The C28x compiler supports C++ as defined in the ANSI/ISO/IEC 14882:2003 standard (C++03), including these features:

Complete C++ standard library support, with exceptions noted below.
Templates
Exceptions, which are enabled with the --exceptions option; see Section 6.7.
Run-time type information (RTTI), which can be enabled with the --rtti compiler option.

The compiler supports the 2003 standard of C++ as standardized by the ISO. However, the following features are not implemented or fully supported:

The compiler does not support embedded C++ run-time-support libraries.
The library supports wide chars (wchar_t), in that template functions and classes that are defined for char are also available for wchar_t. For example, wide char stream classes wios, wiostream, wstreambuf and so on (corresponding to char classes ios, iostream, streambuf) are implemented. However, there is no low-level file I/O for wide chars. Also, the C library interface to wide char support (through the C++ headers <cwchar> and <cwctype>) is limited as described above in the C library.
If the definition of an inline function contains a static variable, and it appears in multiple compilation units (usually because it’s a member function of a class defined in a header file), the compiler generates multiple copies of the static variable rather than resolving them to a single definition. The compiler emits a warning (#1369) in such cases.
The export keyword is not implemented.
