Preprocessor Macros

Hi all,

I'm just wondering are there any Microsoft C/C++ preprocessor macros defined for the newer single  and dual core CPU's or do they all have 600 as their _m_IX86 value. My reason for asking is that I have a dual core Athlon 64 processor, running 32-Bit Windows XP. I would have thought that the sheer fact that it is a differenct manufacturer would make a difference.


Regards

When you use the /Gn flag, it sets the _M_IX86 flag. The default is /GB which sets this to 600, but there's /G7 which sets it to 700, and optimises for the P4 & Athlon. I haven't got the latest compiler, but try to see what values you have available in your help. Perhaps a /G8 or /G9?
