The following lists the new and changed features in this release of version 5.13 specific to the C++ compiler. For more information, see the CC (1) man page.
The C++ compiler changes include the changes that are described in New and Changed Features Common to the Compilers.
For details, see the Oracle Solaris Studio 12.4: C++ User’s Guide and the CC man page.
Support for –compat=g on all platforms .
New compiler option: –std enables selection of either C++ 03 or C++ 11 dialect with g++ binary compatibility. When using –std=c++11, the following limitations apply:
Universal Character Names (escaped Unicode characters) are not currently supported.
The non-standard iostream headers ending in .h, such as <iostream.h>, <fstream.h>, etc., are not available. These headers were intended to ease the transition from old-style C++ to C++98.
New compiler option: –features=[no%]rtti disables runtime type identification (RTTI).
New compiler option: –xprevise produces a static analysis of the source code that can be viewed in Code Analyzer.
The following options that have -xoption equivalents are now deprecated:
Instead you should use –xhelp, –xinline, –xlibmieee and so on.
Support for –xregs=float on x86.
Behavior for –errtags is now the same as for the C compiler, emitting tags only for warning messages. In previous C++ compilers, the –errtags option caused a tag to be printed as part of the message for both warnings and errors.
Default –template option changing from –template=extdef to –template=no%extdef.
This change is because no other compiler uses the definitions separate template model that is assumed by –template=extdef. The –template=extdef option imposes strict requirements on how source code is organized, which most code does not follow. Unless you develop only with Oracle Solaris Studio C++, it is likely that the –template=no%extdef option is needed.
