Attribute aligned??

["Sylvain Becker" <sybecker@xxxxxxxx>]

Hello, 

I d like to understand more precisely the "aligned" attribute. 

After I write :
FOO bar __attribute__((aligned(8))); 

what should be the correct adress of bar (&bar) ?  
should  I have $bar == k * 8   ?


thanks for your help,

Sylvain
