digitalmars.D - Unanswered ABI questions (Walter?)

Hi,

some days ago i had some problems with the D ABI (still not documented on  
the homepage). Nobody has answered yet. It would be very kind if Walter or  
another one with detailed knowledge of the ABI could give a short answer  
to the questions.

This is the original post:
digitalmars.D/25537

Questions summed up:

* How to reference a member of a foreign class in assembler?
* Which registers need to be preserved by a function?
* "this" pointer of member functions is always in EAX?
* How to load floating point constants into the FPU?

Thanks a lot!
