Swi++

Swi++ is a C++ reimplementation of the _swi and _swix functions from the RISC OS C libraries. It is in the form of a C++ header file generated by a Perl program, which uses some GNU extensions to C++.

Advantages

• The SWI instructions are inlined when compiling with optimisation.
• Pointer-like classes (eg smart pointers, iterators) can be used to return values from SWIs.
• Limited compile time type checking.
• The design is portable to other processors.

Disadvantages

• Requires GNU C++
• Produces bloated code if compiled without optimisation.
