[fpc-devel] Announcement: RTTI extension

[Paul Ishenin]

Hello, FPC developers' list

Please note the following changes regards RTTI for some types:

1. RTTI for Pointers and Class References is now generated by compiler 
with an ability to get a pointed type.

2. RTTI for AnsiStrings now allows to get an initial Code Page an 
AnsiString type (it may be changes at any moment by SetCodePage()).

3. RTTI for arrays has been significantly changed and now is public. 
Previosly RTTI for arrays was used only internally by RTL low level 
functions.

4. RTTI for Procedural Variables now contains information about calling 
convention, arguments and result type.

5. RTTI for Record managed fields has been adjusted to match internal 
compiler reprenstation.

There were few motivations for these changes: user requests, RTL needs 
(AnsiString CodePage) and Delphi compatibility (where that was possible 
and reasonable).

You can find an example of how to deal with this new RTTI and some more 
information by the following link:
