- Subject: general register used as saving comparison result
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
