Wow, this is a bold statement :-) Is C++ such a small world?
What about Sun compiler for instance? EDG lists it as a different "dialect".
> Mathworks is almost certainly licensing from EDG.
... by ruling out the two others?
In any case this is where the backend comes from:

LCA: Static analysis with GCC plugins Posted Jan 24, 2010 20:34 UTC (Sun) by JoeBuck (subscriber, #2330) [Link] Sun's compiler accepts a non-standard dialect, which they froze long ago and won't fix based on backward compatibility arguments. They provide two different "standard libraries", the default, broken one and a better one based on STLPort. Getting modern C++ code to pass Sun's compiler is a real chore.

IBM's C++ compiler also has its own front end.
Only 3 real C++ parsers Posted Jan 29, 2010 16:47 UTC (Fri) by giraffedata (subscriber, #1954) [Link] IBM's C++ compiler also has its own front end. Meaning what (I don't know what a front end is)? Does it use one of the three stated real C++ parsers? Does it have its own parser which, like Sun's isn't real because it can't parse standard C++?

Front end: the thing which takes a high-level language (e.g. C++) and
yields a language-independent, relatively machine-independent representation for optimization and translation into machine-dependent form. (In recent versions of GCC, this intermediate representation is GIMPLE).
(There is no formal name for this machine-independent part that I know of,

Well, how many _complete_ Java parsers do exist? How many C#?, Python? Perl?

I know at least 5 Java _compilers_. Granted, for Java 1.4, not 1.5. But still...
C++ parsers: A small world Posted Jan 25, 2010 14:26 UTC (Mon) by dwheeler (guest, #1216) [Link] Yes, it really is a small world for *real* C++ parsers. You might be able to add a few, but C++ is really painful to parse. Thus, most people try to use a pre-existing parser rather than rolling their own.
