I use both "-ffast-math" and "-ftrapping-math" together, and for a while gcc has been spitting the warning message: "warning: -fassociative-math disabled; other options take precedence" For _every_ file I compile, and this is very annoying. While I appreciated the warning the first time, I'd like to turn it off now that I know about the issue. I can do this by explicitly using the "-fno-associative-math" option myself, but I _don't want_ to do this -- if a future release somehow makes figures out a way to make associative-math optimizations work in this situation, I don't want to be in the situation where I've disabled the optimization for no good reason. Does anybody know if there's some option that just turns off the _warning_ without implying that I don't want associative math optimizations? One of the "-Wno-..." options I guess, but I didn't see anything that would handle this case.
