There was an argument over making the -pipe the default a few months ago, but I was under the impression that it didn't happen because some people were concerned about the memory requirements nixing compiles on machines with small amounts of memory (since cpp, cc1, AND as wind up all running simultaniously). The documentation doesn't indicate that -pipe is turned on by default. If I ktrace a cc command it sure looks like it uses /tmp files when -pipe is not specified! So I would say that -pipe is NOT the default. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
