[PATCH] D110216: [clang] retain type sugar in auto / template argument deduction

[Hans Wennborg via Phabricator via cfe-commits]

hans added a comment.

We're seeing a diagnostic change in Chromium which looks funny. For the following code (span<> is our own class):

  int WontCompile() {
    const std::vector<int> v;
    span<int> s = make_span(v);
  }

the diagnostic changes from:

  fatal error: no viable conversion from 'span<const int, [...]>' to 'span<int, [...]>

to

  fatal error: no viable conversion from 'span<T, [...]>' to 'span<int, [...]>

This looks very strange.
