ScummVM is written in a subset of C++11. Due to limitations of the C++ run-times on various platforms, the following features cannot currently be used:
* C++ exceptions (throw/catch): Not all C++ compilers support these correctly (esp. on embedded systems), and exception support incurs a noticeable overhead in binary size.
* C++ exceptions (throw/catch): Not all C++ compilers support these correctly (esp. on embedded systems), and exception support incurs a noticeable overhead in binary size.
* Global C++ objects: Their constructors / destructors will not be called on certain targets, causing all kinds of bad problems and requiring ugly workarounds. (The GCC option -Wglobal-constructors helps finding code doing this.)
