>I take it you have tests in your product repos that test your compiler behaviour, including optimisations that you enable while building binaries, and all third party dependencies you use. Is that accurate?
Are you asking whether I write integration tests? Yes, I do. And at work there's a whole lot of acceptance testing too.
>There is a difference between "gcc 4.8 is buggy, let's not use it" and "let's write unit tests for gcc".
They're not proposing writing unit tests for gcc, only actually testing what gcc produces from their source. You know, by executing it like tests tend to do. Testing only the first party source would mean relying entirely on static source code analysis instead.
