C++11
-----
This project currently aims to compile with g++ 4.2.1 and so doesn't make any
use of C++11 features. It would be a good idea to relax this restriction once
clang is the default compiler for ARM, MIPS and PowerPC.
This project uses C++11, as the goal for FreeBSD 11 is to require C/C++11 as a
minimum, either from clang or an external toolchain. In particular, it uses
`std::unique_ptr` extensively for memory management within the tree. Unique
pointers are also used in several other places to track ownership.
This code makes use of a lot of iterator loops, which would be cleaner using
the new syntax in C++11. It also explicitly deletes a lot of objects held in
collections in destructors that have these collections as their members. This
could be simplified by using `shared_ptr`.
Most iterator loops use the new loop syntax and the `auto` type for type
deduction. Range-based `for` loops generally improve the readability of the
code, though `auto` should only be used in places where the type can be deduced
as easily by the reader as by the compiler.
The code does make use of `static_assert()`, but uses a macro in utility.hh to
remove these if they are not supported. The FreeBSD standard headers also
define a compatibility macro the implements static asserts in terms of an array
with 1 element on success and -1 elements on failure.
The code also makes use of `static_assert()` to track compile-time invariants.
