I mean, the positive in `Inner::Inner()`, which has regressed, was written long before the notion of "almost-trivial constructor" was introduced by you. So it shouldn't be a problem if we modify this test to let the constructor become non-almost-trivial; that wasn't the purpose of that particular test. And we could create another test with almost-trivial constructor elsewhere, which would prove the usefulness of your patch. > > 2.

Yeah, that's what i thought - not completely commented out, just having an opposite expected-warning <=> no-warning, and a "FIXME: we should (not) warn here because *some hand-waving*".

I think this test should still test what it used to test - i've a feeling it's ok if we modify the part of it that was not related to what it used to test, but i'm feeling bad about removing it completely. Essentially, this plan of mine has the sole purpose of keeping my (and perhaps somebody else's) conscience from biting me for removing the test; it seems that simpler approaches seem to carry more of the "no-no, this shouldn't happen" feeling. I guess i could post a patch-over-a-patch if what i'm expressing isn't clear. https://reviews.llvm.org/D22374 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
