Hello,
I use FPC 3.0.0 on WinXP, Mageia5 and the latest Raspbian, thanks to the incredible versatility of this
fabulous compiler - and the very appreciated work of you all !
I have a bad experience with $OPTIMIZATION DEADSTORE to report with a long software for numerical
simulation of the solar system with thousands asteroids :
- on winxp, the software produces correct numbers with and without DeadStore
optimisazion enabled.
- on Mageia and Raspbian, the numbers are correct only when DeadStore is disabled. Wrong results are the
same on both computers.
I ran each time the software on the compiling machine (no crosscompilation).
What is the current status of DeadStore on 3.0.2 and/or in the forcoming
version ? Is this problem known ?
Cheers, Beppe.
{$IFDEF VER3}
{$OPTIMIZATION DEADVALUES}
{ $OPTIMIZATION DEADSTORE} { if enabled, wrong results }
{$OPTIMIZATION DFA}
{$OPTIMIZATION ORDERFIELDS}
{$OPTIMIZATION FASTMATH}
{$OPTIMIZATION CONSTPROP}
{$ENDIF}
