Hello,

Please take a look at the source code of the Delphi XE
DRWLock here:

https://sites.google.com/site/aminer68/scalable-distributed-reader-wr...

I have delclared the following variables in LW_RWLockx.pas
"volatile" like this:

[Volatile] FCount1: PMyRecord1;
[Volatile] FCount2: PMyRecord2;
[Volatile] FCount3: PMyRecord3;
[Volatile] nbr: PMyRecord4;

And i have delclared the following variable in RWLockx.pas
"volatile" like this:

[Volatile] FCount1: PMyRecord1;
[Volatile] FCount2: PMyRecord2;
[Volatile] FCount3: PMyRecord3;
[Volatile] nbr: PMyRecord4;
[Volatile] nbr1: PMyRecord5;


So now you can be more confident of visibility accross cores.


Thank you,
Amine Moulay Ramdane.
