C++ support

[Mitesh Shah]

Hi,

Has any one have any idea about how to sparse C++ code? Is there any wrapper or converter to convert it to C before passing it to sparse? 

Thanks,

Sparse doesn't support C++ natively.  In theory, someone could write a C++
frontend that provides similar output to the C frontend (same data structures
and linearized bytecode format), but barring someone providing the *huge* pile
of code this would require *and* committing to support it, I don't see this
happening anytime soon.  (That said, if someone genuinely has an interest in
doing so, feel free to contact linux-sparse@vger.kernel.org to coordinate.)

Some tools exist to translate C++ to C, most of them proprietary and most of
them quite old.  Some of them come from the days when everyone used such tools
to compile C++ in the first place.  To the best of my knowledge, all of these
tools primarily target the ability to compile with a C compiler; they don't
target easily readable C code.  If you could manage to get the Sparse keywords
to pass through them into the C code, you *might* manage to get some useful
semantic warnings out of one of them, such as locking validation or
user/kernel pointer checking, though you'd have to wade through a lot of noise
to find them.
