Hello,


About volatile attribute..

I have just read the following about volatile from Barry Kelly:

"Specifically, volatile prevents the compiler from changing the number
of reads or writes to or from a location from the number that are
explicitly indicated in the source. That doesn't mean that the reads or
writes to volatile locations will act as memory barriers.

To my knowledge, current implementations of Win32 Delphi never change
the number or order of reads or writes to global variables or fields of objects."

Read more here:

http://borland.newsgroups.archived.at/public.delphi.language.delphi.win32/200606/0606232337.html

So i think the old Delphi compilers that don't support volatile never change the number or order of reads or writes to global variables or fields of objects, and i think since Freepascal in the Delphi mode is compatible
with the old Delphi compilers that don't support volatile, so then
Freepascal in the Delphi mode never change the number or order of reads
or writes to global variables or fields of objects.


Thank you,
Amine Moulay Ramdane.
