Dumb. 4091, # C4127: conditional expression is constant # This warning can in theory catch dead code and other problems, but # triggers in far too many desirable cases where the conditional # expression is either set by macros or corresponds some legitimate # compile-time constant expression (due to constant template args, # conditionals comparing the sizes of different types, etc.). Some of # these can be worked around, but it's not worth it. 4127, # C4351: new behavior: elements of array 'array' will be default # initialized # This is a silly "warning" that basically just alerts you that the # compiler is going to actually follow the language spec like it's # supposed to, instead of not following it like old buggy versions # did. There's absolutely no reason to turn this on. 4351, # C4355: 'this': used in base member initializer list # It's commonly useful to pass |this| to objects in a class' # initializer list. While this warning can catch real bugs, most of # the time the constructors in question don't attempt to call methods # on the passed-in pointer (until later), and annotating every legit # usage of this is simply more hassle than the warning is worth. 4355, # C4503: 'identifier': decorated name length exceeded, name was # truncated # This only means that some long error messages might have truncated # identifiers in the presence of lots of templates. It has no effect # on program correctness and there's no real reason to waste time # trying to prevent it. 4503, # Warning C4589 says: "Constructor of abstract class ignores # initializer for virtual base class." Disable this warning because it # is flaky in VS 2015 RTM. It triggers on compiler generated # copy-constructors in some cases. 4589, # C4611: interaction between 'function' and C++ object destruction is # non-portable # This warning is unavoidable when using e.g. setjmp/longjmp. MSDN # suggests using exceptions instead of setjmp/longjmp for C++, but # Chromium code compiles without exception support. We therefore have # to use setjmp/longjmp for e.g. JPEG decode error handling, which # means we have to turn off this warning (and be careful about how # object destruction happens in such cases). 4611, # TODO(thestig): These warnings are level 4.
