Introduce a compatibility layer for C++11 code by adding
include/abg-cxx-compat.h. abg-cxx-compat defines a new namespace
abg_compat and defines
abg_compat::hash
abg_compat::shared_ptr
abg_compat::weak_ptr
abg_compat::dynamic_pointer_cast
abg_compat::static_pointer_cast
abg_compat::unordered_map
abg_compat::unordered_set
based on definitions from std::tr1 (std=gnu++98) or std:: (std=gnu++11).
I decided for introducing abg_compat:: rather than polluting abigail::
to allow an easier transition to C++11 at a later time and to not subtly
break existing code.
As the shared_ptr in C++11 defines shared_ptr::operator bool() explicit,
some locations where a shared_ptr is assigned to boolean, needed to be
adjusted to explicitly cast to bool.
* include/abg-cxx-compat.h: new file introducing the abg_compat
namespace to provide C++11 functionality from either std::tr1
or std::
* include/Makefile.am: Add the new abg-cxx-compat.h to source
distribution.
* include/abg-comparison.h: replace std::tr1 usage by abg_compat
and adjust includes accordingly: likewise
* include/abg-diff-utils.h: likewise
* include/abg-fwd.h: likewise
* include/abg-ini.h: likewise
* include/abg-interned-str.h: likewise
