Hi all,

 From gcc documents, I know that if the condition code or comparison  
result can be placed in any general register, or if there are multiple  
condition registers, use a pseudo register. I want to use general  
register, but I don't know how to do it. Could someone know that? And  
show me some example?


Best regards


Maggie
