[Bf-committers] MSVC compiler optimize flags

[Peter den Bak]

Hi,

/O1 and /O2 also do the trick, and are slightly faster.

Regards,

Peter

Subject: [Bf-committers] MSVC compiler optimize flags

Hi,

While hunting a bug in the windows version, it appears that errors can  
happenn with certain compiler flags, and only in MSVC7, not in MSVC6  
(or so!).

http://projects.blender.org/tracker/index.php? 
func=detail&aid=1842&group_id=9&atid=125

Peter found a compiler option (/Ox) that seems to solve this error, but  
I'd appreciate an investigation what really goes on...

- Are the default compile flags OK?
- Is nothing affecting floating point precision?
- Or maybe something that moves pointers to negative addresses?

Thanks!
