<) While modified by TI,
library support most closely resembles that of libc++ 5.0.1.
Supported compilers default to and only support C++14 mode for compilation of
C++ source files. C++14 object files are incompatible with C++03 object files.
C compatibility is not affected by this change.
While most C++03 should compile without a problem, there are a couple of
incompatibilities at the language level you might encounter while recompiling
your old C++ source code:
## New Keywords
* **alignas**
* **alignof**
* **char16_t**
* **char32_t**
* **constexpr**
* **decltype**
* **noexcept**
* **nullptr**
* **static_assert**
* **thread_local**
## Repurposed or deprecated keywords
* **auto** is no longer a storage class specifier, but has been repurposed as a
type specifier
* **register** has been deprecated and will be removed in a later version
## Aggregate initialization no longer allows narrowing conversions
```cpp
int x[] = { 2.0 }; // Previously compiled, but now results in a syntax error
```
## New literal prefixes and suffixes could cause macro replacement to fail
```cpp
#define u8 "abc"
const char *s1 = u8"def"; // Previously "abcdef", now "def"
#define _x "there"
const char *s2 = "hello "_x; // Previously "hello there", now a syntax error
```
