[llvm-dev] RFC: EfficiencySanitizer

[Pete Cooper via llvm-dev]

This is a cool project! Looking forward to seeing what kinds of data we can get.

Is there a good place to discuss potential ideas for this? I don't just want to add more to the end of this thread if you think it'll get unwieldy. Perhaps bugzilla feature requests or something like that?

And +1 to the request for more information on the kinds of things you are planning to write. Would be great to know what you have in mind and then discuss other ideas too.
