...h the ability to emit ODR tables using ODR hashes - LLD will be extended to read ODR tables from object files I have implemented a prototype of this feature. It is available here: https://github.com/pcc/llvm-project/tree/odr-checker and some results from applying it to chromium are here: crbug.com/726071 As you can see it did indeed find a number of real ODR violations in Chromium, including some that wouldn't be detectable using debug info. If you're interested in what the format of the ODR table would look like, that prototype shows pretty much what I had in mind, but I expect many other...

Dear R development Team: I really know very little, so you may ignore this post. I have found that my students often make the mistake of mixing up comparisons and assignments with negative numbers: if (x<-3) do_something; I parenthesize, but every once in a while, I forget and commit this mistake, too. so, I would suggest that R simply warn about an ambiguity. that is, it could suggest
