (note_eh_region_may_contain_throw): New function.
* call.c (build_over_call): Use build_cxx_call.
(build_cxx_call): New method, split out of build_over_call.
* cp-tree.h (language_function): Add can_throw.
(build_cxx_call): Declare it.
* decl.c (finish_function): If a function does not contain any
calls to functions that can throw an exception, indicate that
fact.
* decl2.c (mark_used): Do not defer the instantiation of
functions, if the current function does not throw.
* optimize.c (maybe_clone_body): Copy TREE_NOTHROW to the clones.
