People following the svn changes recently might have noticed that a lot of changes regarding win64 happened. So we're proud to announce the first x86_64-win64 snapshot which is also probably the first available OSS compiler for win64.

ftp://ftpmaster.freepascal.org/pub/fpc/snapshot/v21/x86_64-win64/fpc-2.1.1.x86_64-win64.zip

It is far from being ready for production use, but for first tests it should be usefull.

Please note that the x86_64 win64 needs the internal linker so programs must be compiled with -Xi

Awaiting your feedback and patches to improve it :)

Great! We have made our SecureBlackbox library available for compilation with FreePascal and we hope to use FreePascal for building 64-bit versions of SecureBlackbox.

What are the main issues to be aware of when building the code with this version?

Sincerely yours,
Eugene Mayevski

Unknown yet, that's why this snapshot is available: to find out these issues :)

Congratulations! Is a new compiler define planned which distinguishes between 32 and 64 bits, irrespective of the os targeted?

What do you mean with this?

To declare conditional defines like this easily:

{$ifdef cpu64}
TMyInteger = Int64;
{$else}
TMyInteger = LongInt;
{$endif}

http://www.freepascal.org/wiki/index.php/Writing_portable_code_regarding_the_processor_architecture#32_Bit_vs._64_Bit

And of course the documentation:

http://www.freepascal.org/docs-html/prog/prog.html

more specifically:

http://www.freepascal.org/docs-html/prog/progap7.html#x291-293000G

Amazing, isn't it ;-)

Amazing discoveries indeed, but how do these documents relate to my question specifically, i.e. how to fill in the mssign word:

{$ifdef ?????}

TMyInteger = Int64; {$else} TMyInteger = LongInt; {$endif}

There was the correct cpu64 in your previous mail :)?

So cpu64 will be the define refering to all brands of 64 bits cpu's on all flavours of 64 bits os?

Yes. cpu64 means 64 bit pointers.

Is there any publication page about this, on the wiki or fpc website? So anybody else are able to spread this great news.

Congratulations to FPC development team! :)

Well:

begin
   {$if sizeof(pointer)=4 }
     Writeln('4');
   {$else }
     Writeln('8');
   {$endif }
end.

or

begin
   {$ifdef CPU64 }
     Writeln('8');
   {$else }
     Writeln('4');
   {$endif }
end.

or

begin
   {$ifdef CPU32 }
     Writeln('4');
   {$else }
     Writeln('8');
   {$endif }
end.

I hope our PR deparment works on it ;)

You can better use the special type for it directly instead of adding $ifdef's

  TMyInteger = PtrInt;
  TMyWord = PtrUInt;
