 Hello,
 
 would it be possible for you to check whether this is still the case  
 with gcc 3.3 prerelease? IIRC, Jan Hubricka and others have done a fair  
 bit of work to ensure that P-IV optimized code is as good as or better  
 than i686 code. Alternatively, if you can't build 3.3, can I send you  
 P-IV optimized binaries of your testcase, and see if the problem is  
 still there? Thanks,
 
 Dara
