Z-Uno C++ compiler restrictions / enhancement policy

[charly61ch]

Dears,

Restrictions List
Is there an (exhaustive) list available, describing the restrictions applicable to the C++ compiler ?
I think in particular of :

• class/function templates
• static constant members in class
• implicit/explicit casting up, down, of pointers to classes, to inherited classes
• parameters passing of pointer to classes, to inherited classes in a polymorphic way (classes containing virtual functions)

Enhancement policy
Is the goal of the compiler to support more and more c++ compatibilities / features ?
If yes, is it a good practice to submit issues each time we encounter a restriction ?
Is there an approximative "red line" we could "feel", below which we can consider a compiler problem as an issue, and above which, an assumed restriction ?

Thank's in advance for answers/ideas.
Regards,
Charly C.

Hi,
I feel that it's time to write this list. :) You are right uCxx (micro C++) has a lot of restrictions. It's something like first version of C++ (cfront compiler/translator) for x86. It's just an extended C with some of C++ features to simplify porting of Arduino libraries to Z-Uno platform.
We don't plan to support features like templates and complex casting. They are too fat for intel 8051.
However the main polymorphic methods (like virtual functions/constructors) have to work.
